* Consolidate bool typeYork Sun2013-04-01-6/+4
| | | | | | | | | | | | | 'bool' is defined in random places. This patch consolidates them into a single header file include/linux/types.h, using stdbool.h introduced in C99. All other #define, typedef and enum are removed. They are all consistent with true = 1, false = 0. Replace FALSE, False with false. Replace TRUE, True with true. Skip *.py, *.php, lib/* files.

Officially supported u-boot toolchains (eldk-5.[12].x) generate calls to __aeabi_uldivmod(), which is niether defined in the toolchain libs nor u-boot source tree.

* fs: rename fsload command to loadStephen Warren2012-11-04-1/+1
| | | | | | | | | | | When the generic filesystem load command "fsload" was written, I felt that "load" was too generic of a name for it, since many other similar commands already existed. However, it turns out that there is already an "fsload" command, so that name cannot be used. Rename the new "fsload" to plain "load" to avoid the conflict.

* fs: fix number base behaviour change in fatload/ext*loadStephen Warren2012-11-04-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Commit 045fa1e "fs: add filesystem switch libary, implement ls and fsload commands" unified the implementation of fatload and ext*load with the new command fsload. However, this altered the interpretation of command-line numbers from always being base-16, to requiring a "0x" prefix for base-16 numbers. Enhance do_fsload() to allow commands to specify which base to use. Use base 0, thus requiring a "0x" prefix for the new fsload command. This feels much cleaner than assuming base 16. Use base 16 for the pre-existing fatload and ext*load to prevent a change in behaviour. Use base 16 exclusively for the loadaddr environment variable, since that variable is interpreted in multiple places, so we don't want the behaviour to change. Update command help text to make it clear where numbers are assumed to be hex, and where an explicit "0x" prefix is required.

* fs: fix do_fsload() handling of optional argumentsStephen Warren2012-11-04-3/+7

Cater for the situation where argv[2] is not provided. Enhance both do_fsload() and do_ls() to check the maximum number of arguments too. While this check would typically be implemented via U_BOOT_CMD()'s max_args parameter, if these functions are called directly, then that check won't exist. Finally, alter do_ls() to check (argc >= 4) rather than (argc == 4) so that if the function is enhanced to allow extra arguments in the future, this test won't need to be changed at that time.

* fs: separate CONFIG_FS_{FAT, EXT4} from CONFIG_CMD_{FAT, EXT*}Stephen Warren2012-10-29-11/+8
| | | | | | | | | | | | | | | | | | This makes the FAT and ext4 filesystem implementations build if CONFIG_FS_{FAT,EXT4} are defined, rather than basing the build on whether CONFIG_CMD_{FAT,EXT*} are defined. This will allow the filesystems to be built separately from the filesystem-specific commands that use them. This paves the way for the creation of filesystem-generic commands that used the filesystems, without requiring the filesystem- specific commands. Minor documentation changes are made for this change. The new config options are automatically selected by the old config options to retain backwards-compatibility.

Equally, future DM rework will make the concept of partition number harder to pass around.

* fs: Add a Coreboot Filesystem (CBFS) driver and commandsGabe Black2012-10-22-0/+383
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds CBFS support and some commands to use it to u-boot. These commands are: cbfsinit - Initialize CBFS support and pull all metadata into RAM. The end of the ROM is an optional parameter which defaults to the standard 0xffffffff and can be used to support multiple CBFSes in a system. The last one set up with cbfsinit is the one that will be used. cbfsinfo - Print information from the CBFS header. cbfsls - Print out the size, type, and name of all the files in the current CBFS. Recognized types are translated into symbolic names. cbfsload - Load a file from CBFS into memory. Like the similar command for fat filesystems, you can optionally provide a maximum size. Support for CBFS is compiled in when the CONFIG_CMD_CBFS option is specified. The CBFS driver can also be used programmatically from within u-boot. If u-boot needs something out of CBFS very early before the heap is configured, it won't be able to use the normal CBFS support which caches some information in memory it allocates from the heap. The cbfs_file_find_uncached function searches a CBFS instance without touching the heap.

* fs: fat: Fix mkcksum() function parametersMarek Vasut2012-10-17-9/+13
| | | | | | | | | | | | | | | | | | | | The mkcksum() function now takes one parameter, the pointer to 11-byte wide character array, which it then operates on. Currently, the function is wrongly passed (dir_entry)->name, which is only 8-byte wide character array. Though by further inspecting the dir_entry structure, it can be noticed that the name[8] entry is immediatelly followed by ext[3] entry. Thus, name[8] and ext[3] in the dir_entry structure actually work as this 11-byte wide array since they're placed right next to each other by current compiler behavior. Depending on this is obviously wrong, thus fix this by correctly passing both (dir_entry)->name and (dir_entry)->ext to the mkcksum() function and adjust the function appropriately.

* FAT: check for partition 0 not 1 for whole-disk fsStephen Warren2012-10-08-1/+1
| | | | | | | | | | | | | | | | | | | | | The recent switch to use get_device_and_partition() from do_fat_ls() broke the ability to access a FAT filesystem directly on a whole device; FAT only works within a partition on a device. This change makes e.g. "fatls mmc 0:0" work; explicitly requesting partition ID 0 is something that get_device_and_partition() fully supports. However, fat_register_device() expects partition ID 1 to be used in the full-disk case; partition ID 1 was previously implicitly specified when the user didn't actually specify a partition ID. Update fat_register_device() to expect the correct ID. This change does imply that if a user explicitly executes "fatls mmc 0:1" then this will fail, and may be a change in behaviour. Note that this still prevents "fatls mmc 0:auto" from working. The next patch will fix that. Signed-off-by: Stephen Warren <swarren@nvidia.com>

| * ext4: cache-align buffers so the invalidation worksStephen Warren2012-09-20-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DMA buffer cache invalidation requires that buffers have cache-aligned buffer locations and sizes. Use memalign() and ALLOC_CACHE_ALIGN_BUFFER() to ensure this. On Tegra at least, without this fix, the following fail commands fail in u-boot-master/ext4, but succeeded at the branch's branch point in u-boot/master. With this fix, the commands work again: ext2ls mmc 0:1 / ext2load mmc 0:1 /boot/zImage Cc: Uma Shankar <uma.shankar@samsung.com> Cc: Manjunatha C Achar <a.manjunatha@samsung.com> Cc: Iqbal Shareef <iqbal.ams@samsung.com> Cc: Hakgoo Lee <goodguy.lee@samsung.com> Cc: Wolfgang Denk <wd@denx.de> Cc: Tom Rini <trini@ti.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
