Re: Milk-V Mars CM JH7110

My Milk-V Mars CM is no-wifi, 2GB RAM, no-eMMC.

It seems that, for Milk-V Mars CM, mmc1 must be disabled.

  % cat > w.dts
  #include "jh7110-milkv-mars.dts"
  / { model = "Milk-V Mars CM"; };
  &mmc1 { status = "disabled"; };
  ^D

  % cat > Makefile
  NETBSDSRCDIR = /somewhere/nb/src
  DTSGNUARCH = riscv
  DTSSUBDIR = starfive
  .include <bsd.dtb.mk>
  ^D

  % make w.dtb

U-Boot is preinstalled on SPI. At that prompt:

  StarFive #
  StarFive # fatls mmc 0:1
  StarFive # fatload mmc 0:1 ${kernel_addr_r} EFI/Boot/bootriscv64.efi
  StarFive # fatload mmc 0:1 ${fdt_addr_r} dtb/w.dtb
  StarFive # bootefi ${kernel_addr_r} ${fdt_addr_r}
