coreboot build errors: In file included from src/northbridge/amd/amdfam10/misc_control.c:35:0: src/include/option.h:13:27: error: static declaration of 'get_option' follows non-static declaration static inline enum cb_err get_option(void *dest, const char *name) ^ 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.
