      Revert "Ensure device tree DTS is compiled" · a3444bd0
      Masahiro Yamada authored
      This reverts commit 27cb7300.
      
      I am not sure if I correctly understood the log of commit 27cb7300
      ("Ensure device tree DTS is compiled"), but the code-diff looks like
      it was trying to solve the missed re-compilation when .dts was modified.
      
      Recently, commit 2737dfe0 ("kbuild: make arch-dtbs target PHONY")
      fixed the issue in a more correct and more complete way.
      
      Anyway, since the former commit, we see a clumsy log like this:
      
        make[2]: 'arch/sandbox/dts/sandbox.dtb' is up to date
      
      Another problem is, it created multiple paths to descend into
      arch/*/dts/, causing a race in parallel building.
      
      So, let's revert it.

      kbuild: add .SECONDARY special target to scripts/Kbuild.include · c16b137e
      Masahiro Yamada authored
      Based on the following Linux commits:
      
       - 54a702f70589 ("kbuild: mark $(targets) as .SECONDARY and remove
         .PRECIOUS markers")
      
       - 8e9b61b293d9 ("kbuild: move .SECONDARY special target to
         Kbuild.include")
      
      GNU Make automatically deletes intermediate files that are updated
      in a chain of pattern rules.
      
      Example 1) %.dtb.o <- %.dtb.S <- %.dtb <- %.dts
      Example 2) %.o <- %.c <- %.c_shipped
      
      A couple of makefiles mark such targets as .PRECIOUS to prevent Make
      from deleting them, but the correct way is to use .SECONDARY.
      
        .SECONDARY
          Prerequisites of this special target are treated as intermediate
          files but are never automatically deleted.
      
        .PRECIOUS
          When make is interrupted during execution, it may delete the target
          file it is updating if the file was modified since make started.
          If you mark the file as precious, make will never delete the file
          if interrupted.
      
      Both can avoid deletion of intermediate files, but the difference is
      the behavior when Make is interrupted; .SECONDARY deletes the target,
      but .PRECIOUS does not.
      
      The use of .PRECIOUS is relatively rare since we do not want to keep
      partially constructed (possibly corrupted) targets.
      
      .SECONDARY with no prerequisites causes all targets to be treated as
      secondary. This agrees the policy of Kbuild.
      
      scripts/Kbuild.include seems a suitable place to add it because it is
      included from almost all sub-makes.

      board: arm: Add support for Broadcom BCM7445 · 894c3ad2
      Thomas Fitzsimmons authored
      Add support for loading U-Boot on the Broadcom 7445 SoC.  This port
      assumes Broadcom's BOLT bootloader is acting as the second stage
      bootloader, and U-Boot is acting as the third stage bootloader, loaded
      as an ELF program by BOLT.

      SPDX: Convert all of our single license tags to Linux Kernel style · 83d290c5
      Tom Rini authored
      When U-Boot started using SPDX tags we were among the early adopters and
      there weren't a lot of other examples to borrow from.  So we picked the
      area of the file that usually had a full license text and replaced it
      with an appropriate SPDX-License-Identifier: entry.  Since then, the
      Linux Kernel has adopted SPDX tags and they place it as the very first
      line in a file (except where shebangs are used, then it's second line)
      and with slightly different comment styles than us.
      
      In part due to community overlap, in part due to better tag visibility
      and in part for other minor reasons, switch over to that style.
      
      This commit changes all instances where we have a single declared
      license in the tag as both the before and after are identical in tag
      contents.  There's also a few places where I found we did not have a tag
      and have introduced one.

      pylibfdt: compile pylibfdt only when dtoc/binman is necessary · d6a0c78a
      Masahiro Yamada authored
      Currently, pylibfdt is always compiled if swig is installed on your
      machine.  It is really annoying because most of targets (excepts
      x86, sunxi, rockchip) do not use dtoc or binman.
      
      "checkbinman" and "checkdtoc" are wrong.  It is odd that the final
      build stage checks if we have built necessary tools.  If your platform
      depends on dtoc/binman, you must be able to build pylibfdt.  If swig
      is not installed, it should fail immediately.
      
      I added PYLIBFDT, DTOC, BINMAN entries to Kconfig.  They should be
      property select:ed by platforms that need them.  Kbuild will descend
      into scripts/dtc/pylibfdt/ only when CONFIG_PYLIBFDT is enabled.

      Allow boards to initialize the DT at runtime. · 82f766d1
      Alex Deymo authored
      In some boards like the Raspberry Pi the initial bootloader will pass
      a DT to the kernel. When using U-Boot as such kernel, the board code in
      U-Boot should be able to provide U-Boot with this, already assembled
      device tree blob.
      
      This patch introduces a new config option CONFIG_OF_BOARD to use instead
      of CONFIG_OF_EMBED or CONFIG_OF_SEPARATE which will initialize the DT
      from a board-specific funtion instead of bundling one with U-Boot or as
      a separated file. This allows boards like the Raspberry Pi to reuse the
      device tree passed from the bootcode.bin and start.elf firmware
      files, including the run-time selected device tree overlays.

      dm: Add callback to modify the device tree · 0db4cd25
      mario.six@gdsys.cc authored
      Certain boards come in different variations by way of utilizing daughter
      boards, for example. These boards might contain additional chips, which
      are added to the main board's busses, e.g. I2C.
      
      The device tree support for such boards would either, quite naturally,
      employ the overlay mechanism to add such chips to the tree, or would use
      one large default device tree, and delete the devices that are actually
      not present.
      
      Regardless of approach, even on the U-Boot level, a modification of the
      device tree is a prerequisite to have such modular families of boards
      supported properly.
      
      Therefore, we add an option to make the U-Boot device tree (the actual
      copy later used by the driver model) writeable, and add a callback
      method that allows boards to modify the device tree at an early stage,
      at which, hopefully, also the application of device tree overlays will
      be possible.

      spl: Setup default value for OF_LIST · c409bd01
      Michal Simek authored
      OF_LIST can't remain empty that's why setup it up to default DTB.
      
      If it is empty u-boot.img is created without FDT partition:
      For example:
        ./tools/mkimage -f auto -A arm -T firmware -C none -O u-boot -a
      0x8000000 -e 0 -n "U-Boot 2016.05-rc3 ..." -E -b  -d u-boot-nodtb.bin u-boot.img
      Can't set 'timestamp' property for '' node (FDT_ERR_NOSPACE)
      FIT description: Firmware image with one or more FDT blobs
      Created:         Wed May  4 15:02:52 2016
       Image 0 (firmware@1)
        Description:  U-Boot 2016.05-rc3-00080-gff2e12ae22a8-dirty for zynqmp
      board
        Created:      Wed May  4 15:02:52 2016
        Type:         Firmware

       Configuration 0 (conf@1)
        Description:  unavailable
        Kernel:       unavailable
      
      And then image like this doesn't contain description and link to FDT and
      can't boot.
