devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear
away the ugly logic in include/fdtdec.h:

CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for
SPL.

linux/kconfig.h: add CPP macros useful for per-image config options

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.

9 years agokbuild: add a makefile macro useful with per-image config options
Masahiro Yamada [Tue, 11 Aug 2015 22:31:42 +0000 (07:31 +0900)]
kbuild: add a makefile macro useful with per-image config options

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.

A board which requires the SPI NOR to be accessed in larger 32KiB
or 64KiB pages can disable the 4K subpage support, but by default,
the support for 4K subpage I/O is enabled. The functionality of this
option is the same as CONFIG_MTD_SPI_NOR_USE_4K_SECTORS in Linux.

This is extremely useful in case one uses UBI on a SPI NOR flash.
UBI needs at least 15k EBs and can not work on a flash which uses
4k ones, so disabling the support for 4k subpages lets UBI work on
such flash.
