payloads/external/SeaBIOS: Allow setting buffers below 0xC0000
Add the option to coreboot to set the SeaBIOS buffers below 0xC0000. This is a requirement on the Intel Rangeley processor because it is designed so that only the processor can write the higher memory areas. This prevents USB and SATA from bus-mastering into the buffers when they're set in the typical 0xE0000 area. This will be set to Y unless defaulted to N by the mainboard or chipset. Push the SeaBIOS buffers down to 0x90000 segment for Mohon Peak Change-Id: I15638605d1c66a2277d4b852796db89978551a34 Signed-off-by: Martin Roth <martin.roth@se-eng.com> Reviewed-on: http://review.coreboot.org/6364 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Edward O'Callaghan <eocallaghan@alterapraxis.com>
