Subject[RFC PATCH 00/10] Macronix ECC engine
Date
Hello all,

This series is not 100% stable yet but I believe it should be
sent out in order to help other people trying to use the ECC framework
with a SPI controller. Basically, Macronix ECC engine can be used as an
external engine (takes the data, proceeds to the calculations, writes
back the ECC bytes) or as a pipelined engine doing on-the-fly
calculations (which is very common in the raw NAND world).

In the device tree, the ECC engine should be described as a separated DT
node. Then:
* external case: the flash node should provide a nand-ecc-engine
property pointing to the ECC engine node.
* pipelined case: the flash node should provide a nand-ecc-engine
property pointing to the SPI controller, itself with another
nand-ecc-engine property pointing at the ECC engine node.

I will resubmit this later when I will be done validating the hardware
and the driver.

Cheers,
Miquèl
