Grazvydas Ignotas 7a559c7882 omap: cleanup NAND platform data
omap_nand_platform_data fields 'options', 'gpio_irq', 'nand_setup' and
'dma_channel' are never referenced by the NAND driver, yet various
board files are initializing those fields. This is both incorrect and
confusing, so remove them. This allows to get rid of a global
variable in gpmc-nand.c.

This also corrects an issue where some boards are trying to pass NAND
16bit flag through .options, but the driver is using .devsize instead
and ignoring .options.

Finally, .dev_ready is treated as a flag by the driver, so make it bool
instead of a function pointer.

Sukumar Ghorai d5ce2b6592 omap3630: nand: fix device size to work in polled mode
zoom3 and 3630-sdp having the x16 nand device.
This patch configure gpmc as x16 and select the currect function in driver
for polled mode (without prefetch enable) transfer.

Adrian Hunter a3551f5b0c OMAP2/3: GPMC: put sync_clk value in picoseconds instead of nanoseconds
The calculations done with sync_clk are anyway in picoseconds
and switching to picoseconds allows sync_clk values that are
not a whole number of nanoseconds - which is sometimes the
case.

Sukumar Ghorai 2c01946c6b omap3 nand: cleanup virtual address usages
This patch removes direct reference of gpmc address from generic nand platform code.
Nand platform code now uses wrapper functions which are implemented in gpmc module.

stanley.miao 11e1ef2d10 omap: fix a gpmc nand problem
If gpmc_t isn't given, we don't need to set timing for gpmc, or it will cause
a Oops.

Vimal Singh 2f70a1e936 omap2/3/4: Introducing 'gpmc-nand.c' for GPMC specific NAND init
Introducing 'gpmc-nand.c' for GPMC specific NAND init.
For example: GPMC timing parameters and all.
This patch also migrates gpmc related calls from 'nand/omap2.c'
to 'gpmc-nand.c'.
