[U-Boot] [PATCH 0/3] davinci: spl: select boot device based on boot pin cfg

[Fabien Parent]

Right now the SPL is trying to load u-boot based on defines, i.e. one has to
define CONFIG_SPL_NAND_SIMPLE to boot from NAND, or CONFIG_SPL_SPI_LOAD to boot
from SPI FLASH, etc...
This prevent us from having a single SPL image that is able to boot from all
media, and one need to build an image for each medium. This patchset is
replacing the #ifdef that select the boot medium by reading the value of the
boot pins (via the BOOTCFG register).

Now a single SPL image will be able to read from the boot pin to know
which device should be used to load u-boot.

This patchset is also enable SPL's MMC boot for the OMAPL138-LCDK in order
to have one image that is able to boot from MMC and NAND.

  davinci: spl: use bootcfg to select boot device
  omapl138_lcdk: enable SPL MMC support
  omapl138_lcdk: remove empty ifdef block
