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()) - First version: v5 fit: Support compression for non-kernel components (e.g. FDT) - Changes for v2: - Changed from only supporting compressed FDTs to supporting all non-kernel image node types. - Changes for v3: - Fixed up some debug output that was still written for v1. - Fixed a mistake with handling FIT_LOAD_OPTIONAL_NON_ZERO when 'load' was 0 (i.e. unset). - Added compression test case to the test_fit pytest. - No changes for v4 - No changes for v5 fit: Support compat string property in configuration node - No changes for v2 - No changes for v3 - Changes for v4: - Added documentation for compatible string in config node. - Added example .its file for compressed FDT with compat string in config node. - No changes for v5
