[U-Boot] [PATCH] am33xx, spl, siemens: enable debug uart output again
a6b541b090: TI ARMv7: Don't use GD before crt0.S has set it moves the init of the debug uart at the very end of SPL code. Enable it for the siemens board earlier, as they print ddr settings ... all debug output before board_init_r() is here currently useless. Maybe we must rework this globally?
