Before this commit, USE_PRIVATE_LIBGCC was defined in
arch-specific config.mk and referenced in
arch/$(ARCH)/lib/Makefile.
We are not happy about parsing config.mk again and again.
We have to keep the same behavior with a different way.
By adding "CONFIG_" prefix, this macro appears
in include/autoconf.mk, include/spl-autoconf.mk.
(And treating USE_PRIVATE_LIBGCC as CONFIG macro
is reasonable enough.)
Tegra SoC family defined USE_PRIVATE_LIBGCC as "yes"
in arch/arm/cpu/arm720t/tegra*/config.mk,
whereas did not define it in arch/arm/cpu/armv7/tegra*/config.mk.
It means Tegra enables PRIVATE_LIBGCC only for SPL.
We can describe the same behavior by adding
#ifdef CONFIG_SPL_BUILD
# define CONFIG_USE_PRIVATE_LIBGCC
#endif
to include/configs/tegra-common.h.

The Qemu specific bootm implementation was intended for a special
Qemu target in Linux kernel. But this target has been dropped in
v2.6.25-rc1 by commit 302922e5f6901eb6f29c58539631f71b3d9746b8

[MIPS] Qemu: Remove platform.
The Qemu platform was originally implemented to have an easily supportable
platform until Qemu reaches a state where it emulates a real world system.
Since the latest release Qemu is capable of emulating the MIPSsim and
Malta platforms, so this goal has been reached. The Qemu plaform is also
rather underfeatured so less useful than a Malta emulation.
Thus the special bootm implementation is obsolete by now and can be
dropped. The Qemu support in U-Boot is going to be replaced by MIPS Malta
board support.

Import ashldr3, ashrdi3 and lshrdi3 to squash possible libgcc fp mismatch,
resulting in the following warning:
mips-linux-gnu-ld: Warning: /usr/lib/gcc/mips-linux-gnu/4.7/libgcc.a(_lshrdi3.o) uses hard float, u-boot uses soft float

[MIPS] Fix optimization for size build.
It took a while longer than on other architectures but gcc has finally
started to strike us as well ...
This also fixes the damage by 6edfba1b33c701108717f4e036320fc39abe1912.

Current timer routines (arch/mips/lib/timer.c) are implemented assuming
that MIPS32 coprocessor (CP0) resources, Counter and Compare registers
in this case, are available. But this doesn't always work.
We need to make sure that all MIPS-based systems don't necessarily use
CP0 counter/compare registers as time keeping resources. And some MIPS
variant processors might come with different hardware specs with genuine
MIPS32 CP0 registers.
With this change, each $(CPU)/ directory can have its own timer code.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils. As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".
This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.
The name of each former library archive is preserved except for
extensions which change from ".a" to ".o". This commit updates
references accordingly where needed, in particular in some linker
scripts.
This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols. Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

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.
