;;; VisionFive2 can boot from MMC1 (SPI flash) or MMC2 (SD card) selected
;;; by DIP switches MSEL[1:0], you may want boot from MMC2 to use the
;;; U-Boot from Guix System instead of the vendor U-Boot in MMC1. Before
;;; doing so, make sure you have a correct 'fdtfile' in the environment:
;;; With this image, VisionFive2 can boot from MMC1 (MicroSD card) with
;;; SDIO3.0 boot mode (RPIO_1:L, RGPIO_0:H -- see [1]), in this case the
;;; board will use U-Boot from Guix System instead of the vendor U-Boot.
;;; Booting from eMMC and NVME is still work-in-progress.
