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

[Heinrich Schuchardt]

We have no control over the kernel or device-tree that the user uses.
The definitions of the MTD partitions might not match our device-tree.

/sys/class/mtd/mtd*/offset has the offsets of the MTD partitions. This
would need to be checked before flashing.

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
