The platform_quirk element in the platform data was used
to change the way the IRQ is triggered.  When set,
the EDGE_IRQ quirk would change the irqflags used
and treat edge trigger differently from the rest.

Instead of hiding this irq flag setting behind the quirk,
have the board files set the irq_trigger explicitly.

This will allow us to use standard irq DT definitions
later on.

The problem that the set timings code contains the call of Davinci
platform function davinci_aemif_setup_timing() which is not
accessible if kernel is built for another platform like Keystone.

The Keysone platform is going to use TI AEMIF driver.
If TI AEMIF is used we don't need to set timings and bus width.
It is done by AEMIF driver.

To get rid of davinci-nand driver dependency on aemif platform code
we moved aemif code to davinci platform.

The platform AEMIF code (aemif.c) has to be removed once Davinci
will be converted to DT and use ti-aemif.c driver.

Without this patch, da8xx_register_spi() registers the SPI board info,
the SPI controller, and sets its number of chipselect to the size of the
static spi_board_info array. This is bad because a SPI board info may
declare devices for different SPI buses, and because other code can also
call spi_register_board_info() (e.g. a daughter board might provide
additional SPI devices).

This patch removes the spi_register_board_info() call from
da8xx_register_spi(), renames this last one to da8xx_register_spi_bus()
to be more explicit, takes the number of chipselect as a function
parameter, and updates the impacted board-da8{3,5}0-evm.c, and
board-mityomapl138.c files accordingly. It also sets the SPI platform
data static, as it doesn't need to be exported.

This patch works with the following three flags from two headers (nand.h
and bbm.h):
  (1) NAND_USE_FLASH_BBT (nand.h)
  (2) NAND_USE_FLASH_BBT_NO_OOB (nand.h)
  (3) NAND_BBT_NO_OOB (bbm.h)

These flags are all related and interdependent, yet they were in
different headers. Flag (2) is simply the combination of (1) and (3) and
can be eliminated.

This patch accomplishes the following:
  * eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2))
  * move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h

It's important to note that because (1) and (3) are now both found in
bbm.h, they should NOT be used in the "nand_chip.options" field.

I removed a small section from the mtdnand DocBook because it referes to

DA850/OMAP-L138 EMAC driver uses random mac address instead of
a fixed one because the mac address is not stuffed into EMAC
platform data.

This patch provides a function which reads the mac address
stored in SPI flash (registered as MTD device) and populates the
EMAC platform data. The function which reads the mac address is
registered as a callback which gets called upon addition of MTD
device.

NOTE: In case the MAC address stored in SPI flash is erased, follow
the instructions at [1] to restore it.

c. Passed the da850evm_spi_notifier structure to register_mtd_user()
