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.

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".

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_MULTI

As discussed on the list, move "arch/ppc" to "arch/powerpc" to
better match the Linux directory structure.
Please note that this patch also changes the "ppc" target in
MAKEALL to "powerpc" to match this new infrastructure. But "ppc"
is kept as an alias for now, to not break compatibility with
scripts using this name.

Now that the other architecture-specific lib directories have been
moved out of the top-level directory there's not much reason to have the
'_generic' suffix on the common lib directory.

Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk
This change is intended to clean up the top-level directory structure
and more closely mimic Linux's directory organization.

According to the PPC reference implementation the udelay() function is
responsible for resetting the watchdog timer as frequently as needed.
Most other architectures do not meet that requirement, so long-running
operations might result in a watchdog reset.
This patch adds a generic udelay() function which takes care of
resetting the watchdog before calling an architecture-specific
__udelay().

* Remove symlinking of files located outside api_examples/
* Auto generate dependencies for files located outside api_examples/
* Update names of variables to be similar to those in tools/Makefile
* Fix out of tree build error
Dependencies are calculated for all files in the SRCS variable.
Previously, the SRCS variable contained files which were symlinked
into the api_examples/ directory. These symlinked files did not exist
when dependencies were calculated when building out of tree. This
resulted in errors such as:
make[1]: *** No rule to make target `/work/wd/tmp-ppc/api_examples/.depend', needed by `_depend'. Stop.
make[1]: Leaving directory `/home/wd/git/u-boot/work/api_examples'
make: *** [depend] Error 2
Since symlinked source files are no longer used, this bug no longer
exists.

This fixes a build breakage with CONFIG_API enabled, which appeared after
the recent changes in the U-Boot build system.

This is an API for external (standalone) applications running on top of
U-Boot, and is meant to be more extensible and robust than the existing
jumptable mechanism. It is similar to UNIX syscall approach. See api/README
for more details.
Included is the demo application using this new framework (api_examples).
Please note this is still an experimental feature, and is turned off by
default.
