kbuild: Bump the build system to 6.1

2026-01-02T16:28:14+00:00

Our last sync with the kernel was 5.1.

We are so out of sync now, that tracking the patches and backporting
them one by one makes little sense and it's going to take ages.

This is an attempt to sync up Makefiles to 6.1.
Unfortunately due to sheer amount of patches this is not easy to review,
but that's what we decided during a community call for the bump to 5.1,
so we are following the same guidelines here.

include/version.h: workaround sysroot inc order

2018-09-11T00:20:34+00:00

On some systems the host system or even the cross sysroot can
contain a version.h.  This leads to the wrong file being picked
up and a PLAIN_VERSION undefined error.

This workaround symlinks the version.h into the tool folder to
allow reordering of search folders.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

env: Remove CONFIG_ENV_AES support

2017-11-21T12:43:31+00:00

This support has been deprecated since v2017.09 due to security issues.
We now remove this support.

tools: fix cross-compiling tools when HOSTCC is overridden

2017-03-15T00:40:22+00:00

Richard reported U-Boot tools issues in OpenEmbedded/Yocto project.

OE needs to be able to change the default compiler. If we pass in
HOSTCC through the make command, it overwrites all HOSTCC instances,
including ones in tools/Makefile and tools/env/Makefile, which breaks
"make cross_tools" and "make env", respectively.

Add "override" directives to avoid overriding HOSTCC instances that
really need to point to the cross-compiler.

Allow fw env tools to be available as library

2015-11-18T13:47:03+00:00

Sometimes it can be useful to link the fw_ tools instead
of having the fw_setenv/fw_printenv installed.
Patch exports the tool as library and allowes to link it
with own programs.

tools/env: change stripping strategy to allow no-stripping

2014-09-24T22:30:27+00:00

When building the U-Boot tools for non-ELF platforms (such as Blackfin
FLAT), since commit 79fc0c5f498c3982aa4740c273ab1a9255063d9c
("tools/env: cross-compile fw_printenv without setting HOSTCC"), the
build fails because it tries to strip a FLAT binary, which does not
make sense.

This commit solves this by changing the stripping logic in
tools/env/Makefile to be similar to the one in tools/Makefile. This
logic continues to apply strip to the final binary, but does not abort
the build if it fails, and does the stripping in place on the final
binary. This allows the logic to work fine if stripping doesn't work,
as it leaves the final binary untouched.

kconfig: switch to Kconfig

2014-07-30T12:48:03+00:00

This commit enables Kconfig.
Going forward, we use Kconfig for the board configuration.
mkconfig will never be used. Nor will include/config.mk be generated.

Kconfig must be adjusted for U-Boot because our situation is
a little more complicated than Linux Kernel.
We have to generate multiple boot images (Normal, SPL, TPL)
from one source tree.
Each image needs its own configuration input.

Usage:

Run "make _defconfig" to do the board configuration.

It will create the .config file and additionally spl/.config, tpl/.config
if SPL, TPL is enabled, respectively.

You can use "make config", "make menuconfig" etc. to create
a new .config or modify the existing one.

Use "make spl/config", "make spl/menuconfig" etc. for spl/.config
and do likewise for tpl/.config file.

The generic syntax of configuration targets for SPL, TPL is:

  /

Here,  is either 'spl' or 'tpl'
       is 'config', 'menuconfig', 'xconfig', etc.

When the configuration is done, run "make".
(Or "make _defconfig all" will do the configuration and build
in one time.)

For futher information of how Kconfig works in U-Boot,
please read the comment block of scripts/multiconfig.py.

By the way, there is another item worth remarking here:
coexistence of Kconfig and board herder files.

Prior to Kconfig, we used C headers to define a set of configs.

We expect a very long term to migrate from C headers to Kconfig.
Two different infractructure must coexist in the interim.

In our former configuration scheme, include/autoconf.mk was generated
for use in makefiles.
It is still generated under include/, spl/include/, tpl/include/ directory
for the Normal, SPL, TPL image, respectively.

env: Implement support for AES encryption into fw_* tools

2014-03-21T20:44:08+00:00

Implement support for encrypting/decrypting the environment block
into the tools/env/fw_* tools. The cipher used is AES 128 CBC and
the implementation depends solely on components internal to U-Boot.

To allow building against the internal AES library, the library did
need minor adjustments to not include U-Boot's headers which are not
wanted to be included and define missing types.

kbuild: rename SRCTREE to srctree

2014-03-12T21:04:57+00:00

Prior to Kbuild, $(TOPDIR) or $(SRCTREE) was used for
pointing to the top of source directory.
(No difference between the two.)

In Kbuild style, $(srctree) is used for instead.
This commit renames SRCTREE to srctree and deletes the
defition of SRCTREE.

Note that SRCTREE in scripts/kernel-doc, scripts/docproc.c,
doc/DocBook/Makefile should be keep.
