| | | | | | | | | The device block descriptor (block_dev_desc_t) )shall be stored at ext4 early code (at ext4fs_set_blk_dev in this case) to be available for latter use (like put_ext4()).

* cmd_extX: use common get_device_and_partition functionRob Herring2012-09-25-19/+13
| | | | | | | | Convert ext2/4 load, ls, and write functions to use common device and partition parsing function. With the common function "dev:part" can come from the environment and a '-' can be used in that case. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
* ext4: cache-align buffers so the invalidation worksStephen Warren2012-09-20-2/+2
| | | | | | | | | | | | | | | | | | | | | 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>
