Hi Tony,
These are some of the issues I found while testing v3.17-rc3.
- Wrong ECC scheme used for am43x GP and EPOS evm. We need to use
BCH16 instead of BCH8.
Thanks for updating ECC scheme for AM43x EVM boards.
Just for background history, BCH16 ECC scheme was not in
mainline when AM43xx NAND DTS patches were accepted. So to
avoid any inter-dependency of patches, BCH8 was used instead.

ARM: dts: am43xx: add support for parallel NAND flash

mtd: nand: omap: add support for BCH16_ECC - NAND driver updates
CommitDate: 21 May 2014
For the record, boot-loader (u-boot SPL) on AM43x-EPOS and
AM437x-GP EVM boards should be flashed in BCH16 ECC scheme
as NAND device present on this boards has
- page-size=4KiB
- OOB-size=224B
So ROM code expects BCH16 ECC scheme to load first boot-loader(SPL).
with regards, pekon
