> Subject: [PATCH v2 03/11] imx: tpc70: Add board_boot_order() to distinguish
> between eMMC and SD boot
>
> The TPC70 can boot from SD card (debug/development) and eMMC
> (production).
> The board_boot_order() function provides a run time check for the device
> from which one wants to boot (it is selected by GPIO pins setup).
>
> Moreover, a fallback to SD card is provided if the detection is not possible
> or
> working properly.
