TI DaVinci: DM355: Config Cleanup and Update
This patch does the following
1) Enables the NAND driver which is now available.
2) Enables the 'CONFIG_MTD_DEVICE' as without this the
compilation will fail
3) We now have a safe place to store environment and defines
an offset where this can be stored. This offset value is such that it is after
the location where U-Boot is flashed using TI flash utilities.
4) Enables Bootdelay
5) Increases malloc() arena size. Manufacturers are coming out with
NAND with large blocks sizes of upto 1 MiB. It has been noticed that
as the block size of the NAND used is increased, if this particular
value is not increased, the NAND driver will output out of memory
errors.
