I'm working on a at91sam9m10ek, using latest origin/next.

The ecc-mode is "hardcoded" to NAND_ECC_HW in
arch/arm/mach-at91/at91sam9g45_devices.c. I've got the same -74 problem
when reading from the nand.

Barebox fails to read the environment, even if barebox has written it.
After changing the ecc mode to soft the env can be read and written
without problems.

I ported the atmel nand driver from linux-2.6.37, which had no
significant differences.

cheers, Marc
