[U-Boot] [PATCH] FAT on non standard sector size devices

[Igor Luri]

Hi all!

There are USB devices with sector size different than 512 bytes. In
fact, I have one with 2048 bytes per sector:

scsi0 : SCSI emulation for USB Mass Storage devices
  Vendor: ChipsBnk  Model: Flash Disk        Rev: 4.00
  Type:   Direct-Access                      ANSI SCSI revision: 02
Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0
SCSI device sda: 129124 2048-byte hdwr sectors (264 MB)
sda: Write Protect is off
Partition check:
 sda: sda1 sda2 sda3 sda4

U-boot FAT filesystem code supposes that sector size is always 512
bytes, consecuently fatload and fatls commands ends up with a
segmentation fault.

Attached patches adds FAT support on devices with sector size up to 8192
bytes.

I have only tested on our custom board with u-boot 1.1.6 version. I
would aprpeciate if someone could test this patch on latest version.

Thanks.
