    ARM: mxs: Receive r0 and r1 passed from BootROM · 7b8657e2
    Marek Vasut authored
    Make sure value in register r0 and r1 is preserved and passed to
    the board_init_ll() and mxs_common_spl_init() where it can be
    processed further. The value in r0 can be configured during the
    BootStream generation to arbitary value, r1 contains pointer to
    return value from CALL'd function.
    This patch also clears the value in r0 before returning to BootROM
    to make sure the BootROM is not confused by this value.
    Finally, this patch cleans up some comments in the start.S file.
