+Introduction
+------------
+
+Firmware often consists of several components which must be packaged together.
+For example, we may have SPL, U-Boot, a device tree and an environment area
+grouped together and placed in MMC flash. When the system starts, it must be
+able to find these pieces.
+
+So far U-Boot has not provided a way to handle creating such images in a
+general way. Each SoC does what it needs to build an image, often packing or
+concatenating images in the U-Boot build system.
+
+Binman aims to provide a mechanism for building images, from simple
+SPL + U-Boot combinations, to more complex arrangements with many parts.
+
+
+What it does
+------------
+
+Binman reads your board's device tree and finds a node which describes the
+required image layout. It uses this to work out what to place where. The
+output file normally contains the device tree, so it is in principle possible
+to read an image and extract its constituent parts.
+
+
+Features
+--------
+
+So far binman is pretty simple. It supports binary blobs, such as 'u-boot',
+'spl' and 'fdt'. It supports empty entries (such as setting to 0xff). It can
+place entries at a fixed location in the image, or fit them together with
+suitable padding and alignment. It provides a way to process binaries before
+they are included, by adding a Python plug-in. The device tree is available
+to U-Boot at run-time so that the images can be interpreted.
+
+Binman does not yet update the device tree with the final location of
+everything when it is done. A simple C structure could be generated for
+constrained environments like SPL (using dtoc) but this is also not
+implemented.
+
+Binman can also support incorporating filesystems in the image if required.
+For example x86 platforms may use CBFS in some cases.
+
+Binman is intended for use with U-Boot but is designed to be general enough
+to be useful in other image-packaging situations.
+
+
+Motivation
+----------
+
+Packaging of firmware is quite a different task from building the various
+parts. In many cases the various binaries which go into the image come from
+separate build systems. For example, ARM Trusted Firmware is used on ARMv8
+devices but is not built in the U-Boot tree. If a Linux kernel is included
+in the firmware image, it is built elsewhere.
+
+It is of course possible to add more and more build rules to the U-Boot
+build system to cover these cases. It can shell out to other Makefiles and
+build scripts. But it seems better to create a clear divide between building
+software and packaging it.
+
+At present this is handled by manual instructions, different for each board,
+on how to create images that will boot. By turning these instructions into a
+standard format, we can support making valid images for any board without
+manual effort, lots of READMEs, etc.
+
+Benefits:
+- Each binary can have its own build system and tool chain without creating
+any dependencies between them
+- Avoids the need for a single-shot build: individual parts can be updated
+and brought in as needed
+- Provides for a standard image description available in the build and at
+run-time
+- SoC-specific image-signing tools can be accomodated
+- Avoids cluttering the U-Boot build system with image-building code
+- The image description is automatically available at run-time in U-Boot,
+SPL. It can be made available to other software also
+- The image description is easily readable (it's a text file in device-tree
+format) and permits flexible packing of binaries
+
+
+Terminology
+-----------
+
+Binman uses the following terms:
+
+- image - an output file containing a firmware image
+- binary - an input binary that goes into the image
+
+
+Relationship to FIT
+-------------------
+
+FIT is U-Boot's official image format. It supports multiple binaries with
+load / execution addresses, compression. It also supports verification
+through hashing and RSA signatures.
+
+FIT was originally designed to support booting a Linux kernel (with an
+optional ramdisk) and device tree chosen from various options in the FIT.
+Now that U-Boot supports configuration via device tree, it is possible to
+load U-Boot from a FIT, with the device tree chosen by SPL.
+
+Binman considers FIT to be one of the binaries it can place in the image.
+
+Where possible it is best to put as much as possible in the FIT, with binman
+used to deal with cases not covered by FIT. Examples include initial
+execution (since FIT itself does not have an executable header) and dealing
+with device boundaries, such as the read-only/read-write separation in SPI
+flash.
+
+For U-Boot, binman should not be used to create ad-hoc images in place of
+FIT.
+
+
+Relationship to mkimage
+-----------------------
+
+The mkimage tool provides a means to create a FIT. Traditionally it has
+needed an image description file: a device tree, like binman, but in a
+different format. More recently it has started to support a '-f auto' mode
+which can generate that automatically.
+
+More relevant to binman, mkimage also permits creation of many SoC-specific
+image types. These can be listed by running 'mkimage -T list'. Examples
+include 'rksd', the Rockchip SD/MMC boot format. The mkimage tool is often
+called from the U-Boot build system for this reason.
+
+Binman considers the output files created by mkimage to be binary blobs
+which it can place in an image. Binman does not replace the mkimage tool or
+this purpose. It would be possible in some situtions to create a new entry
+type for the images in mkimage, but this would not add functionality. It
+seems better to use the mkiamge tool to generate binaries and avoid blurring
+the boundaries between building input files (mkimage) and packaging then
+into a final image (binman).
+
+
+Example use of binman in U-Boot
+-------------------------------
+
+Binman aims to replace some of the ad-hoc image creation in the U-Boot
+build system.
+
+Consider sunxi. It has the following steps:
+
+1. It uses a custom mksunxiboot tool to build an SPL image called
+sunxi-spl.bin. This should probably move into mkimage.
+
+2. It uses mkimage to package U-Boot into a legacy image file (so that it can
+hold the load and execution address) called u-boot.img.
+
+3. It builds a final output image called u-boot-sunxi-with-spl.bin which
+consists of sunxi-spl.bin, some padding and u-boot.img.
+
+Binman is intended to replace the last step. The U-Boot build system builds
+u-boot.bin and sunxi-spl.bin. Binman can then take over creation of
+sunxi-spl.bin (by calling mksunxiboot, or hopefully one day mkimage). In any
+case, it would then create the image from the component parts.
+
+This simplifies the U-Boot Makefile somewhat, since various pieces of logic
+can be replaced by a call to binman.
+
+
+Example use of binman for x86
+-----------------------------
+
+In most cases x86 images have a lot of binary blobs, 'black-box' code
+provided by Intel which must be run for the platform to work. Typically
+these blobs are not relocatable and must be placed at fixed areas in the
+firmare image.
+
+Currently this is handled by ifdtool, which places microcode, FSP, MRC, VGA
+BIOS, reference code and Intel ME binaries into a u-boot.rom file.
+
+Binman is intended to replace all of this, with ifdtool left to handle only
+the configuration of the Intel-format descriptor.
+
+
+Running binman
+--------------
+
+Type:
+
+ binman -b <board_name>
+
+to build an image for a board. The board name is the same name used when
+configuring U-Boot (e.g. for sandbox_defconfig the board name is 'sandbox').
+Binman assumes that the input files for the build are in ../b/<board_name>.
+
+Or you can specify this explicitly:
+
+ binman -I <build_path>
+
+where <build_path> is the build directory containing the output of the U-Boot
+build.
+
+(Future work will make this more configurable)
+
+In either case, binman picks up the device tree file (u-boot.dtb) and looks
+for its instructions in the 'binman' node.
+
+Binman has a few other options which you can see by running 'binman -h'.
+
+
+Image description format
+------------------------
+
+The binman node is called 'binman'. An example image description is shown
+below:
+
+ binman {
+ filename = "u-boot-sunxi-with-spl.bin";
+ pad-byte = <0xff>;
+ blob {
+ filename = "spl/sunxi-spl.bin";
+ };
+ u-boot {
+ pos = <CONFIG_SPL_PAD_TO>;
+ };
+ };
+
+
+This requests binman to create an image file called u-boot-sunxi-with-spl.bin
+consisting of a specially formatted SPL (spl/sunxi-spl.bin, built by the
+normal U-Boot Makefile), some 0xff padding, and a U-Boot legacy image. The
+padding comes from the fact that the second binary is placed at
+CONFIG_SPL_PAD_TO. If that line were omitted then the U-Boot binary would
+immediately follow the SPL binary.
+
+The binman node describes an image. The sub-nodes describe entries in the
+image. Each entry represents a region within the overall image. The name of
+the entry (blob, u-boot) tells binman what to put there. For 'blob' we must
+provide a filename. For 'u-boot', binman knows that this means 'u-boot.bin'.
+
+Entries are normally placed into the image sequentially, one after the other.
+The image size is the total size of all entries. As you can see, you can
+specify the start position of an entry using the 'pos' property.
+
+Note that due to a device tree requirement, all entries must have a unique
+name. If you want to put the same binary in the image multiple times, you can
+use any unique name, with the 'type' property providing the type.
+
+The attributes supported for entries are described below.
+
+pos:
+ This sets the position of an entry within the image. The first byte
+ of the image is normally at position 0. If 'pos' is not provided,
+ binman sets it to the end of the previous region, or the start of
+ the image's entry area (normally 0) if there is no previous region.
+
+align:
+ This sets the alignment of the entry. The entry position is adjusted
+ so that the entry starts on an aligned boundary within the image. For
+ example 'align = <16>' means that the entry will start on a 16-byte
+ boundary. Alignment shold be a power of 2. If 'align' is not
+ provided, no alignment is performed.
+
+size:
+ This sets the size of the entry. The contents will be padded out to
+ this size. If this is not provided, it will be set to the size of the
+ contents.
+
+pad-before:
+ Padding before the contents of the entry. Normally this is 0, meaning
+ that the contents start at the beginning of the entry. This can be
+ offset the entry contents a little. Defaults to 0.
+
+pad-after:
+ Padding after the contents of the entry. Normally this is 0, meaning
+ that the entry ends at the last byte of content (unless adjusted by
+ other properties). This allows room to be created in the image for
+ this entry to expand later. Defaults to 0.
+
+align-size:
+ This sets the alignment of the entry size. For example, to ensure
+ that the size of an entry is a multiple of 64 bytes, set this to 64.
+ If 'align-size' is not provided, no alignment is performed.
+
+align-end:
+ This sets the alignment of the end of an entry. Some entries require
+ that they end on an alignment boundary, regardless of where they
+ start. If 'align-end' is not provided, no alignment is performed.
+
+ Note: This is not yet implemented in binman.
+
+filename:
+ For 'blob' types this provides the filename containing the binary to
+ put into the entry. If binman knows about the entry type (like
+ u-boot-bin), then there is no need to specify this.
+
+type:
+ Sets the type of an entry. This defaults to the entry name, but it is
+ possible to use any name, and then add (for example) 'type = "u-boot"'
+ to specify the type.
+
+
+The attributes supported for images are described below. Several are similar
+to those for entries.
+
+size:
+ Sets the image size in bytes, for example 'size = <0x100000>' for a
+ 1MB image.
+
+align-size:
+ This sets the alignment of the image size. For example, to ensure
+ that the image ends on a 512-byte boundary, use 'align-size = <512>'.
+ If 'align-size' is not provided, no alignment is performed.
+
+pad-before:
+ This sets the padding before the image entries. The first entry will
+ be positionad after the padding. This defaults to 0.
+
+pad-after:
+ This sets the padding after the image entries. The padding will be
+ placed after the last entry. This defaults to 0.
+
+pad-byte:
+ This specifies the pad byte to use when padding in the image. It
+ defaults to 0. To use 0xff, you would add 'pad-byte = <0xff>'.
+
+filename:
+ This specifies the image filename. It defaults to 'image.bin'.
+
+sort-by-pos:
+ This causes binman to reorder the entries as needed to make sure they
+ are in increasing positional order. This can be used when your entry
+ order may not match the positional order. A common situation is where
+ the 'pos' properties are set by CONFIG options, so their ordering is
+ not known a priori.
+
+ This is a boolean property so needs no value. To enable it, add a
+ line 'sort-by-pos;' to your description.
+
+multiple-images:
+ Normally only a single image is generated. To create more than one
+ image, put this property in the binman node. For example, this will
+ create image1.bin containing u-boot.bin, and image2.bin containing
+ both spl/u-boot-spl.bin and u-boot.bin:
+
+ binman {
+ multiple-images;
+ image1 {
+ u-boot {
+ };
+ };
+
+ image2 {
+ spl {
+ };
+ u-boot {
+ };
+ };
+ };
+
+end-at-4gb:
+ For x86 machines the ROM positions start just before 4GB and extend
+ up so that the image finished at the 4GB boundary. This boolean
+ option can be enabled to support this. The image size must be
+ provided so that binman knows when the image should start. For an
+ 8MB ROM, the position of the first entry would be 0xfff80000 with
+ this option, instead of 0 without this option.
+
+
+Examples of the above options can be found in the tests. See the
+tools/binman/test directory.
+
+
+Special properties
+------------------
+
+Some entries support special properties, documented here:
+
+u-boot-with-ucode-ptr:
+ optional-ucode: boolean property to make microcode optional. If the
+ u-boot.bin image does not include microcode, no error will
+ be generated.
+
+
+Order of image creation
+-----------------------
+
+Image creation proceeds in the following order, for each entry in the image.
+
+1. GetEntryContents() - the contents of each entry are obtained, normally by
+reading from a file. This calls the Entry.ObtainContents() to read the
+contents. The default version of Entry.ObtainContents() calls
+Entry.GetDefaultFilename() and then reads that file. So a common mechanism
+to select a file to read is to override that function in the subclass. The
+functions must return True when they have read the contents. Binman will
+retry calling the functions a few times if False is returned, allowing
+dependencies between the contents of different entries.
+
+2. GetEntryPositions() - calls Entry.GetPositions() for each entry. This can
+return a dict containing entries that need updating. The key should be the
+entry name and the value is a tuple (pos, size). This allows an entry to
+provide the position and size for other entries. The default implementation
+of GetEntryPositions() returns {}.
+
+3. PackEntries() - calls Entry.Pack() which figures out the position and
+size of an entry. The 'current' image position is passed in, and the function
+returns the position immediately after the entry being packed. The default
+implementation of Pack() is usually sufficient.
+
+4. CheckSize() - checks that the contents of all the entries fits within
+the image size. If the image does not have a defined size, the size is set
+large enough to hold all the entries.
+
+5. CheckEntries() - checks that the entries do not overlap, nor extend
+outside the image.
+
+6. ProcessEntryContents() - this calls Entry.ProcessContents() on each entry.
+The default implementatoin does nothing. This can be overriden to adjust the
+contents of an entry in some way. For example, it would be possible to create
+an entry containing a hash of the contents of some other entries. At this
+stage the position and size of entries should not be adjusted.
+
+7. BuildImage() - builds the image and writes it to a file. This is the final
+step.
+
+
+Automatic .dtsi inclusion
+-------------------------
+
+It is sometimes inconvenient to add a 'binman' node to the .dts file for each
+board. This can be done by using #include to bring in a common file. Another
+approach supported by the U-Boot build system is to automatically include
+a common header. You can then put the binman node (and anything else that is
+specific to U-Boot, such as u-boot,dm-pre-reloc properies) in that header
+file.
+
+Binman will search for the following files in arch/<arch>/dts:
+
+ <dts>-u-boot.dtsi where <dts> is the base name of the .dts file
+ <CONFIG_SYS_SOC>-u-boot.dtsi
+ <CONFIG_SYS_CPU>-u-boot.dtsi
+ <CONFIG_SYS_VENDOR>-u-boot.dtsi
+ u-boot.dtsi
+
+U-Boot will only use the first one that it finds. If you need to include a
+more general file you can do that from the more specific file using #include.
+If you are having trouble figuring out what is going on, you can uncomment
+the 'warning' line in scripts/Makefile.lib to see what it has found:
+
+ # Uncomment for debugging
+ # $(warning binman_dtsi_options: $(binman_dtsi_options))
+
+
+Code coverage
+-------------
+
+Binman is a critical tool and is designed to be very testable. Entry
+implementations target 100% test coverage. Run 'binman -T' to check this.
+
+To enable Python test coverage on Debian-type distributions (e.g. Ubuntu):
+
+ $ sudo apt-get install python-pip python-pytest
+ $ sudo pip install coverage

+The behaviour of entries is defined by the Entry class. All other entries are
+a subclass of this. An important subclass is Entry_blob which takes binary
+data from a file and places it in the entry. In fact most entry types are
+subclasses of Entry_blob.
+
+Each entry type is a separate file in the tools/binman/etype directory. Each
+file contains a class called Entry_<type> where <type> is the entry type.
+New entry types can be supported by adding new files in that directory.
+These will automatically be detected by binman when needed.
+
+Entry properties are documented in entry.py. The entry subclasses are free
+to change the values of properties to support special behaviour. For example,
+when Entry_blob loads a file, it sets content_size to the size of the file.
+Entry classes can adjust other entries. For example, an entry that knows
+where other entries should be positioned can set up those entries' positions
+so they don't need to be set in the binman decription. It can also adjust
+entry contents.
+
+Most of the time such essoteric behaviour is not needed, but it can be
+essential for complex images.
+
+
+History / Credits
+-----------------
+
+Binman takes a lot of inspiration from a Chrome OS tool called
+'cros_bundle_firmware', which I wrote some years ago. That tool was based on
+a reasonably simple and sound design but has expanded greatly over the
+years. In particular its handling of x86 images is convoluted.
+
+Quite a few lessons have been learned which are hopefully be applied here.
+
+
+Design notes
+------------
+
+On the face of it, a tool to create firmware images should be fairly simple:
+just find all the input binaries and place them at the right place in the
+image. The difficulty comes from the wide variety of input types (simple
+flat binaries containing code, packaged data with various headers), packing
+requirments (alignment, spacing, device boundaries) and other required
+features such as hierarchical images.
+
+The design challenge is to make it easy to create simple images, while
+allowing the more complex cases to be supported. For example, for most
+images we don't much care exactly where each binary ends up, so we should
+not have to specify that unnecessarily.
+
+New entry types should aim to provide simple usage where possible. If new
+core features are needed, they can be added in the Entry base class.
+
+
+To do
+-----
+
+Some ideas:
+- Fill out the device tree to include the final position and size of each
+ entry (since the input file may not always specify these)
+- Use of-platdata to make the information available to code that is unable
+ to use device tree (such as a very small SPL image)
+- Write an image map to a text file
+- Allow easy building of images by specifying just the board name
+- Produce a full Python binding for libfdt (for upstream)
+- Add an option to decode an image into the constituent binaries
+- Suppoort hierarchical images (packing of binaries into another binary
+ which is then placed in the image)
+- Support building an image for a board (-b) more completely, with a
+ configurable build directory
+- Consider making binman work with buildman, although if it is used in the
+ Makefile, this will be automatic
+- Implement align-end

+
+ U-Boot on x86 needs a single block of microcode. This is collected from
+ the various microcode update nodes in the device tree. It is also unable
+ to read the microcode from the device tree on platforms that use FSP
+ (Firmware Support Package) binaries, because the API requires that the
+ microcode is supplied before there is any SRAM available to use (i.e.
+ the FSP sets up the SRAM / cache-as-RAM but does so in the call that
+ requires the microcode!). To keep things simple, all x86 platforms handle
+ microcode the same way in U-Boot (even non-FSP platforms). This is that
+ a table is placed at _dt_ucode_base_size containing the base address and
+ size of the microcode. This is either passed to the FSP (for FSP
+ platforms), or used to set up the microcode (for non-FSP platforms).
+ This all happens in the build system since it is the only way to get
+ the microcode into a single blob and accessible without SRAM.
+
+ There are two cases to handle. If there is only one microcode blob in
+ the device tree, then the ucode pointer it set to point to that. This
+ entry (u-boot-ucode) is empty. If there is more than one update, then
+ this entry holds the concatenation of all updates, and the device tree
+ entry (u-boot-dtb-with-ucode) is updated to remove the microcode. This
+ last step ensures that that the microcode appears in one contiguous
+ block in the image and is not unnecessarily duplicated in the device
+ tree. It is referred to as 'collation' here.
+
+ Entry types that have a part to play in handling microcode:
+
+ Entry_u_boot_with_ucode_ptr:
+ Contains u-boot-nodtb.bin (i.e. U-Boot without the device tree).
+ It updates it with the address and size of the microcode so that
+ U-Boot can find it early on start-up.
+ Entry_u_boot_dtb_with_ucode:
+ Contains u-boot.dtb. It stores the microcode in a
+ 'self.ucode_data' property, which is then read by this class to
+ obtain the microcode if needed. If collation is performed, it
+ removes the microcode from the device tree.
+ Entry_u_boot_ucode:
+ This class. If collation is enabled it reads the microcode from
+ the Entry_u_boot_dtb_with_ucode entry, and uses it as the

+
+ An image is comprised of a collection of entries each containing binary
+ data. The image size must be large enough to hold all of this data.
+
+ This class implements the various operations needed for images.
+
+ Atrtributes:
+ _node: Node object that contains the image definition in device tree
+ _name: Image name
+ _size: Image size in bytes, or None if not known yet
+ _align_size: Image size alignment, or None
+ _pad_before: Number of bytes before the first entry starts. This
+ effectively changes the place where entry position 0 starts
+ _pad_after: Number of bytes after the last entry ends. The last
+ entry will finish on or before this boundary
+ _pad_byte: Byte to use to pad the image where there is no entry
+ _filename: Output filename for image
+ _sort: True if entries should be sorted by position, False if they
+ must be in-order in the device tree description
+ _skip_at_start: Number of bytes before the first entry starts. These
+ effecively adjust the starting position of entries. For example,
+ if _pad_before is 16, then the first entry would start at 16.
+ An entry with pos = 20 would in fact be written at position 4
+ in the image file.
+ _end_4gb: Indicates that the image ends at the 4GB boundary. This is
+ used for x86 images, which want to use positions such that a
+ memory address (like 0xff800000) is the first entry position.
+ This causes _skip_at_start to be set to the starting memory
+ address.
