[U-Boot] [PATCH 00/16] Add macros to ease our life with independent CONFIGs between U-Boot and SPL

[U-Boot] [PATCH 00/16] 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.



Masahiro Yamada (16):

[U-Boot] [PATCH 01/16] ARM: remove vpac270 board support

[Masahiro Yamada]

The board-specific linker script board/vpac270/u-boot-spl.lds
obstructs further cleanup.  This board has not been converted to
Generic Board yet in spite of the long-term warning.  Remove.

Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

Marek,

If you want to keep this board:
  - Please convert it to Generic Board
  - Please use arch-common linker script

Hi!

Yeah, I want to keep this board, but please give me a bit of time
to do this. This one and the zipitz2 are the two PXA boards which
I have and want to keep.

I recall the u-boot-spl.lds was really needed to keep the size of
the SPL under 1kiB ; without this the board was unbootable when
using the OneNAND.

Best regards,

So, you worked around your problem in a wrong way.

I imagine this linker script means:
We build many objects for SPL, but do not want link them.
To keep the SPL size under 1kiB, only 4 objects should be
linked into the SPL.
The correct way of doing this is to disable CONFIGs for SPL,
by Kconfig or by include/configs/vpac270.h, but it is troubulesome
(or tedious, or impossible at all?), so this weird linker script is needed...

I'd say having per-board linker scripts is a mistake of U-boot.
They should be deprecated in the long-run.


Is it possible to replace

 drivers/mtd/onenand/built-in.o

with

 drivers/built-in.o

Given that any other drivers should be disabled for SPL,
this should work.

And it should be enough for my series.

I will drop this patch when I send v2.


BTW, I tried building vpac270 ONENAND.
It is already over 1kiB.

So the hardware spilt already? Aww :-(

I wonder, maybe converting this to TPL might be the correct solution ?

I think I might need TPL and SPL:

TPL: Load the SDRAM init code into CPU's SRAM from the OneNAND
SPL: Load big U-Boot from OneNAND into the main SDRAM

... or maybe we should just sacrifice the machine in the name of progress
and be done with it. I don't know when I might have time to fix it afterall.

Well it sounds like it is already broken. It worries me that SPL has
somehow got larger though - any reason for that?

I think the machine was always quite borderline and stuffing the SPL into
it was always a bit hackish. The changes to the SPL probably just exposed
this hackishness.

[U-Boot] [PATCH 03/16] 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 04/16] 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 13/16] 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 15/16] 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 16/16] 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.

CONFIG_IS_ENABLED() is a bit too verbose. Could we get something
shorter, like ENABLED()?

Linux has an IS_ENABLED() macro to my knowledge.

The prefix "CONFIG_" is important because this must be
searched by scripts/basic/fixdep.c


We are familiar with IS_ENABLED() which originates in Linux,
so a new build-context-depending macro, CONFIG_IS_ENABLED() is
reasonable naming, I believe.

Besides,

IS_ENABLED(CONFIG_OF_CONTROL)  - before
CONFIG_IS_ENABLED(OF_CONTROL)  - after


Same length.  Not too verbose.

What about CONFIG_EN(OF_CONTROL), then? I don't think confusion is
possible...

I don't like CONFIG_EN(), sorry. It looks like shortening something just
for the sake of shortening it, which is only confusing.

We had something systematic -- separate .configs, which could have been used 
to get rid of the CONFIG_SPL_FRED_SUPPORT stuff -- that you reverted (which 
was the only reason the uncmd stuff ever existed).

Yet somehow this is "much better". :-(

With separate .config this is just:

#ifdef CONFIG_FOO
        ...
#endif
