Make first step in DT/DM migration. Enable OF_CONTROL only for the main U-Boot image for now. Remove mmc_init_main() because board_mmc_init() is not called when DM_MMC is enabled. DM_MMC requires DM_GPIO for card-detect to work. That in turn makes gpio request mandatory. Add code to request/free gpios in platform code. MMC devices are now numbered according to DT. The SD card is 1, and eMMC is 2. Account for that in board_mmc_get_env_dev(), BOOT_TARGET_DEVICES, and has_emmc(). DM_MMC requires BLK. However, the (BLK && !DM_USB) combination disables USB_STORAGE. Enable DM_USB to preserve USB functionality. Add also DM_REGULATORS for the USB power controller. This allows us to drop board_ehci_hcd_init() and setup_usb(). Runtime selection of DT is necessary because of the i.MX6QD vs i.MX6SDL incompatibility. DT selection does not rely on GPIOs, since DM_GPIO depends on DT. Instead, we take one "fully featured" DT of each variant. That should be enough to boot from both SD card and eMMC. Since we don't select the exact DT, override the generic show_board_info() that shows the selected DT 'model' field.

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.
