[U-Boot] [PATCH v2 00/15] Add macros to ease our life with independent CONFIGs between U-Boot and SPL

[Masahiro Yamada]

Refer to Simon's question, too:
http://lists.denx.de/pipermail/u-boot/2015-July/219598.html

Since U-boot introduced SPL (not since Kconfig),
enabling features for U-boot and SPL independently is always a PITA.

 - decide if each feature should be supported for SPL or not
 - Add CONFIG_SPL_FRED_SUPPORT into Makefile.spl
 - Add #undef include/config_uncmd_spl.h to disable features
   we do not want to support on SPL
 - Add "ifdef CONFIG_SPL_BUILD ... endif" here and there to adjust things
 - Add "#ifdef CONFIG_SPL_BUILD ... #endif" here and there to fix things up

Things are getting more and more crappy.

When U-boot switched to Kconfig, first I introduced separate .config
(.config, spl/.config, tpl/.config) to clean up them.
But it turned out to be a pain.

So, I believe the current single .config is much better.
But I also admit we need something systematic to subdue our PITA.

One possibility is to support "spl-y" in makefiles.
(This idea is cribbed from barebox.)

  obj-$(CONFIG_FOO) += foo.o
  spl-$(CONFIG_SPL_FOO) += foo.o

is cleaner than

  ifdef CONFIG_SPL_BUILD
    obj-$(CONFIG_SPL_FOO) += foo.o
  else
    obj-$(CONFIG_FOO) += foo.o
  endif

It is a nice improvement in makefile side.
But we still need to do something with C files.

Another option is something like
   CONFIG_FOO=yyn  (yes for U-boot, yes for SPL, no for TPL)

To achieve this, I think a big operation is needed in Kconfig core.
I cannot do that.
(Of course, Patches are welcome if someone else can do that.)

So, I was thinking of something different.

My idea was inspired by IS_ENABLED() macro in include/linux/kconfig.h.

Linux defines different macros for built-in and module,
and it is possible to write
   #if IS_ENABLED(CONFIG_FOO)
           ...
   #endif

 instead of

   #if defined(CONFIG_FOO) || defined(CONFIG_FOO_MODULE)
           ...
   #endif

So, I'd like to propose new macros to write code like

   #if CONFIG_IS_ENABLED(FOO)
            ...
   #endif

 instead of

   #if (!defined(CONFIG_SPL_BUILD) && defined(CONFIG_FOO)) || \
         (defined(CONFIG_SPL_BUILD) && defined(CONFIG_SPL_FOO))
             ...
   #endif

I hope this series will make our life easier.

[U-Boot] [PATCH v2 01/15] kbuild: fixdep: optimize code slightly

[Masahiro Yamada]

If the target string matches "CONFIG_", move the pointer p
forward.  This saves several 7-chars adjustments.

[U-Boot] [PATCH v2 02/15] kbuild: add a makefile macro useful with per-image config options

[Masahiro Yamada]

Commit e02ee2548afe ("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.

[U-Boot] [PATCH v2 03/15] linux/kconfig.h: add CPP macros useful for per-image config options

[Masahiro Yamada]

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.

[U-Boot] [PATCH v2 04/15] spl: move SPL driver entries to driver/Makefile

[Masahiro Yamada]

Just preparing for upcoming cleaning.

The board-specific linker script  board/vpac270/u-boot-spl.lds
has been touched to avoid build error.  It does not change the
size of spl/u-boot-spl.bin for this board, so it should be OK.

Changes in v2:
  - Do not delete vpac270 board.
    Instead, change board/vpac270/u-boot-spl.lds

[U-Boot] [PATCH v2 12/15] dm: drop CONFIG_DM_DEVICE_REMOVE from uncmd list

[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.

[U-Boot] [PATCH v2 14/15] of: flip CONFIG_SPL_DISABLE_OF_CONTROL into CONFIG_SPL_OF_CONTROL

[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 actually two boards enabling OF_CONTROL on SPL:
 - socfpga_arria5_defconfig
 - socfpga_cyclone5_defconfig

But they were enabled by mistake.

Commit 47a785a9dd97 ("dts: Disable device tree for SPL on all
boards") missed to add CONFIG_SPL_DISABLE_OF_CONTROL on those
two boards.  They were silently enabled with OF_CONTROL on SPL
without notifying their maintainers.

After all, there exist no boards to support it in a justified
process.

Before being too late, delete all the defines in defconfig files
and 'select's in Kconfig, and invert the logic.

[U-Boot] [PATCH v2 15/15] of: clean up OF_CONTROL ifdef conditionals

[Masahiro Yamada]

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
 #endif

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.

[U-Boot] [PATCH v2 02/15] kbuild: add a makefile macro useful with per-image config options

I agree. This seems like a clever solution to the problem.

As you probably saw on the other thread, Scott Wood suggested that
separate configs for U-Boot proper and SPL are better. There are
definitely arguments either way.

I feel that joining them up has a few advantages:
- Single configuration step (no multiple 'make menuconfig' steps)
- Supports the common case where there is no need for a separate SPL option
- Single configuration file to maintain / patch
- Avoids needing to create options that depend on SPL, or !SPL and
thus exist in SPL but not in U-Boot proper (I find this confusing)

The $(SPL) syntax may be a little clumsy but it is pretty clear what
is going on. Also if we come up with something else in the future it
should be fairly easy to revisit the sits and change them.

I believe the common case is that most board options are the same for
SPL and U-Boot proper. By my count we have about 40
CONFIG_SPL_..._SUPPORT optoins at present. Compared to the thousands
of options int the source this is fairly small. So we should optimise
for the common case.

There are definitely trade-offs and I'm sure people will continue to
think about it.

But most important I think this solves the problem on the thread
Masahiro references.

Simon

Yes it looks like they converted in between me generating the patch
and applying it. I did not notice. This underlines that we should
avoid negative options.

In any case this option only exists to avoid breaking existing boards
and I was hoping to drop it. My only concern here is that the option
(for a baord to use device tree in U-Boot proper but not in SPL) will
now live on. Still, for a few boards this will be necessary.

How often do people use menuconfig versus a board's defconfig?  Even when 
they do, do they need to modify the SPL's config or just the main U-Boot?

> - Supports the common case where there is no need for a separate SPL option

With separate configs there would not be separate options.  With a unified 
config there are separate SPL options, even if it doesn't require a separate 
makefile line.

> - Single configuration file to maintain / patch

For defconfigs it was already merged.

Instead you have special SPL symbols that exist but don't mean anything in U-
Boot proper...

Most SPLs have a command shell and all the associated bells and whistles 
selected, plus a full set of drivers?

Those were added before we had split configs.  With split configs they could 
go away.

40 versus zero?  What special thing would need to be done to the "thousands 
of options" with split configs?

How is TPL supposed to be handled?  Are the various SPL options that are set 
one way #ifdef CONFIG_TPL_BUILD and differently if not doomed to stay in the 
board config file and never get kconfigized?

It often happened when I changed SoC-specific features.

Yes, with mysterious "+S:" prefixes.
Internally, it was divided into separate defconfigs by a shell script
before going into Kconfig.

True, but on the contrary, CONFIG options without CONFIG_SPL_ is meaningful
for SPL.

For example,

common/spl/spl_nand.c is only linked into SPL,
but it references CONFIG_SYS_TEXT_BASE.


SPL needs CONFIG_SPL_TEXT_BASE to link itself,
and also wants to know CONFIG_SYS_TEXT_BASE
for loading the U-boot proper image.


The single .config is sometimes helpful for inter-action between U-boot proper
and SPL.

Simon did not go as far as saying that.

The command shell should be available on U-Boot proper, I think.

But, yeah, Freescale finally enabled the command shell on SPL.

At some point, the order of SPL and TPL should be swapped.

TPL (Tiny Program Loader)  ->  SPL  ->  U-Boot

Then, TPL will become an ad-hoc loader, disabling most of CONFIGs.
Implementation is Do-It-Yourself things under you board directory or somewhere.
