Subject: [PATCH v0 0/2] mtd: nand: allow unconventional NAND layouts

Currently validity checks in nand_scan_tail only allow NAND layouts with
evenly sized chunks. This results in controllers which use
unconventional layouts to fail these checks. To pass these checks
the marvell_nand driver would incorrectly read pages (leaving out the
unevenly sized chunk).

Relax this check and remove the change which modifies the layouts
resulting in errounous read/writes.

  Revert "mtd: rawnand: marvell: fix layouts"
  mtd: nand: relax ECC parameter validation check
