* fdt: Add basic support for decoding GPIO definitionsSimon Glass2012-03-29-0/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds some support into fdtdec for reading GPIO definitions from the fdt. We permit up to FDT_GPIO_MAX GPIOs in the system. Each GPIO is of the form: gpio-function-name = <phandle gpio_num flags>; where: phandle is a pointer to the GPIO node gpio_num is the number of the GPIO (0 to 223) flags is a flag, as follows: bit meaning 0 0=polarity normal, 1=active low (inverted) An example is: enable-propounder-gpios = <&gpio 43 0>; which means that GPIO 43 is used to enable the propounder (setting the GPIO high), or that you can detect that the propounder is enabled by checking if the GPIO is high (the fdt does not indicate input/output). Two main functions are provided: fdtdec_decode_gpio() reads a GPIO property from an fdt node and decodes it into a structure. fdtdec_setup_gpio() sets up the GPIO by calling gpio_request for you. Both functions can cope with the property being missing, which is taken to mean that that GPIO function is not available or is not needed. [For reference, from Stephen Warren <swarren@nvidia.com>. It may be that we add this extra complexity later if needed: The correct way to parse such a GPIO property in general is: * Read the first cell. * Find the node referenced by the phandle (the controller). * Ensure property gpio-controller is present in the controller node. * Read property #gpio-cells from the controller node. * Extract #gpio-cells from the original property. * Keep processing more cells from the original property; there may be multiple GPIOs listed. According to the binding documentation in the Linux kernel, Samsung Exynos4 doesn't use this format, and while all other chips do have a flags cell, about 50% of the controllers indicate the cell is unused. ] Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>

| | | | | | | | | | | | Add a function to look up a property which is a phandle in a node, and another to read a fixed-length integer array from an fdt property.

* fdt: Tidy up a few fdtdec problemsSimon Glass2012-03-29-6/+16
| | | | | | | | | | | | | | | | This fixes five trivial issues in fdtdec.c: 1. fdtdec_get_is_enabled() doesn't really need a default value 2. The fdt must be word-aligned, since otherwise it will fail on ARM 3. The compat_names[] array is missing its first element. This is needed only because the first fdt_compat_id is defined to be invalid. 4. Added a header prototype for fdtdec_next_compatible() 5. Change fdtdec_next_alias() to only increment its 'upto' parameter on success, to make the display error messages in the caller easier.

* fdt: Add tests for fdtdecSimon Glass2012-03-29-0/+227

* fdt: Add fdtdec_find_aliases() to deal with alias nodesSimon Glass2012-03-29-0/+116
| | | | | | | | | | | | | | | | Stephen Warren pointed out that we should use nodes whether or not they have an alias in the /aliases section. The aliases section specifies the order so far as it can, but is not essential. Operating without alisses is useful when the enumerated order of nodes does not matter (admittedly rare in U-Boot). This is considerably more complex, and it is important to keep this complexity out of driver code. This patch creates a function fdtdec_find_aliases() which returns an ordered list of node offsets for a particular compatible ID, taking account of alias nodes.

* fdt: add decode helper librarySimon Glass2011-10-26-0/+148
| | | | | | | | | | | | | | | | | | This library provides useful functions to drivers which want to use the fdt to control their operation. Functions are provided to: - look up and enumerate a device type (for example assigning i2c bus 0, i2c bus 1, etc.) - decode basic types from the fdt, like addresses and integers While this library is not strictly necessary, it helps to minimise the changes to a driver, in order to make it work under fdt control. Less code is required, and so the barrier to switch drivers over is lower. Additional functions to read arrays and GPIOs could be made available here also.

* zlib: handle overflow while calculating available stream input sizeAnatolij Gustschin2011-10-17-0/+8
| | | | | | | | | | | | | | | | | | | | | If compressed data is located in sectors at the end of the flash and it's offset + input stream size > 0xFFFFFFFF, the uncompressing time is very long, since processing of the stream is done bytewise (and not blockwise) due to overflow in inflate_fast() while calculation and checking for enough input available. Check for this overflow condition and limit the available stream input size to the actually max. possible input size. This fixes the problem. The issue is easily reproduceable by placing a gziped bitmap in flash, e.g. at FFF80000, and running 'bmp' commands like 'bmp info FFF80000' or 'bmp display FFF80000'. The uncompressing can take up to 3 sec. whereas it should normaly take a fraction of a second. If the 'splashimage' environment variable points to this address, the booting time also increases significantly. Signed-off-by: Anatolij Gustschin <agust@denx.de>

* Add assert() for debug assertionsSimon Glass2011-09-10-5/+8
| | | | | | | | | | | | | | | assert() is like BUG_ON() but compiles to nothing unless DEBUG is defined. This is useful when a condition is an error but a board reset is unlikely to fix it, so it is better to soldier on in hope. Assertion failures should be caught during development/test. It turns out that assert() is defined separately in a few places in U-Boot with various meanings. This patch cleans up some of these. Build errors exposed by this change (and defining DEBUG) are also fixed in this patch. Signed-off-by: Simon Glass <sjg@chromium.org>

* libfdt: Implement property iteration functionsDavid Gibson2011-07-14-36/+97
| | | | | | | | | | | | | | | | | | | | | | | | | | | For ages, we've been talking about adding functions to libfdt to allow iteration through properties. So, finally, here are some. I got bogged down on this for a long time because I didn't want to expose offsets directly to properties to the callers. But without that, attempting to make reasonable iteration functions just became horrible. So eventually, I settled on an interface which does now expose property offsets. fdt_first_property_offset() and fdt_next_property_offset() are used to step through the offsets of the properties starting from a particularly node offset. The details of the property at each offset can then be retrieved with either fdt_get_property_by_offset() or fdt_getprop_by_offset() which have interfaces similar to fdt_get_property() and fdt_getprop() respectively. No explicit testcases are included, but we do use the new functions to reimplement the existing fdt_get_property() function.

* Support ePAPR compliant phandle propertiesDavid Gibson2011-07-14-6/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the Linux kernel, libfdt and dtc, when using flattened device trees encode a node's phandle into a property named "linux,phandle". The ePAPR specification, however - aiming as it is to not be a Linux specific spec - requires that phandles be encoded in a property named simply "phandle". This patch adds support for this newer approach to dtc and libfdt. Specifically: - fdt_get_phandle() will now return the correct phandle if it is supplied in either of these properties - fdt_node_offset_by_phandle() will correctly find a node with the given phandle encoded in either property. - By default, when auto-generating phandles, dtc will encode it into both properties for maximum compatibility. A new -H option allows either only old-style or only new-style properties to be generated. - If phandle properties are explicitly supplied in the dts file, dtc will not auto-generate ones in the alternate format. - If both properties are supplied, dtc will check that they have the same value. - Some existing testcases are updated to use a mix of old and new-style phandles, partially testing the changes. - A new phandle_format test further tests the libfdt support, and the -H option.

So split the single file up into the original file names, and merge non-essential changes back from the original tree (for some reason, style in code in a bunch of places was changed to U-Boot style even though this isn't "U-Boot" code).

Initially found that "ramdiskimage" and "preboot" collide modulus 347, causing "preboot" to be inserted at idx 190, "ramdiskimage" at idx 191. Previous to this fix when "preboot" is deleted, "ramdiskimage" is orphaned. Signed-off-by: Peter Barada <peter.barada@logicpd.com> Tested-by: Wolfgang Denk <wd@denx.de>

* asm-offsets: generate bd_t sizeMike Frysinger2011-01-09-0/+3
| | | | | | | | Some ports set up the board info structure at the same time as the global data structure, and largely keep them together. So generate a define for the board info struct too. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* env: re-add support for auto-completionMike Frysinger2011-01-09-0/+26
| | | | | | | Currently, only basic completion is supported (no globs), but this is what we had previously. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* hashtable: drop all non-reentrant versionsMike Frysinger2010-12-17-38/+2
| | | | | | | | | | | The non-reentrant versions of the hashtable functions operate on a single shared hashtable. So if two different people try using these funcs for two different purposes, they'll cause problems for the other. Avoid this by converting all existing hashtable consumers over to the reentrant versions and then punting the non-reentrant ones. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| | | | | | | The duplication of the do_reset prototype has gotten out of hand, and they're not all in sync. Unify them all in command.h. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>
