Subject: [PATCH 1/1] kbuild: Fix clang detection
We cannot detect clang before including the arch Makefile, because that
can set the default cross compiler. We also cannot detect clang after
including the arch Makefile, because powerpc wants to know about clang.
Solve this by using an deferred variable. This costs us a few shell
invocations, but this is only a constant number.

There are a lot of unrelated files in common, including all of the commands.
Moving them into their own directory makes them easier to find and is more
logical.
Some commands include non-command code, such as cmd_scsi.c. This should be
sorted out at some point so that the function can be enabled with or without
the associated command.
Unfortunately, with m68k I get this error:
m68k: + M5329AFEE
+arch/m68k/cpu/mcf532x/start.o: In function `_start':

I hope someone can shed some light on what this means. I hope it isn't
depending on the position of code in the image.

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing

away the ugly logic in include/fdtdec.h:

# if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)

Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to
CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.
Also, we no longer have to cancel CONFIG_OF_CONTROL in
include/config_uncmd_spl.h and scripts/Makefile.spl.

The previous commit introduced a useful macro used in makefiles,
in order to reference to different variables (CONFIG_... or
CONFIG_SPL_...) depending on the build context.
Per-image config option control is a PITA in C sources, too.
Here are some macros useful in C/CPP expressions.
CONFIG_IS_ENABLED(FOO) can be used as a shorthand for
(!defined(CONFIG_SPL_BUILD) && defined(CONFIG_FOO)) || \
(defined(CONFIG_SPL_BUILD) && defined(CONFIG_SPL_FOO))
For example, it is useful to describe C code as follows,
#if CONFIG_IS_ENABLED(OF_CONTROL)
(device tree code)
#else
(board file code)
#endif
The ifdef conditional above is switched by CONFIG_OF_CONTROL during
the U-Boot proper building (CONFIG_SPL_BUILD is not defined), and by
CONFIG_SPL_OF_CONTROL during SPL building (CONFIG_SPL_BUILD is
defined).
The macro can be used in C context as well, so you can also write the
equivalent code as follows:
if (CONFIG_IS_ENABLED(OF_CONTROL)) {
(device tree code)
} else {
(board file code)
}
Another useful macro is CONFIG_VALUE().
CONFIG_VALUE(FOO) is expanded into CONFIG_FOO if CONFIG_SPL_BUILD is
undefined, and into CONFIG_SPL_FOO if CONFIG_SPL_BUILD is defined.
You can write as follows:
text_base = CONFIG_VALUE(TEXT_BASE);
instead of:
#ifdef CONFIG_SPL_BUILD
text_base = CONFIG_SPL_TEXT_BASE;
#else
text_base = CONFIG_TEXT_BASE;
#endif
This commit also adds slight hacking on fixdep so that it can
output a correct list of fixed dependencies.
If the fixdep finds CONFIG_IS_ENABLED(FOO) in a source file,
we want
$(wildcard include/config/foo.h)
in the U-boot proper building context, while we want
$(wildcard include/config/spl/foo.h)
in the SPL build context.

Commit e02ee2548a ("kconfig: switch to single .config
configuration") made the configuration itself pretty simple,
instead, we lost the way to systematically enable/disable config
options for each image independently.
Our current strategy is, put entries into Makefile.spl for options
we need separate enabling, or once enable the options globally in
Kconfig and then undef them in Makefile.uncmd_spl if we do not want
to compile the features for SPL at all. Things are getting really
messy. Besides, "ifdef CONFIG_SPL_BUILD" are sprinkled everywhere
in makefiles.
This commit adds a variable to help describe makefile simpler.
$(SPL_) evaluates to "SPL_" during the SPL build, while to an empty
string during building U-boot proper.
So, you can write
obj-$(CONFIG_$(SPL_)FOO) += foo.o
instead of
ifdef CONFIG_SPL_BUILD
obj-$(CONFIG_SPL_FOO) += foo.o
else
obj-$(CONFIG_FOO) += foo.o
endif
If CONFIG_SPL_FOO does not exist in Kconfig, it is equivalent to
ifndef CONFIG_SPL_BUILD
obj-$(CONFIG_SPL_FOO) += foo.o
endif
This is the pattern we often see in our current makefiles.
To take advantage of this macro, we should prefix SPL_ for the SPL
version of the option when we need independent control between
U-boot and SPL. With this naming scheme, I hope our makefiles will
be much simplified.
It means we want to rename existing config options as follows
in the long run:
CONFIG_SPL_SERIAL_SUPPORT -> CONFIG_SPL_SERIAL
CONFIG_SPL_I2C_SUPPORT -> CONFIG_SPL_I2C
CONFIG_SPL_GPIO_SUPPORT -> CONFIG_SPL_GPIO
CONFIG_SPL_SPI_SUPPORT -> CONFIG_SPL_SPI
CONFIG_SPL_DISABLE_OF_CONTROL -> CONFIG_SPL_OF_CONTROL
(inverting the logic)
Then drivers/Makefile would be re-worked as follows:
obj-$(CONFIG_$(SPL_)SERIAL) += serial/
obj-$(CONFIG_$(SPL_)I2C) += i2c/
obj-$(CONFIG_$(SPL_)GPIO) += gpio/
obj-$(CONFIG_$(SPL_)SPI) += spi/
...
Eventually, SPL-specialized entries in Makefile.spl would go away.

This patch adds the DDR3 setup and training code taken from the Marvell

into the Armada A38x boot image. Not linked with the main U-Boot. With this
code addition and the serdes/PHY setup code, the Armada A38x support
in mainline U-Boot is finally self-contained. So the complete image
for booting can be built from mainline U-Boot. Without any additional
external inclusion.
Note:
This code has undergone many hours (days!) of coding-style cleanup and
refactoring. It still is not checkpatch clean though, I'm afraid. As the
factoring of the code has so many levels of indentation that many lines
are longer than 80 chars.

Clocks are an important feature of platforms and have become increasing
complex with time. Most modern SoCs have multiple PLLs and dozens of clock
dividers which distribute clocks to on-chip peripherals.
Some SoC implementations have a clock API which is private to that SoC family,
e.g. Tegra and Exynos. This is useful but it would be better to have a
common API that can be understood and used throughout U-Boot.
Add a simple clock API as a starting point. It supports querying and setting
the rate of a clock. Each clock is a device. To reduce memory and processing
overhead the concept of peripheral clocks is provided. These do not need to
be explicit devices - it is possible to write a driver that can adjust the
I2C clock (for example) without an explicit I2C clock device. This can
dramatically reduce the number of devices (and associated overhead) in a
complex SoC.
Clocks are referenced by a number, and it is expected that SoCs will define

The SPL device tree size must be minimised to save memory. Only include
properties that are needed by SPL - this is determined by the presence
of the "u-boot,dm-pre-reloc" property. Also remove a predefined list of
unused properties from the nodes that remain.

I might have missed something, but I failed to use the escape char '\'
in strings. To pass a printf format string like "foo %d bar\n" via
Kconfig to the code.
Right now its not possible to use the escape character '\' in Kconfig
string values correctly to e.g. set this string value "test output\n".
The '\n' will be converted to 'n'.
The current implementation removes some of the '\' chars from the input
string in conf_set_sym_val(). Examples:
'\' -> ''
'\\' -> '\'
'\\\' -> '\'
'\\\\' -> '\\'
...
And then doubles the backslash chars in the output string in
sym_escape_string_value(). Example:
'\' -> '' -> ''
'\\' -> '\' -> '\\'
'\\\' -> '\' -> '\\'
'\\\\' -> '\\' -> '\\\\'
...
As you see in these examples, its impossible to generate a single '\'
charater in the output string as its needed for something like '\n'.
This patch now changes this behavior to not drop some backslashes in
conf_set_sym_val() and to not add new backslashes in the resulting
output string. Removing the function sym_escape_string_value()
completely as its not needed anymore.

When moving configs, it is important to know what was defined in the
config header even if it duplicates the configs coming from Kconfig.
This is specifically needed for the case where a config is set to
default 'y' in the Kconfig. This would previously cause the actual value
from the include config to be filtered out, and moveconfig.py would
think that it was 'n'... This means that the value that should be 'y'
is now (in every defconfig) set to 'not set'.
tools/moveconfig.py now defines KCONFIG_IGNORE_DUPLICATES to prevent the
filtering from happening and selecting wrong values for the defconfig.

This target was added by commit cbdd9a9737 (sunxi: kconfig: Add
%_felconfig rule to enable FEL build of sunxi platforms.).
At that time, U-Boot used separate .config files for U-Boot proper
and SPL. I understood the pain to modify both .config and
spl/.config.
Now, we have switched to single .config configuration.
It seems acceptable to run "make menuconfig" or friends to enable
CONFIG_SPL_FEL, as we do for other CONFIGs.

When Kconfig for U-boot was examined, one of the biggest issues was
how to support multiple images (Normal, SPL, TPL). There were
actually two options, "single .config" and "multiple .config".
After some discussions and thought experiments, I chose the latter,
i.e. to create ".config", "spl/.config", "tpl/.config" for Normal,
SPL, TPL, respectively.
It is true that the "multiple .config" strategy provided us the
maximum flexibility and helped to avoid duplicating CONFIGs among
Normal, SPL, TPL, but I have noticed some fatal problems:
[1] It is impossible to share CONFIG options across the images.
If you change the configuration of Main image, you often have to
adjust some SPL configurations correspondingly. Currently, we
cannot handle the dependencies between them. It means one of the
biggest advantages of Kconfig is lost.
[2] It is too painful to change both ".config" and "spl/.config".
Sunxi guys started to work around this problem by creating a new
configuration target. Commit cbdd9a9737 (sunxi: kconfig: Add
%_felconfig rule to enable FEL build of sunxi platforms.) added
"make *_felconfig" to enable CONFIG_SPL_FEL on both images.
Changing the configuration of multiple images in one command is a
generic demand. The current implementation cannot propose any
good solution about this.
[3] Kconfig files are getting ugly and difficult to understand.
Commit b724bd7d63 (dm: Kconfig: Move CONFIG_SYS_MALLOC_F_LEN to
Kconfig) has sprinkled "if !SPL_BUILD" over the Kconfig files.
[4] The build system got more complicated than it should be.
To adjust Linux-originated Kconfig to U-Boot, the helper script
"scripts/multiconfig.sh" was introduced. Writing a complicated
text processor is a shell script sometimes caused problems.
Now I believe the "single .config" will serve us better. With it,
all the problems above would go away. Instead, we will have to add
some CONFIG_SPL_* (and CONFIG_TPL_*) options such as CONFIG_SPL_DM,
but we will not have much. Anyway, this is what we do now in
scripts/Makefile.spl.
I admit my mistake with my apology and this commit switches to the
single .config configuration.
It is not so difficult to do that:
- Remove unnecessary processings from scripts/multiconfig.sh
This file will remain for a while to support the current defconfig
format. It will be removed after more cleanups are done.
- Adjust some makefiles and Kconfigs
- Add some entries to include/config_uncmd_spl.h and the new file
scripts/Makefile.uncmd_spl. Some CONFIG options that are not
supported on SPL must be disabled because one .config is shared
between SPL and U-Boot proper going forward. I know this is not
a beautiful solution and I think we can do better, but let's see
how much we will have to describe them.
- update doc/README.kconfig
More cleaning up patches will follow this.

In U-Boot, SoC-specific headers are placed in
arch/$(ARCH)/include/asm/arch-$(SOC) and a symbolic link to that
directory is created at the early stage of the build process.
Creating and removing a symbolic link during the build is not
preferred. In fact, Linux Kernel did away with include/asm-$(ARCH)
directories a long time time ago.
As for ARM, now it is possible to collect SoC sources into
arch/arm/mach-$(SOC). It is also reasonable to move SoC headers
into arch/arm/mach-$(SOC)/include/mach.
This commit prepares for that.
If the directory arch/$(ARCH)/mach-$(SOC)/include/mach exists,
a symbolic to that directory is created. Otherwise, a symbolic link
to arch/$(ARCH)/include/asm/arch-$(SOC) or arch-$(CPU) is created.
