[U-Boot] [PATCH v6 0/3] fit: Image node compression

[Julius Werner]

This patch series adds compression support for non-kernel FIT image
nodes (e.g. FDTs). The first patch is a preparatory refactoring, the
second adds the compression support itself, and the third adds a new
feature to compatible string matching that allows it to be useful
with compressed FDTs.

Sandbox-tested with FIT images with and without compressed FDTs, with
and without overlays, in both compatible string matching and direct
config selection modes. Also expanded the test_fit pytest to include a
case with compressed kernel, FDT and ramdisk.

Julius Werner (3):
  common: Move bootm_decomp_image() to image.c (as image_decomp())
  fit: Support compression for non-kernel components (e.g. FDT)
  fit: Support compat string property in configuration node

- Changes for v6
  - Fixed test_fit.py (had a printf() without a newline)
- Changes for v5
  - Added first patch to support tools-only_defconfig (which doesn't
    build bootm.c)
- Changes for v4
  - Added documentation
- Changes for v3
  - Added tests, fixed a few minor issues
- Changes for v2
  - Changed to support all non-kernel image types (not just FDT)
