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

Heya, Heinrich.

That device in the by-name seems to get created by
/usr/lib/udev/rules.d/60-persistent-storage-mtd.rules (from package
udev):

# do not edit this file, it will be overwritten on update

# persistent storage links: /dev/mtd/by-name

ACTION=="remove", GOTO="persistent_storage_mtd_end"
SUBSYSTEM!="mtd", GOTO="persistent_storage_mtd_end"
KERNEL!="mtd[0-9]*", GOTO="persistent_storage_mtd_end"
KERNEL=="mtd[0-9]*ro", GOTO="persistent_storage_mtd_end"

ATTR{name}=="?*", SYMLINK+="mtd/by-name/$attr{name}"

LABEL="persistent_storage_mtd_end"

Maybe I am getting the device mapping because I am running a 6.8.0-rc3
kernel I compiled myself?  I will reboot into the Ubuntu 6.5.0.14.14.1
kernel and check.

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
