Hello,

this patchset adds support for 512B ECC step size for Meson NAND. Current
implementation only supports 1024B. There are two patches:

1) Update for device tree bindings to replace 'const' type of field
'nand-ecc-step-size' with 'enum' which contains 512 and 1024. Example
is also updated.

2) Update for Meson driver - new enum value for 512B ECC and reworked
ECC capabilities structure to support both 512B and 1024B ECC. By
default this driver uses 1024B ECC, 512B could be enabled in device
tree.
