   How to create a bootable #AlpineLinux SD-card for VisionFive2 #RISCV:

   1) Partition the card. In this example I use /dev/sde. WARNING: Make sure you have the right device.

   doas parted /dev/sde --script mklabel gpt \
   mkpart primary 2MiB 4MiB set 1 bios_grub on \
   mkpart primary 4MiB 6MiB \
   mkpart primary 6MiB 100% set 3 boot on

     2) Create vfat filesystem on 3rd partition:

     doas mkfs.vfat /dev/sde3

     3) Mount the boot partition and extract Alpine tarball:

     doas mount /dev/sde3 /mnt
     curl -s https://dl-cdn.alpinelinux.org/alpine/v3.21/releases/riscv64/alpine-uboot-3.21.1-riscv64.tar.gz | doas tar -C /mnt -zxv

     4) Install U-Boot

     Write SPL to partition 1 and ITB to partition 2:

     doas dd if=/mnt/u-boot/starfive_visionfive2/u-boot-spl.bin.normal.out of=/dev/sde1
     doas dd if=/mnt/u-boot/starfive_visionfive2/u-boot.itb of=/dev/sde2

     5) Unmount the SD card and boot it.

     doas umount /mnt

     You should be able to see it boot from a debug UART

     @ncopa Maybe this should be in the wiki or something like install.txt file in https://dl-cdn.alpinelinux.org/alpine/v3.21/releases/riscv64/ ?
     
     Meanwhile I reused the script at https://arvanta.net/alpine/alpine-on-visionfive/ as a base because I didn't want some kind of installer dance as I don't have a spare eMMC or M.2 SSD (although I guess the installer could be booted from USB).

     The very first thing with this board is set the pins to SDIO mode ;-) Figure 4-10 in https://doc-en.rvspace.org/VisionFive2/PDF/VisionFive2_QSG.pdf

     @jarkko it is the only board I know that runs nicely with vanilla 6.12 kernel, which is also why we officially can support it

     @ncopa It's really my recommended board for testing RISC-V kernel. And the reason for this is that it is aging ;-) Also BuildRoot upstream boots it nicely.

     @ncopa Also not sure if stock boards have OpenSBI+u-boot flashed but that allows to skip flashing u-boot to SD/eMMC (and NVMe when u-boot is properly configured).
     
     So in the installer case just using one partition that u-boot can read (fat/ext3/ext4) is fine.
