[U-Boot] [PATCH v2] Fix ext2/ext4 filesystem accesses beyond 2TiB

Frédéric Leroy
2013-06-26T16:11:25Z

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.

Changes in v2 :
- Fix warning in disk/part_efi.c by Sascha Silbe
- Fix lines over 80 characters
- Move LBAFu to LBAFU to avoid camel case
