[PATCH 0/4] mtd: rawnand: sunxi: Fixes user data length for H6

[Richard Genoud]

This series introduces the correct usage of user data length for
H6/H616.
If the older SoCs must use a fixed value of 4 user data bytes for each
ECC step, the H6 can have a different value for each step.

In the first round, the behavior was kept as the one used by A10 when in
fact the images in the wild with the vendor kernel are using a different
layout.

The 3rd patch enables using variable user data length for H6/H616.
All other patches are fixes/code cleaning

A similar series is under review for Linux:
