PS2, Line 46: 		if (CONFIG(BOARD_GOOGLE_KINGLER_COMMON))
            : 			gpio_output(GPIO_EN_PP3300_SDBRDG_X, 1);
            : 		else
            : 			mtk_msdc_configure_sdcard();
I'm confused. for SDCARD_INIT,

BOARD_GOOGLE_KINGLER_COMMON = y,
 BOARD_GOOGLE_KRABBY_COMMON = n,

So what's the case people will have SDCARD_INIT but not CONFIG(BOARD_GOOGLE_KINGLER_COMMON) ?

If no designs will be using the internal SDCard (due to WiFi?), then it's more correct to just say

if (CONFIG(SDCARD_INIT)) {
   ...
   /* External SD Card connected via USB */
   gpio_output(GPIO_EN_PP3300_SDBRDG_X, 1);
 }
