- Use "make _defconfig" instead of "make _config".
- Invoke tools/genboardscfg.py to generate boards.cfg when it is
missing.- Show "Building ${BOARD_NAME} board..." message.
(Prior to Kconfig, instead, mkconfig script displayed
"Configuring for ${BOARD_NAME} board..." but it was removed.)
Without this message, we cannot know which board is currently
being built.- Do not show "# configuration written to .config".
This message is useless and just annoying for MAKEALL.Signed-off-by: Masahiro Yamada

The old configuration script is no longer necessary.
Nor is boards.cfg a primary database.
We can generate it with the genboardscfg.py tool
based on the latest Kconfig, defconfig and MAINTAINERS.Signed-off-by: Masahiro Yamada

Now the primary data for each board is in Kconfig, defconfig and
MAINTAINERS.It is true boards.cfg is needed for MAKEALL and buildman and might be
useful to brouse all the supported boards in a single database.
But it would be painful to maintain the boards.cfg in sync.So, this is the solution.
Add a tool to generate the equivalent boards.cfg file based on
the latest Kconfig, defconfig and MAINTAINERS.We can keep all the functions of MAKEALL and buildman with it.
The best thing would be to change MAKEALL and buildman for not
depending on boards.cfg in the future, but it would take some time.Signed-off-by: Masahiro Yamada

We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.Signed-off-by: Masahiro Yamada

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.Signed-off-by: Masahiro Yamada

We are about to switch to Kconfig in the next commit.
But there are something to get done beforehand.In Kconfig, include/generated/autoconf.h defines boolean
CONFIG macros as 1.CONFIG_SPL and CONFIG_TPL, if defined, must be set to 1.
Otherwise, when switching to Kconfig, the build log
would be sprinkled with warning messages like this:

This commit adds more Kconfig files, which were written by hand.
Signed-off-by: Masahiro Yamada
Acked-by: Simon Glass -
This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board(This commit was automatically generated by a conversion script
based on boards.cfg)In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.Signed-off-by: Masahiro Yamada

U-Boot is expected to be built on various platforms.
We should keep in mind that the command 'make' is not always GNU Make,
while all the makefiles are written for GNU Make.For example, on Linux, people generally do:
make _config; make
But FreeBSD folks do
gmake _config; gmake
(The command 'make' on FreeBSD is BSD Make, not GNU Make)
It is not a good idea to hard-code the command name 'make'
in MAKEALL or buildman.They should call this helper script and get the command name
for GNU Make.Signed-off-by: Masahiro Yamada

Having a form of whitelist to check if we know of a CPU core
and and obtain CBAR is a bit silly.It doesn't scale (how about A12, A17, as well as other I don't know
about?), and is actually a property of the SoC, not the core.So either it works and everybody is happy, or it doesn't and
the u-boot port to this SoC is providing the real address via
a configuration option.The result of the above is that this code doesn't need to exist,
is thus forcefully removed.Signed-off-by: Marc Zyngier

The current non-sec switching code suffers from one major issue:
it cannot run in secure RAM, as a large part of u-boot still needs
to be run while we're switched to non-secure.This patch reworks the whole HYP/non-secure strategy by:
- making sure the secure code is the *last* thing u-boot executes
before entering the payload
- performing an exception return from secure mode directly into
the payload
- allowing the code to be dynamically relocated to secure RAM
before switching to non-secure.This involves quite a bit of horrible code, specially as u-boot
relocation is quite primitive.Signed-off-by: Marc Zyngier

If Series-to tag is missing, Patman exits with a message
"No recipient".This is just annoying for those who had already added
sendemail.to configuration.I guess many developers have
[sendemail]
to = u-boot@lists.denx.dein their .git/config because the 'To: u-boot@lists.denx.de' field
should always be added when sending patches.That seems more reasonable rather than adding
'Series-to: u-boot@lists.denx.de' to every patch series.Patman should exit only when both Series-to tag and sendemail.to
configuration are mising.Signed-off-by: Masahiro Yamada

At present buildman always builds out-of-tree, that is it uses a separate
output directory from the source directory. Normally this is what you want,
but it is important that in-tree builds work also. Some Makefile changes may
break this.Add a -i option to tell buildman to use in-tree builds, so that it is easy
to test this feature.Signed-off-by: Simon Glass

Normally buildman wil try to configure U-Boot for a particular board on the
first commit that it builds in a series. Subsequent commits are built
without reconfiguring which normally works. Where it doesn't, buildman
automatically reconfigures and retries.To fully emulate the way MAKEALL works, we should have an option to disable
this optimisation.Add a -C option to cause buildman to always reconfigure on each commit.
