This patchset is aimed at : - fixing 5 glitches in the driver - add several new functions
The added functions are : - add block erase capability - add write page capability - add powerdown and powerup - add multiple floor support - add ECC support - add docg3 modes support - add protection support (DPS areas)
The ECC part should especially be reviewed by Ivan and Mike, as this is their work (patch "add ECC correction code").
Since V1, Ivan's and Mike's comments have been taken into account, and nandtest/nanddump/nandwrite testing has been done, with and without bitflipped data.
Moreover, 3 new patches have been added: - fix reading oob+data without correction This was triggered by the bitflipped pages tests, and fixes cases where we want to read corrupted data. - add docg3 modes support This actually fixes the read part, as we now read in "normal" mode by default rather than in "reliable" mode. This is mandatory for nandtest to work, because of the "even/odd pages logical AND". - add protection support This is an evolution to be able to access the whole chip in protected chips, as they are in smartphones.
Happy review.
