Thanks for your response. Yet I could not find CONFIG_ options in U-Boot
equivalent to the atmel_nand options in the kernel. It seems like the U-Boot
NAND writes and the kernel NAND writes (when CONFIG_MTD_NAND_ATMEL is
selected) will use different logic for ECC and OOB layout.

Should the U-Boot "nand write.jffs2" command be avoided with AT91 targets
using post-2.6.27 kernels? Or are there U-Boot CONFIG_ options compatible
with the atmel_nand options in the current kernels?
