      Subject: [PATCH 1/1] kbuild: Fix clang detection
      We cannot detect clang before including the arch Makefile, because that
      can set the default cross compiler. We also cannot detect clang after
      including the arch Makefile, because powerpc wants to know about clang.
      Solve this by using an deferred variable. This costs us a few shell
      invocations, but this is only a constant number.

      in the Linux kernel.
      This will allow us to make better decisions about when to run tests

      Move all command code into its own directory · 72a8cf8d
      Simon Glass authored
      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
      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
      +arch/m68k/cpu/mcf532x/start.o: In function `_start':

      I hope someone can shed some light on what this means. I hope it isn't
      depending on the position of code in the image.

      Various Makefiles: Add SPDX-License-Identifier tags · da58dec8
      Tom Rini authored
      After consulting with some of the SPDX team, the conclusion is that
      Makefiles are worth adding SPDX-License-Identifier tags too, and most of
      ours have one.  This adds tags to ones that lack them and converts a few
      that had full (or in one case, very partial) license blobs into the
      equivalent tag.

      Move board_init_f_mem() into a common location · af6bbd4d
      Simon Glass authored
      This function will be used by both SPL and U-Boot proper. So move it into
      a common place. Also change the #ifdef so that the early malloc() area is
      not set up in SPL if CONFIG_SYS_SPL_MALLOC_START is defined. In that case
      it would never actually be used, and just chews up stack space.

      x86: Generate a valid ACPI table · 867bcb63
      Saket Sinha authored

      Use a Kconfig option GENERATE_ACPI_TABLE to tell U-Boot whether we need
      actually write the APCI table just like we did for PIRQ routing, MP table
      and SFI tables. With ACPI table existence, linux kernel gets control of

      of: clean up OF_CONTROL ifdef conditionals · 0f925822
      Masahiro Yamada authored
      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
       # define OF_CONTROL 0
      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
      Also, we no longer have to cancel CONFIG_OF_CONTROL in
      include/config_uncmd_spl.h and scripts/Makefile.spl.

      As we discussed a couple of times, negative CONFIG options make our

      Now, there are three boards enabling OF_CONTROL on SPL:

       - socfpga_cyclone5_defconfig
       - socfpga_socrates_defconfig
      This commit adds CONFIG_SPL_OF_CONTROL for them and deletes

      dm: drop CONFIG_DM_DEVICE_REMOVE from uncmd list · 0a5804b5

      We do not want to compile the DM remove code for SPL.  Currently,

      linux/kconfig.h: add CPP macros useful for per-image config options · 8be60f06
      Masahiro Yamada authored
      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,
            (device tree code)
            (board file code)
      The ifdef conditional above is switched by CONFIG_OF_CONTROL during
      the U-Boot proper building (CONFIG_SPL_BUILD is not defined), and by
      The macro can be used in C context as well, so you can also write the
      equivalent code as follows:
            (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;
            text_base = CONFIG_TEXT_BASE;
      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.

      kbuild: add a makefile macro useful with per-image config options · 04a5c406
      Masahiro Yamada authored
      Commit e02ee254 ("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
        obj-$(CONFIG_FOO) += foo.o
      If CONFIG_SPL_FOO does not exist in Kconfig, it is equivalent to
        ifndef CONFIG_SPL_BUILD
        obj-$(CONFIG_SPL_FOO) += foo.o
      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:
                                            (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.

      arm: mvebu: Add Armada 38x DDR3 training code from Marvell bin_hdr · f1df9364
      Stefan Roese authored
      This patch adds the DDR3 setup and training code taken from the Marvell
      U-Boot repository. This code used to be included as a binary (bin_hdr)
      into the Armada A38x boot image. Not linked with the main U-Boot. With this
      code addition and the serdes/PHY setup code, the Armada A38x support
      in mainline U-Boot is finally self-contained. So the complete image
      for booting can be built from mainline U-Boot. Without any additional
      external inclusion.
      This code has undergone many hours (days!) of coding-style cleanup and
      refactoring. It still is not checkpatch clean though, I'm afraid. As the
      factoring of the code has so many levels of indentation that many lines
      are longer than 80 chars.

      arm: mvebu: drivers/ddr: Move Armada XP DDR init code into new directory · ff9112df
      Stefan Roese authored
      With the upcoming addition of the Armada 38x DDR support, which is not
      compatible to the Armada XP DDR init code, we need to introduce a new
      directory infrastructure. To support multiple Marvell DDR controller.
      This will be the new structure:
           Supporting Armada XP (AXP) devices (and perhaps Armada 370)
           Supporting Armada 38x devices (and perhaps Armada 39x)

      dm: Add a clock uclass · f26c8a8e
      Simon Glass authored
      Clocks are an important feature of platforms and have become increasing
      complex with time. Most modern SoCs have multiple PLLs and dozens of clock
      dividers which distribute clocks to on-chip peripherals.
      Some SoC implementations have a clock API which is private to that SoC family,
      e.g. Tegra and Exynos. This is useful but it would be better to have a
      common API that can be understood and used throughout U-Boot.
      Add a simple clock API as a starting point. It supports querying and setting
      the rate of a clock. Each clock is a device. To reduce memory and processing
      overhead the concept of peripheral clocks is provided. These do not need to
      be explicit devices - it is possible to write a driver that can adjust the
      I2C clock (for example) without an explicit I2C clock device. This can
      dramatically reduce the number of devices (and associated overhead) in a
      complex SoC.
      Clocks are referenced by a number, and it is expected that SoCs will define
      that numbering themselves via an enum.

      dm: Add support for RAM drivers · 6c51df68
      Simon Glass authored
      Add support for a driver which sets up DRAM and can return information about
      the amount of RAM available. This is a first step towards moving RAM init
      to driver model.
