Much of the image-handling code predates the introduction of Kconfig and has quite a few #ifdefs in it. It also uses its own IMAGE_... defines to help reduce the #ifdefs, which is unnecessary now that we can use IS_ENABLED() et al.
The image code is also where quite a bit of code is shared with the host tools. At present this uses a lot of checks of USE_HOSTCC.
This series introduces 'host' Kconfig options and a way to use CONFIG_IS_ENABLED() to check them. This works in a similar way to SPL, so
CONFIG_IS_ENABLED(FIT)
will evaluate to true on the host build (USE_HOSTCC) if CONFIG_HOST_FIT is enabled. This allows quite a bit of clean-up of the image.h header file and many of the image C files.
The 'host' Kconfig options should help to solve a more general problem in that we mostly want the host tools to build with all features enabled, no matter which features the 'target' build actually uses. This is a pain to arrange at present, but with 'host' Kconfigs, we can just define them all to y.
There are cases where the host tools do not have features which are present on the target, for example environment and physical addressing. To help with this, some of the core image code is split out into image-board.c and image-host.c files.
Even with these changes, some #ifdefs remain (101 down to 42 in common/image*). But the code is somewhat easier to follow and there are fewer build paths.
In service of the above, this series includes a patch to add an API function for zstd, so the code can be dropped from bootm.c
It also introduces a function to handle manual relocation.
Changes in v2: - Add a patch to introduce a memdup() function - Add new abuf_init_set() function - Update abuf_realloc() to return after every case - Use const for abuf_data() and abuf_size() - Make use of memdup() - Add abuf_init_move() - Add comments about the assumptions made by lib_test_abuf_realloc() - Add better comments about why some tests are skipped at present - Correct 'hose' typo - Fix up comment to put an underscore after every CONFIG - Correct comment about USE_HOSTCC being undefined in CONFIG_VAL() - Add SPL_ Kconfigs also, since otherwise hashing algorithms drop from SPL - Drop unnecessary setting of rd_len, etc. - Correct logic for the non-FIT case - Consider selecting a raw FDT to be success
