[PATCH v2 0/2] mtd: nand: rework nand_ecc_ctrl interface for OOB

[Brian Norris]

Hello again,

This is v2 of my patches to change the nand_chip and nand_ecc_ctrl interfaces
so that the nand_ecc_ctrl functions have information about whether the higher
layers actually need OOB data to be read/written from/to the NAND device. Per
some suggestions I have received, I have settled on using a boolean 'use_oob'
argument that tells the callee function whether the calling function is using
chip->oob_poi for OOB data.

Please refer to previous communications for other details.

Similar notes from last time:

I could not compile all the affected drivers, since some required ARCH-specific
builds that I am not familiar with.

Artem: can you perform your regular compile tests? I compile-tested as many as
I could.

Others: if you care about your driver, please compile test and review to be
sure I'm doing things safely for you. Because most in-kernel drivers seem to be
perfecly happy using nand_chip.oob_poi for OOB data unconditionally, I have not
struggled to port most of them to take advantage of this full change. However,
some developers have noted that certain drivers could benefit from utilizing
this 'use_oob' parameter. Fell free to write/submit/review any code on top of
these patches, assuming they are eventually accepted.

Thanks for reviewing!

Brian
