This patch also includes 2 targets. One is the target that can be
programmed into the SPI NOR flash and a 2nd target "xxx-ram" is
added to support loading and booting via an already running U-Boot
version. This allows easy development and testing without the
need to flash the image each time.

do you plan to implement something? Otherwise you could drop those
functions and if you don't enable CONFIG_BOARD_EARLY_INIT_F and
CONFIG_DEBUG_UART_BOARD_INIT.
I'm currently working on some other MUX setup (etc) here for this
board. So its very likely that something will be added. But you
are right, DEBUG_UART_BOARD_INIT can very likely be dropped.
Thanks,
Stefan
