MX51EVK: UART does not print out the early information
The early bootup information is not print out due to the UART pin iomux not set up correctly before board_init Add the board_early_init_f function and enable the CONFIG_BOARD_EARLY_INIT_F. Move the UART pin setting from board_init to board_early_init_f function. This patch also move the FEC pin iomux setup to the board_early_init_f. Signed-off-by: Jason Liu <r64343@freescale.com>
