The MT29F1G08ABAFAWP-ITE:F chip has 2048 byte pages and requires a minimum ECC strength of 8-bits. Allow for this combination of requirements using the marvell_nand controller.
Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz> --- I've tried to follow the recommended AN-379 from Marvell. They do seem to have information that covers this particular set of chip requirements.
As discussed I don't think my particular configuration will be supported with this change due to the conflict with the on-die ECC. But this may be useful for others so I've left it in.
Changes in v2: - update as suggested by miquel
