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 objWe 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.Signed-off-by: Masahiro Yamada

This commit changes the working directory
where the build process occurs.Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-bootHere, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.And our old build system changes the current working directory
with "make -C " syntax when descending into the
sub-directories.On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj="
syntax for descending into sub-directories.
(We can write it like "make $(obj)=" with a shorthand.)
This means the current working directory is always the top
of the output directory.Signed-off-by: Masahiro Yamada

This commit moves suffix rules from config.mk
to scripts/Makefile.build, which will allow us
to switch smoothly to real Kbuild.Note1:
post/lib_powerpc/fpu/Makefile has
its own rule to compile C sources.
We need to tweak it to keep the same behavior.Note2:
There are two file2 with the same name:
arch/arm/lib/crt0.S and eamples/api/crt0.S.
To keep the same build behavior,
examples/api/Makefile also has to be treaked.Signed-off-by: Masahiro Yamada

Commit fea25720 renamed arch/i386 to arch/x86.
But it missed to modify examples/standalone/Makefile.Since then, examples/standalone/82559_eeprom has
never compiled and nobody has noticed that.After some discussion on ML, we agreed to delete this example.

The standalone programs do not use the api calls, but rely
directly on u-boot variable gd->jt for the jump table. Commit
fe1378a - "ARM: use r9 for gd" changed the register holding
the address of gd, but the assembly code in the standalone
examples was not updated accordingly. This broke the programs
on ARM relying on the jumptable in the v2013.10 release.
This patch unbricks them by using the correct register.Cc: Michal Simek

All objects under api/ and examples/api/ directories are selected
by CONFIG_API.
So we can move CONFIG_API switch to the top Makefile.In order to use CONFIG_API, the definition of SUBDIR_EXAMPLES-y
must be moved after "sinlude $(obj)include/autoconf.mk".Signed-off-by: Masahiro Yamada

After further testing, this patch has two problems. First,
examples/standalone/Makefile was already inherting PLATFORM_LIBS from
the top-level Makefile so this lead to duplicating the private libgcc.
Second, currently the private libgcc has a reference to 'hang' that is
not being fulfilled.This reverts commit 4412db46468d5965da736d06f84d13e68a6e0b51.

U-Boot Makefiles contain a number of tests for compiler features etc.
which so far are executed again and again. On some architectures
(especially ARM) this results in a large number of calls to gcc.This patch makes sure to run such tests only once, thus largely
reducing the number of "execve" system calls.Example: number of "execve" system calls for building the "P2020DS"
(Power Architecture) and "qong" (ARM) boards, measured as:
-> strace -f -e trace=execve -o /tmp/foo ./MAKEALL
-> grep execve /tmp/foo | wc -lBefore: After: Reduction:
==================================
P2020DS 20555 15205 -26%
qong 31692 14490 -54%As a result, built times are significantly reduced, typically by
30...50%.Signed-off-by: Wolfgang Denk

The examples/api is not configured with USE_PRIVATE_LIBGCC. This makes
building examples/api break on certain boards that do not/cannot use the
public libgcc.Nevertheless, this patch has to also touch the top-level Makefile to fix
this problem because the current top-level Makefile does not specify
libgcc as a prerequisite of examples/api, and explicitly builds
examples/api _before_ libgcc.For testing this patch, I added the following to configs/seaboard.h and
ran demo.bin on a Seaboard.+#define CONFIG_API
+#define CONFIG_SYS_MMC_MAX_DEVICE 2
+#define CONFIG_CMD_NET
+#define CONFIG_NET_MULTISigned-off-by: Che-Liang Chiou

GNU Makefile have two flavors of variables, recursively expanded that is
defined by using '=', and simply expanded that is defined by using ':='.The bug is caused by using recursively expanded flavor for BIN and SREC.
As you can see below, they are prepended by $(obj) twice.We can reproduce this bug with a simplified version of this Makefile:
$ cat >Makefile <
