[U-Boot] cannot load file from ext2 partition on OMAP3 evm

Hi,
The command ext2load does 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 does not return the good value.
So I apply this small patch to fix the problem
Best regards,
Mickael LANOE
