      Fix ext2/ext4 filesystem accesses beyond 2TiB · 04735e9c
      Frederic Leroy authored
      
      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.
