u-boot.git/Kconfig, branch v2022.01

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.

kconfig / kbuild: Re-sync with Linux 4.20

2021-07-14T20:57:35+00:00

Align Kconfig and Kbuild logic to Linux 4.20 release with minimal impact
on files outside of this scope.

Our previous Kconfig sync was done by commit 587e4a429698 ("kconfig /
kbuild: Re-sync with Linux 4.19").

As part of this re-sync, a few related changes from previous Linux
releases were found to have been missed and merged in, and are not in
the following list.

The imported Linux commits are:

[From prior to v4.19]
b1e0d8b70fa3 kbuild: Fix gcc -x syntax
a4353898980c kconfig: add CC_IS_GCC and GCC_VERSION

There are a number of changes related to additional warnings as well as
being able to drop cc-name entirely that have been omitted for now as
additional work is required first.

build: support building with Link Time Optimizations

2021-05-24T18:21:30+00:00

Add plumbing for building U-Boot with Link Time Optimizations.

When building with LTO, $(PLATFORM_LIBS) has to be in --whole-archive /
--no-whole-archive group, otherwise some functions declared in assembly
may not be resolved and linking may fail.

Note: clang may throw away linker list symbols it thinks are unused when
compiling with LTO. To force these symbols to be included, we refer to
them via the __ADDRESSABLE macro in a C file generated from compiled
built-in.o files before linking.

spl: Tidy up SPL/TPL malloc sizes

2021-01-30T21:25:41+00:00

The current help talks about relocation which doesn't apply to SPL and
TPL. Update it to avoid confusion.

Also make the TPL size default to the same as the SPL size, since this is
more likely to be a useful value than the one used by U-Boot proper, which
may be quite a bit larger.

arm: actions: increase SYS_MALLOC_F_LEN

2020-11-09T19:18:10+00:00

after commit 4ab3817ff16a ("clk: fixed-rate: Enable DM_FLAG_PRE_RELOC flag")
Cubieboard7 (based on actions S700 SoC) fails to boot.

It is due to the fact that the default value of CONFIG_SYS_MALLOC_F_LEN (0x400)
would not provide enough memory for clock device to probe (before relocation)
well.

This commit fixes it, by increasing SYS_MALLOC_F_LEN to value 0x2000.

Kconfig: Increase the pre-relocation memory

2020-10-28T15:49:31+00:00

The memory is close to full and adding a syscon node in test.dts makes
it go over the limit and makes malloc() fail on startup.
