Walter Lozano 6c3fbf3e45 mx6cuboxi: customize board_boot_order to access eMMC In SPL legacy code only one MMC device is created, based on BOOT_CFG register, which can be either SD or eMMC. In this context board_boot_order return always MMC1 when configure to boot from SD/eMMC. After switching to DM both SD and eMMC devices are created based on the information available on DT, but as board_boot_order only returns MMC1 is not possible to boot from eMMC. This patch customizes board_boot_order taking into account BOOT_CFG register to point to correct MMC1 / MMC2 device. Additionally, handle IO mux for the desired boot device.

How to use U-Boot on Solid-run mx6 Hummingboard and Cubox-i
-----------------------------------------------------------

- Build U-Boot for Hummingboard/Cubox-i:

$ make mrproper
$ make mx6cuboxi_defconfig
$ make

This will generate the SPL image called SPL and the u-boot.img.

- Flash the SPL image into the SD card:

sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync

- Flash the u-boot.img image into the SD card:

sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync

- Insert the SD card in the board, power it up and U-Boot messages should
come up.
