Hi,

The command ext2load do not work on the OMAP3 EVM.

The command line is:
# ext2load mmc 0:2 0x82000000 /boot/uImage

The error is:
ext2fs_devread() read error - block

After reading the u-boot source code, I see that the function
mmc_bread() in file drivers/mmc/omap3_mmc.c do not return the good value.

So I apply this small patch to fix the problem

Best regards,

Mickael LANOE
