Subject: [PATCH v1 0/5] refactoring and fix for Meson NAND

Hello,

this patchset adds one fix and several refactoring patches. First patch
is the most important - it fixes unstable behaviour of Meson driver, for
example random ECC errors during reads. I've tested this with mount/
unmount/read/write cases for JFFS2 and nanddump/nandwrite utlities on
AXG family (A113X SoC). Source of this update is old vendor's driver.

Other patches are refactoring and extra checks, not critical for this
driver's reliability.

Arseniy Krasnov (5):
  mtd: rawnand: meson: fix NAND access for read/write
  mtd: rawnand: meson: replace GENMASK() macro with define
  mtd: rawnand: meson: check buffer length
  mtd: rawnand: meson: clear OOB buffer before read
  mtd: rawnand: meson: remove unneeded bitwise OR with zeroes
