This series few other patch series are awaiting response from
long time. In particular without this series many of the platforms
will _not_ work out-of-the box with x16 NAND device. Hence,
please give these patches a look and accept them if all okay.

Also, another series which has simple changes and clean-up is
awaiting acceptance from long.
[PATCH v2 0/7] mtd: nand: omap: clean up of omap_elm and omap_gpmc driver

This all will save some effort in resolving merge conflicts and rebases,
while moving forward with new patches.


with regards, pekon

>[PATCH v2 1/4]:
>  - dropped NAND_BUSWIDTH_AUTO, instead using CONFIG_SYS_NAND_ONFI_DETECTION

>[PATCH 2/4]: enable NAND_BUSWIDTH_AUTO feature in omap_nand.c
>[PATCH 3/4]: cleaning of GPMC configs for NAND and NOR
