Patch f33b9bd3
[arm: omap3: Enable clocks for peripherals only if they are used]
breaks SPL booting on tao3530. Since some gpio input's are
read to detect the board revision. But with this patch above, the
clocks to the GPIO subsystems are not enabled per default any more.
The GPIO banks need to be configured specifically now.

This patch add support for the Silica Pengwyn board [1]
The board is based on a TI AM3354 CPU [2]
All jumpers removed it will boot from the SDcard, the console is on
UART1 accessible via the FDTI -> USB. The on board NAND flash is
supported and can act as boot medium, depending on jumper settings.
USB Host, USB Device and Ethernet are also provided but untested.

It is convenient to have all device trees on the same SoC compiled.
It allows for later easy repackaging without the need to re-run

Unlike Linux Kernel, U-Boot historically had *.dts files under
board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/.

I think arch/$(ARCH)/dts dicretory is a better location
to store both *.dts and *.dtsi files.

For example, before this commit, board/xilinx/dts directory
had both Microblaze dts (microblaze-generic.dts) and
ARM dts (zynq-*.dts), which are totally unrelated.

This commit moves *.dts to arch/$(ARCH)/dts/ directories,
allowing us to describe nicely mutiple DTBs generation in the next commit.

fw_printenv is a program which mostly runs on the target Linux.

Before switching to Kbuild, we needed to set HOSTCC at the
command line like this:

    make CROSS_COMPILE=<your cross-compiler prefix> env

We had switched to Kbuild, so we do not need to
delete sandburst board files at every build.

U-Boot conventional build system did not check the

when command line options are changed.
(The file ".*.cmd" stores the information how the file
was generated at the previous build.)

  - Create a Makefile in the output directory
Signed-off-by: NMasahiro Yamada <yamada.m@jp.panasonic.com>

This commit fixes two problems:

[1] We could not do board configuration and "make all"
    in one command line.

For example, the following did not work as we expect:
  $ make sandbox_config all
  Configuring for sandbox board...
  make: Nothing to be done for `all'.

[2] mixed-target build did not work with -j option

For example, the following did not work:
  $ make -j8 sandbox_config u-boot
  Makefile:481: *** "System not configured - see README".  Stop.
  make: *** [u-boot] Error 2
  make: *** Waiting for unfinished jobs....
  Configuring for sandbox board...

Going forward, we can do
  $ make -j8 sandbox_config all

This is the same as
  $ make sandbox_config
  $ make -j8

This commit changes the top Makefile to handle various targets
nicely.
Make targets are divided into four categories:

 - mixed-targets
     We can call a configuration target and build targets
     at one command line like follows:
     $ make <board_name>_config u-boot

     They are handled one by one.

 - config targets
     <board_name>_config

 - no-dot-config-targets
     Targets we can run without board configuration such as
       clean, mrproper, distclean, TAGS, %docs, etc.

 - build targets
     The other target which need board configuration.

This commit changes the location of include directives
of board configuration files.

The purpose of this change is:
 - Slim down $(TOPDIR)/config.mk
 - Prevent $(TOPDIR)/Makefile from including the same
    configuration file twice
 - Do not include include/config.mk multiple times
    because ARCH, CPU, BOARD, VENDOR, SOC are exported

Before this commit:

 - include/autoconf.mk was included from $(TOPDIR)/Makefile
   and $(TOPDIR)/config.mk
   (This means $(TOPDIR)/Makefile included include/autoconf.mk twice)

 - include/{spl,tpl}-autoconf.mk was included from $(TOPDIR)/config.mk

 - include/config.mk was included from $(TOPDIR)/Makefile
   and $(TOPDIR)/config.mk
   (This means $(TOPDIR)/Makefile included include/config.mk twice)

After this commit:

 - include/autoconf.mk is included from $(TOPDIR)/Makefile
   and $(TOPDIR)/scripts/Makefile.build

 - include/{spl,tpl}-autoconf.mk is included from $(TOPDIR)/spl/Makefile
   and $(TOPDIR)/scripts/Makefile.build

 - include/config.mk is included from $(TOPDIR)/config.mk and
   $(TOPDIR)/spl/Makefile

We had switched to Kbuild.
We do not need old build scripts any more.
Signed-off-by: NMasahiro Yamada <yamada.m@jp.panasonic.com>

Now we are ready to switch over to real Kbuild.

This commit disables temporary scripts:
  scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
  scripts/{Makefile.build,Makefile.host,Makefile.lib}.

This switch is triggered by the line in scripts/Kbuild.include
  -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
  +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj

We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.

Additionally, we need to fix compiler flags which are
locally added or removed.

In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.
