* Fix ext2/ext4 filesystem accesses beyond 2TiBFrederic Leroy2013-07-151-1/+1
| | | | | | | | | | | | | | | | | With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives We now use lbaint_t for partition offset to reflect the lbaint_t change, and access partitions beyond or crossing the 2.1TiB limit. This required changes to signature of ext4fs_devread(), and type of all variables relatives to block sector. ext2/ext4 fs uses logical block represented by a 32 bit value. Logical block is a multiple of device block sector. To avoid overflow problem when calling ext4fs_devread(), we need to cast the sector parameter. Signed-off-by: Frédéric Leroy <fredo@starox.org>
* fs/ext4: Support device block sizes != 512 bytesEgbert Eich2013-05-101-0/+1
| | | | | | | | | 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>
* fs: Move ls and read methods into ext4, fatSimon Glass2013-03-041-0/+3
| | | | | | | | | It doesn't make a lot of sense to have these methods in fs.c. They are filesystem-specific, not generic code. Add each to the relevant filesystem and remove the associated #ifdefs in fs.c. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@ti.com>
* fs: separate CONFIG_FS_{FAT, EXT4} from CONFIG_CMD_{FAT, EXT*}Stephen Warren2012-10-291-1/+1
| | | | | | | | | | | | | | | | | | 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.

* ext4: Rename block group descriptor table from gd to bgdSimon Glass2012-10-031-1/+1
| | | | | | | | | | | 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>
* cmd_extX: use common get_device_and_partition functionRob Herring2012-09-251-2/+1
| | | | | | | | 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: remove init_fs/deinit_fsRob Herring2012-09-251-2/+0
| | | | | | | There's no real need to expose this and it can be removed by using a static allocation. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
