coreboot build errors:

                           ^
In file included from src/northbridge/amd/amdfam10/misc_control.c:34:0:
src/include/pc80/mc146818rtc.h:176:13: note: previous declaration of 'get_option' was here
 enum cb_err get_option(void *dest, const char *name);

Ping tpearson about this.

Also ping him about the fact that there isn't actually an option to
enable or disable native graphics initialization, but that the option
MAINBOARD_HAS_NATIVE_VGA_INIT_TEXTMODECFG is in fact available and set to Y in the
Kconfig file. I think this is probably since there isn't even an option
ROM available for the machine, so it's pointless to offer the setting.
