The PCBs of the LS-XHL and LS-CHLv2 are almost the same. +The LS-XHL has a faster CPU and more RAM with a wider data bus, therefore +the LS-XHL PCB has two SDRAM chips. Both have a Kirkwood CPU (Marvell +88F6281). The only on-board storage is a 4 Mbit SPI flash which stores the +bootloader and its environment. The linux kernel and the initial ramdisk +are loaded from the hard disk. + + +Rescue Mode +----------- +These linkstations don't have a populated serial port. There is no way to +access an (unmodified) board other than using the netconsole. If you want +to recover from a bad environment setting or an empty environment, you can +do this only with a working network connection. + +Therefore, on entering the resuce mode, a random ethernet address is +generated if no valid address could be loaded from the environment variable +'ethaddr' and a DHCP request is sent. After a successful DHCP response is +received, the network settings are configured and the ncip is unset. Thus +all netconsole packets are broadcasted and you can use the netconsole to +access board from any host within the network segment. To determine the IP +address assigned to the board, you either have to sniff the traffic or +check the logs/leases of your DHCP server. + +The resuce mode is selected by holding the push button for at least one +second, while powering-on the device. The status LED turns solid amber if +the resuce mode is enabled, thus providing a visual feedback. + +Pressing the same button for at least 10 seconds on power-up will erase the +environment and reset the board. In this case the visual indication will +be: +- blinking blue, for about one second +- solid amber, for about nine seconds +- blinking amber, until you release the button + +This ensures, that you still can recover a device with a broken +environment by first erasing the environment and then entering the rescue +mode. + +Once the rescue mode is started, use the ncb binary from the tools/ +directory to access your board. There is a helper script named +'restore_env' to save your changes. It unsets all the network variables +which were set by the rescue mode, saves your changes and then resets the +board. + +The common use case for this is setting a MAC address. Let us assume you +have an empty environment, the board comes up with the amber LED blinking. +Then you enter the rescue mode, connect to the board with the ncb tool and +use the following commands to set your MAC address: + + setenv ethaddr 00:00:00:00:00:00 + run restore_env + +Of course you need to replace the 00:00:00:00:00:00 with your valid MAC +address, which can be found on a sticker on the bottom of your box. + + +Status LED +---------- +blinking blue + Bootloader is running normally. + +blinking amber + No ethaddr set. Use the `Rescue Mode` to set one. + +blinking red + Something bad happend during loading the operating system. + +The default behavior of the linux kernel is to turn on the blue LED. So if +the blinking blue LED changes to solid blue the kernel was loaded +successfully. + + +Power-on Switch +--------------- +The power-on switch is a software switch. If it is not in ON position when +the bootloader starts, the bootloader will disable the HDD and USB power +and stop the fan. Then it loops until the switch is in ON position again, +enables the power and fan again and continue booting. + + +Boot sources +------------ +The environment defines several different boot sources: + +legacy + This is the default boot source. It loads the kernel and ramdisk from the + attached HDD using the original filenames. The load addresses were + modified to support loading larger kernels. But it should behave the same + as the original bootloader. + +hdd + Use this for new-style booting. Loads three files /vmlinuz, /initrd.img + and /dtb from the boot partition. This should work out of the box if you + have debian and the flash-kernel package installed. + +usb + Same as hdd expect, that the files are loaded from an attached USB mass + storage device and the filename for the device tree is kirkwood-lsxhl.dtb + (or kirkwood-lschlv2.dtb). + +net + Same as usb expect, that the file are loaded from the network. + +rescue + Automatically activated if the push button is pressed for at least one + second on power-up. Does a DHCP request and enables the network console. + See `Rescue Mode` for more information. + +You can change the boot source by setting the 'bootsource' variable to the +corresponding value. Please note, that the restore_env script will the the +bootsource back to 'legacy'. + + +Flash map +--------- +00000 - 5ffff u-boot +60000 - 6ffff reserved, may be used to store dtb +70000 - 7ffff u-boot environment + + +Compiling +--------- +make lsxhl_config (or lschlv2_config) +make u-boot.kwb + + +Update your board +----------------- +Just flash the resulting u-boot.kwb to the beginning of the SPI flash.

All rights reserved. + * + * SPDX-License-Identifier: GPL-2.0+ + */ + +Generic Distro Configuration Concept +==================================== + +Linux distributions are faced with supporting a variety of boot mechanisms, +environments or bootloaders (PC BIOS, EFI, U-Boot, Barebox, ...). This makes +life complicated. Worse, bootloaders such as U-Boot have a configurable set +of features, and each board chooses to enable a different set of features. +Hence, distros typically need to have board-specific knowledge in order to +set up a bootable system. + +This document defines a common set of U-Boot features that are required for +a distro to support the board in a generic fashion. Any board wishing to +allow distros to install and boot in an out-of-the-box fashion should enable +all these features. Linux distros can then create a single set of boot +support/install logic that targets these features. This will allow distros +to install on many boards without the need for board-specific logic. + +In fact, some of these features can be implemented by any bootloader, thus +decoupling distro install/boot logic from any knowledge of the bootloader. + +This model assumes that boards will load boot configuration files from a +regular storage mechanism (eMMC, SD card, USB Disk, SATA disk, etc.) with +a standard partitioning scheme (MBR, GPT). Boards that cannnot support this +storage model are outside the scope of this document, and may still need +board-specific installer/boot-configuration support in a distro. + +To some extent, this model assumes that a board has a separate boot flash +that contains U-Boot, and that the user has somehow installed U-Boot to this +flash before running the distro installer. Even on boards that do not conform +to this aspect of the model, the extent of the board-specific support in the +distro installer logic would be to install a board-specific U-Boot package to +the boot partition partition during installation. This distro-supplied U-Boot +can still implement the same features as on any other board, and hence the +distro's boot configuration file generation logic can still be board-agnostic. + +Locating Bootable Disks +----------------------- + +Typical desktop/server PCs search all (or a user-defined subset of) attached +storage devices for a bootable partition, then load the bootloader or boot +configuration files from there. A U-Boot board port that enables the features +mentioned in this document will search for boot configuration files in the +same way. + +Thus, distros do not need to manipulate any kind of bootloader-specific +configuration data to indicate which storage device the system should boot +from. + +Distros simply need to install the boot configuration files (see next +section) in an ext2/3/4 or FAT partition, mark the partition bootable (via +the MBR bootable flag, or GPT legacy_bios_bootable attribute), and U-Boot (or +any other bootloader) will find those boot files and execute them. This is +conceptually identical to creating a grub2 configuration file on a desktop +PC. + +Note that in the absense of any partition that is explicitly marked bootable, +U-Boot falls back to searching the first valid partition of a disk for boot +configuration files. Other bootloaders are recommended to do the same, since +I believe that partition table bootable flags aren't so commonly used outside +the realm of x86 PCs. + +U-Boot can also search for boot configuration files from a TFTP server. + +Boot Configuration Files +------------------------ + +The standard format for boot configuration files is that of extlinux.conf, as +handled by U-Boot's "syslinux" (disk) or "pxe boot" (network). This is roughly +as specified at: + +http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/ + +... with the exceptions that the BootLoaderSpec document: + +* Prescribes a separate configuration per boot menu option, whereas U-Boot + lumps all options into a single extlinux.conf file.

The only case where an array of GPIOs is accepted is when +several GPIOs serve the same function (e.g. a parallel data line). + +The exact purpose of each gpios property must be documented in the device tree +binding of the device. + +The following example could be used to describe GPIO pins used as device enable +and bit-banged data signals: + + gpio1: gpio1 { + gpio-controller + #gpio-cells = <2>; + }; + gpio2: gpio2 { + gpio-controller + #gpio-cells = <1>; + }; + [...] + + enable-gpios = <&gpio2 2>; + data-gpios = <&gpio1 12 0>, + <&gpio1 13 0>, + <&gpio1 14 0>, + <&gpio1 15 0>; + +Note that gpio-specifier length is controller dependent. In the +above example, &gpio1 uses 2 cells to specify a gpio, while &gpio2 +only uses one. + +gpio-specifier may encode: bank, pin position inside the bank, +whether pin is open-drain and whether pin is logically inverted. +Exact meaning of each specifier cell is controller specific, and must +be documented in the device tree binding for the device. Use the macros +defined in include/dt-bindings/gpio/gpio.h whenever possible: + +Example of a node using GPIOs: + + node { + enable-gpios = <&qe_pio_e 18 GPIO_ACTIVE_HIGH>; + }; + +GPIO_ACTIVE_HIGH is 0, so in this example gpio-specifier is "18 0" and encodes +GPIO pin number, and GPIO flags as accepted by the "qe_pio_e" gpio-controller. + +1.1) GPIO specifier best practices +---------------------------------- + +A gpio-specifier should contain a flag indicating the GPIO polarity; active- +high or active-low. If it does, the following best practices should be +followed: + +The gpio-specifier's polarity flag should represent the physical level at the +GPIO controller that achieves (or represents, for inputs) a logically asserted +value at the device. The exact definition of logically asserted should be +defined by the binding for the device. If the board inverts the signal between +the GPIO controller and the device, then the gpio-specifier will represent the +opposite physical level than the signal at the device's pin. + +When the device's signal polarity is configurable, the binding for the +device must either: + +a) Define a single static polarity for the signal, with the expectation that +any software using that binding would statically program the device to use +that signal polarity. + +The static choice of polarity may be either: + +a1) (Preferred) Dictated by a binding-specific DT property. + +or: + +a2) Defined statically by the DT binding itself. + +In particular, the polarity cannot be derived from the gpio-specifier, since +that would prevent the DT from separately representing the two orthogonal +concepts of configurable signal polarity in the device, and possible board- +level signal inversion. + +or: + +b) Pick a single option for device signal polarity, and document this choice +in the binding. The gpio-specifier should represent the polarity of the signal +(at the GPIO controller) assuming that the device is configured for this +particular signal polarity choice. If software chooses to program the device +to generate or receive a signal of the opposite polarity, software will be +responsible for correctly interpreting (inverting) the GPIO signal at the GPIO +controller. + +2) gpio-controller nodes +------------------------ + +Every GPIO controller node must contain both an empty "gpio-controller" +property, and a #gpio-cells integer property, which indicates the number of +cells in a gpio-specifier. + +Example of two SOC GPIO banks defined as gpio-controller nodes: + + qe_pio_a: gpio-controller@1400 { + compatible = "fsl,qe-pario-bank-a", "fsl,qe-pario-bank"; + reg = <0x1400 0x18>; + gpio-controller; + #gpio-cells = <2>; + }; + + qe_pio_e: gpio-controller@1460 { + compatible = "fsl,qe-pario-bank-e", "fsl,qe-pario-bank"; + reg = <0x1460 0x18>; + gpio-controller; + #gpio-cells = <2>; + }; + +2.1) gpio- and pin-controller interaction +----------------------------------------- + +Some or all of the GPIOs provided by a GPIO controller may be routed to pins +on the package via a pin controller. This allows muxing those pins between +GPIO and other functions. + +It is useful to represent which GPIOs correspond to which pins on which pin +controllers. The gpio-ranges property described below represents this, and +contains information structures as follows: + + gpio-range-list ::= <single-gpio-range> [gpio-range-list] + single-gpio-range ::= <numeric-gpio-range> | <named-gpio-range> + numeric-gpio-range ::= + <pinctrl-phandle> <gpio-base> <pinctrl-base> <count> + named-gpio-range ::= <pinctrl-phandle> <gpio-base> '<0 0>' + pinctrl-phandle : phandle to pin controller node + gpio-base : Base GPIO ID in the GPIO controller + pinctrl-base : Base pinctrl pin ID in the pin controller + count : The number of GPIOs/pins in this range + +The "pin controller node" mentioned above must conform to the bindings +described in ../pinctrl/pinctrl-bindings.txt. + +In case named gpio ranges are used (ranges with both <pinctrl-base> and +<count> set to 0), the property gpio-ranges-group-names contains one string +for every single-gpio-range in gpio-ranges: + gpiorange-names-list ::= <gpiorange-name> [gpiorange-names-list] + gpiorange-name : Name of the pingroup associated to the GPIO range in + the respective pin controller. + +Elements of gpiorange-names-list corresponding to numeric ranges contain +the empty string. Elements of gpiorange-names-list corresponding to named +ranges contain the name of a pin group defined in the respective pin +controller. The number of pins/GPIOs in the range is the number of pins in +that pin group. + +Previous versions of this binding required all pin controller nodes that +were referenced by any gpio-ranges property to contain a property named +#gpio-range-cells with value <3>.

The procedure for garbage collection + * is different depending on whether a LEB as an index LEB (contains index + * nodes) or not. For non-index LEBs, garbage collection finds a LEB which + * contains a lot of dirty space (obsolete nodes), and copies the non-obsolete + * nodes to the journal, at which point the garbage-collected LEB is free to be + * reused. For index LEBs, garbage collection marks the non-obsolete index nodes + * dirty in the TNC, and after the next commit, the garbage-collected LEB is + * to be reused. Garbage collection will cause the number of dirty index nodes + * to grow, however sufficient space is reserved for the index to ensure the + * commit will never run out of space. + * + * Notes about dead watermark. At current UBIFS implementation we assume that + * LEBs which have less than @c->dead_wm bytes of free + dirty space are full + * and not worth garbage-collecting. The dead watermark is one min. I/O unit + * size, or min. UBIFS node size, depending on what is greater. Indeed, UBIFS + * Garbage Collector has to synchronize the GC head's write buffer before + * returning, so this is about wasting one min. I/O unit. However, UBIFS GC can + * actually reclaim even very small pieces of dirty space by garbage collecting + * enough dirty LEBs, but we do not bother doing this at this implementation. + * + * Notes about dark watermark. The results of GC work depends on how big are + * the UBIFS nodes GC deals with. Large nodes make GC waste more space. Indeed, + * if GC move data from LEB A to LEB B and nodes in LEB A are large, GC would + * have to waste large pieces of free space at the end of LEB B, because nodes + * from LEB A would not fit. And the worst situation is when all nodes are of + * maximum size. So dark watermark is the amount of free + dirty space in LEB + * which are guaranteed to be reclaimable. If LEB has less space, the GC might + * be unable to reclaim it. So, LEBs with free + dirty greater than dark + * watermark are "good" LEBs from GC's point of few.
