[U-Boot] [PATCH 2/2] fat: replace LINEAR_PREFETCH_SIZE with PREFETCH_BLOCKS
by Sergei Shtylyov 01 Oct '11

Currently in do_fat_read() when reading FAT sectors, we have to divide down LINEAR_PREFETCH_SIZE by the sector size, whereas it's defined as 2 sectors worth of bytes.

[U-Boot] [PATCH 1/2] fat: root directory cluster only makes sense for FAT32
by Sergei Shtylyov 01 Oct '11

01 Oct '11

The root directory cluster field only exists in a FAT32 boot sector, so the 'root_cluster' variable in do_fat_read() contains garbage in case of FAT12/16. Make it contain 0 instead as this is what is passed to get_vfatname() in that case anyway.

[U-Boot] [PATCH 2/2] fat: cannot compare bytes and sectors
by Sergei Shtylyov 01 Oct '11

01 Oct '11

The code multiples the FAT size in sectors by the sector size and then tries to compare that to the number of sectors in the 'getsize' variable. While fixing this, also change the initial value of 'getsize' as the division of FATBUFSIZE by the sector size gets us FATBUFBLOCKS.
