2013-05-10fs/ext4: Support device block sizes != 512 bytesEgbert Eich
The 512 byte block size was hard coded in the ext4 file systems. Large harddisks today support bigger block sizes typically 4096 bytes. This patch removes this limitation. Signed-off-by: Egbert Eich <eich@suse.com>

2012-10-29fs: separate CONFIG_FS_{FAT, EXT4} from CONFIG_CMD_{FAT, EXT*}Stephen Warren
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.

2012-10-03ext4: Rename block group descriptor table from gd to bgdSimon Glass
On x86 machines gd is unfortunately a #define, so we should avoid using gd for anything. This patch changes uses of gd to bgd so that ext4fs can be used on x86. A better fix would be to remove the #define in x86, but I'm not sure how to do that. Signed-off-by: Simon Glass <sjg@chromium.org>
2012-09-20ext4: cache-align buffers so the invalidation worksStephen Warren
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>
