However, the regex used also means we included commands that may have been built. On omap5_uevm this leads to a failure as we include the command from the do_tca642x command, and fail to link. The fix is to restrict our regex to only the i2c list parts.

Also, it supports max 8 chip-selects, which can be independently connected to any of the devices. But ROM code expects the boot-device to be connected to only chip-select[0]. Thus to resolve conflict between NOR and NAND boot. This patch: - combines NOR and NAND configs spread in board files to common gpmc_init() - configures GPMC based on boot-mode selected for SPL boot.
