[PATCH 00/13] images: add barebox FIT image target

[Ahmad Fatoum]

The generic barebox-dt-2nd.img depends on the user to fish out
the correct device tree from arch/${SRCARCH}/dts and to instruct
the preceding boot stage to pass that device tree to the barebox image.

To make this easier, especially with an eye towards using this as a
coreboot payload, let's have the barebox build system produce a FIT
image combining barebox-dt-2nd.img and all the enabled device trees.

As this introduces a python3 and python3-libfdt dependency that wasn't
there before, this is only built by default if CONFIG_BOARD_GENERIC_FIT
is enabled or make barebox.fit is explicitly invoked.

Ahmad Fatoum (13):
  ARM: dts: add device trees for the QEMU Virt machine
  treewide: collect the name of all board device trees
  kbuild: collect available device trees in dtbs-list
  scripts: add new scripts_dtc target
  kbuild: restrict dtbs target to enabled DTs by default
  kbuild: improve make help description
  kbuild: allow dependency on any file in images/
  arch: maintain Linux kernel and mkimage ARCH mapping in Kconfig
  arch: make BOARD_GENERIC_DT a user-selectable option across archs
  images: add barebox FIT image target
  MAKEALL: rename target in symbols to more appropiate defconfig
  MAKEALL: add support for building arbitrary targets
  ci: container: add python3-libfdt dependency for barebox.fit
