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

This is how CONFIG options are defined by Kconfig.
Signed-off-by: Masahiro Yamada
Acked-by: Michal Simek -
For historical reason, CONFIG_SYS_TEXT_BASE has been specified
in various ways:[1] by board/${VENDOR}/${BOARD}/config.mk
[2] by CONFIG_SYS_EXTRA_OPTIONS
(This was "options" field of boards.cfg before Kconfig conversion)[3] by include/configs/${BOARD}.h
[4] by configs/${BOARD}_defconfig
Most of M68K boards use either [1] or [2], both of which we want to
deprecate. Switch them into [4], which is the newest way (Kconfig).We still allow [3] too, because it is still used by many boards and
we expect much time for conversion.Signed-off-by: Masahiro Yamada

At present in SPL we place the device tree immediately after BSS. This
avoids needing to copy it out of the way before BSS can be used. However on
some boards BSS is not placed with the image - e.g. it can be in RAM if
available.Add an option to tell U-Boot that the device tree should be placed at the
end of the image binary (_image_binary_end) instead of at the end of BSS.Note: A common reason to place BSS in RAM is to support the FAT filesystem.
We should update the code so that it does not use so much BSS.Signed-off-by: Simon Glass

malloc_simple uses a part of the stack as heap, initially it uses
SYS_MALLOC_F_LEN bytes which typically is quite small as the initial
stacks sits in SRAM and we do not have that much SRAM to work with.When DRAM becomes available we may switch the stack from SRAM to DRAM
to give use more room. This commit adds support for also switching to
a new bigger malloc_simple heap located in the new stack.Note that this requires spl_init to be called before spl_relocate_stack_gd
which in practice means that spl_init must be called from board_init_f.Signed-off-by: Hans de Goede

common/dlmalloc.c is quite big, both in .text and .data usage, therefor
on some boards the SPL is build to use only malloc_simple.c and not the
dlmalloc.c code. This is done in various include/configs/foo.h with the
following construct:#ifdef CONFIG_SPL_BUILD
#define CONFIG_SYS_MALLOC_SIMPLE
#endifThis commit introduces a SPL_MALLOC_SIMPLE Kconfig bool which allows
selecting this functionality through Kconfig instead.Signed-off-by: Hans de Goede

This option has a bool type, not hex.
Fix it and enable it if CONFIG_DM is on because Driver Model always
requires malloc memory. Devices are scanned twice, before/after
relocation. CONFIG_SYS_MALLOC_F should be enabled to use malloc
memory before relocation. As it is board-independent, handle it
globally.Signed-off-by: Masahiro Yamada

This commit introduces new config: CONFIG_SYS_MALLOC_CLEAR_ON_INIT.
This config is an expert option and is enabled by default.
The all amount of memory reserved for the malloc, is by default set
to zero in mem_malloc_init(). When the malloc reserved memory exceeds
few MiB, then the boot process can slow down.So disabling this config, is an expert option to reduce the boot time,
and can be disabled by Kconfig.Note:
After disable this option, only calloc() will return the pointer
to the zeroed memory area. Previously, without this option,
the memory pointed to untouched malloc memory region, was filled
with zeros. So it means, that code with malloc() calls should
be reexamined.Signed-off-by: Przemyslaw Marczak

At present SPL uses a single stack, either CONFIG_SPL_STACK or
CONFIG_SYS_INIT_SP_ADDR. Since some SPL features (such as MMC and
environment) require a lot of stack, some boards set CONFIG_SPL_STACK to
point into SDRAM. They then set up SDRAM very early, before board_init_f(),
so that the larger stack can be used.This is an abuse of lowlevel_init(). That function should only be used for
essential start-up code which cannot be delayed. An example of a valid use is
when only part of the SPL code is visible/executable, and the SoC must be set
up so that board_init_f() can be reached. It should not be used for SDRAM
init, console init, etc.Add a CONFIG_SPL_STACK_R option, which allows the stack to be moved to a new
address before board_init_r() is called in SPL.The expected SPL flow (for CONFIG_SPL_FRAMEWORK) is documented in the README.

Now CONFIG_SPL_BUILD is not defined in Kconfig, so
"!depends on SPL_BUILD" and "if !SPL_BUILD" are redundant.Signed-off-by: Masahiro Yamada

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 cbdd9a9737cc (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 b724bd7d6349 (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.

At present defaults in arch-specific Kconfig files are ignored if the
top-level item comes ahead of it in include order. This means that it is
not possible to have a U-Boot default that architectures and boards can
override. This does not seem very useful.Move the include earlier to support this.

It makes sense to specify CONFIG_SYS_CLK_FREQ in "configs/xx_defconfig"
instead of "include/configs/xxx.h" because then header will be reusable

himself via "menuconfig".For now I'm only applying this change to all ARC configs because
otherwise scope of change will be huge.Signed-off-by: Alexey Brodkin
