-;;; 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

+;;;  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.
