[Bug 2052693] Re: u-boot-starfive does not contain a postinst script to update the board after package installation

Heya, Heinrich...  sorry, I thought I'd shown the rule in
https://bugs.launchpad.net/ubuntu/+source/u-boot/+bug/2052693/comments/2

Here we go:

$ grep -GHrn by-name /lib/udev
/lib/udev/rules.d/60-persistent-storage-mtd.rules:3:# persistent storage links: /dev/mtd/by-name
/lib/udev/rules.d/60-persistent-storage-mtd.rules:10:ATTR{name}=="?*", SYMLINK+="mtd/by-name/$attr{name}"

$ apt-file search /lib/udev/rules.d/60-persistent-storage-mtd.rules
udev: /usr/lib/udev/rules.d/60-persistent-storage-mtd.rules

$ apt policy udev
udev:

Title:
  u-boot-starfive does not contain a postinst script to update the board
  after package installation

Status in u-boot package in Ubuntu:
  New

Bug description:
  u-boot-starfive distributes updates to SPL and  U-Boot, but it does
  not flash them to the board.  I think it would be useful if it
  followed the pattern of u-boot-sifive and included a postinst script
  to update the board.

  The script could look something like this.  NB:  I only have access to
  a StarFive VisionFive 2 v1.3B board.  Not sure if the other revisions
  are compatible with the SPL and U-Boot images in the u-boot-starfive
  package:

  #!/bin/sh

  ##

  set -e

  case "$1" in
      configure)
          target=""
          if grep -q '^StarFive VisionFive 2 v1.3B$' /sys/firmware/devicetree/base/model; then
              target="starfive_visionfive2"
          fi
          if [ -n "$target" ] && [ -e /dev/mtd/by-name/spl ] && [ -e /dev/mtd/by-name/uboot ]; then
              flashcp -v /usr/lib/u-boot/$target/u-boot-spl.bin.normal.out /dev/mtd/by-name/spl
              flashcp -v /usr/lib/u-boot/$target/u-boot.itb /dev/mtd/by-name/uboot
          fi
          ;;
  esac

  exit 0
