Subject: [PATCH v2 0/2] mtd: nand: introduce NAND_ROW_ADDR_3 flag and improve Denali driver

Currently, Denali NAND driver always expects 3 row address cycle
devices because the driver init code hard-code the register setting.
I will fix it in 2/2.

Many drivers check chip->chipsize if the third row address cycle
is needed or not.  This is not nice because 32MB, 128MB are
magic numbers.  nand_scan_ident can decide it and provide a
driver-friendly flag.

1/2 is touching verious drivers.
I hope Acked-by from driver maintainers if this change looks good.


Changes in v2:
 - Fix build error

Masahiro Yamada (2):
  mtd: nand: introduce NAND_ROW_ADDR_3 flag
  mtd: nand: denali: support two row address cycle devices
