u-boot.git/common/image.c, branch master

Create a new boot/ directory

2021-11-12T00:01:56+00:00

Quite a lot of the code in common/relates to booting and images. Before
adding more it seems like a good time to move the code into its own
directory.

Most files with 'boot' or 'image' in them are moved, except:

- autoboot.c which relates to U-Boot automatically running a script
- bootstage.c which relates to U-Boot timing

Drop the removal of boot* files from the output directory, since this
interfers with the symlinks created by tools and there does not appear
to be any such file from my brief testing.

lz4: Use a private header for U-Boot

2021-10-09T17:09:56+00:00

At present U-Boot has a header file called lz4.h for its own use. If the
host has its own lz4 header file installed (e.g. from the 'liblz4-dev'
package) then host builds will use that instead.

Move the U-Boot file into its own directory, as is done with various
other headers with the same problem.

image: Drop IMAGE_ENABLE_OF_LIBFDT

2021-10-08T19:53:26+00:00

Add a host Kconfig for OF_LIBFDT. With this we can use
CONFIG_IS_ENABLED(OF_LIBFDT) directly in the tools build, so drop the
unnecessary indirection.

Make use of the host Kconfig for FIT. With this we can use
CONFIG_IS_ENABLED(FIT) directly in the host build, so drop the unnecessary
indirection.

compiler: Rename host_build() to tools_build()

2021-10-08T19:53:26+00:00

With the new TOOLS_LIBCRYPTO and some other changes, it seems that we are
heading towards calling this a tools build rather than a host build,
although of course it does happen on the host.

I cannot think of anything built by the host which cannot be described as
a tool, so rename this function.

image: Create a function to do manual relocation

2021-10-08T19:53:26+00:00

Rather than adding an #ifdef and open-coding this calculation, add a
helper function to handle it. Use this in the image code.

image: Split host code out into its own file

2021-10-08T19:53:26+00:00

To avoid having #ifdefs in a few functions which are completely different
in the board and host code, create a new image-host.c file.

image: Split board code out into its own file

2021-10-08T19:53:26+00:00

To avoid a large #ifdef in the image.c file, move the affected code into
a separate file.

Avoid any style fix-ups for easier review. Those are in the next patch.

image: Update image_decomp() to avoid ifdefs

2021-10-08T19:53:26+00:00

Adjust this function so that preprocessor macros are not needed. With
this, the host build uses more of the same header files as the target
build.

Rather than definining CONFIG_SYS_MALLOC_LEN, add a CONSERVE_MEMORY
define, since that is the purpose of the value.

This appears to have no impact on code size from a spot check of a few
boards (snow, firefly-rk3288, boston32r2el, m53menlo).

image: Update zstd to avoid reporting error twice

2021-10-08T19:53:26+00:00

The zstd implementation prints the error in image_decomp() which is
incorrect and does not match other algorithms. Drop this and let the
caller report the error.
