SPL should not use DM_SPI_FLASH, this is already cleaned in

Since we don't support DM in SPL, undefine the DM USB in SPL build,
so it can use non-DM USB driver.Signed-off-by: Ye Li

This syncs up the current cmd/Kconfig and include/configs/ files with the
only exception being CMD_NAND. Due to how we have used this historically
we need to take further care here when converting.Signed-off-by: Tom Rini

The Device Model sequence alias feature is required by some Uclasses.
Instead of disabling the feature for all SPL targets allow it to be
configured.The config option is disabled by default to reduce code size for targets
that are not interested or do not require this feature.Signed-off-by: Nathan Rossi

We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing
devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:#ifdef CONFIG_OF_CONTROL
# if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL)
# define OF_CONTROL 0
# else
# define OF_CONTROL 1
# endif
#else
# define OF_CONTROL 0
#endifNow 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.Signed-off-by: Masahiro Yamada

As we discussed a couple of times, negative CONFIG options make our
life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ...
and here is another one.Now, there are three boards enabling OF_CONTROL on SPL:
- socfpga_arria5_defconfig
- socfpga_cyclone5_defconfig
- socfpga_socrates_defconfigThis commit adds CONFIG_SPL_OF_CONTROL for them and deletes
CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert
the logic.Signed-off-by: Masahiro Yamada

We do not want to compile the DM remove code for SPL. Currently,
we undef it in include/config_uncmd_spl.h (for C files) and in
scripts/Makefile.uncmd_spl (for Makefiles). This is really ugly.This commit demonstrates how we can deprecate those two files.
Use $(SPL_) for the entry in the Makfile and CONFIG_IS_ENABLED()
in C files.Signed-off-by: Masahiro Yamada

Allow SPL to be built with this option so that we can support device tree
control. Disable the simple bus for now in SPL. It may be needed later.Signed-off-by: Simon Glass

In many cases SPL only uses a single serial port and there is no need for
alias sequence support. We will just use the serial port pointed to by
stdout-path in the /chosen node.Signed-off-by: Simon Glass

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.

This patch adds support for networking in SPL. Some devices are
capable of loading SPL via network so it makes sense to load the
main U-Boot binary via network too. This patch tries to use
existing network code as much as possible. Unfortunately, it depends
on environment which in turn depends on other code so SPL size
is increased significantly. No effort was done to decouple network
code and environment so far.Signed-off-by: Ilya Yanok
