Hi Artem,

Thanks for your reply. I was finally able to resolve most of the
driver issues. The main problem turned out to be because the TI kernel
had issues in drivers/mtd/nand/omap2.c, where it forced ecc_opt to be
OMAP_ECC_HAMMING_CODE_HW, and it seems that this setting is buggy.
I've changed that to OMAP_ECC_HAMMING_CODE_DEFAULT and now everything
except for mtd_oobtest is passing (full log below). I'm able to flash
ubifs image on this and it appears to survive multiple boots. I have
not tested very thoroughly but it seems to be working.

Would I be correct in assuming that the mtd_oobtest failure can be
ignored since ubi does not use OOB?

Thanks,
jayakumar
