Sidequest: Install u-boot-menu

Don't be like me and reboot without configuring u-boot-menu. Although the defaults make sense for most people, in my case I lost access to the serial console (because that custom config needed to be re-done), and the default delay was not enough to choose a backup kernel. In consfigurator notation:

  (on-change
      (file:has-content "/etc/u-boot-menu/conf.d/reform.conf"
        '("U_BOOT_TIMEOUT=50"
          "U_BOOT_PARAMETERS=\"ro no_console_suspend cryptomgr.notests \\${bootargs} console=ttyS2,1500000 keep_bootcon console=tty1\""))
    (cmd:single "u-boot-update"))

The panel, alive.

• Thanks to a hint from joschc (and a bit of luck) I realized the
  issue I filed was nonsense. Yay?

• The panel driver is not added by the rk3588 patches (since the build process applies all the patches, this is not a problem for building from reform-debian-packages).

• After applying the two patches in reform-debian-packages/linux/patches6.15/imx8mp-mnt-pocket-reform/pocket-panel, the patched 6.16 kernel boots, and seems to work, including the panel.

• The updated source is on branch reform-patches at

  https://salsa.debian.org/bremner/collabora-rockchip-3588

• Unsurprisingly hibernate is not working out of the box with 6.16. My next mission is to apply the recommended pci-reset patches on top of 6.16.
