commit 0d479b53 (Aneesh V) added code for OMAP4 that doesn't

076cd49ad1 arm926ejs: remove noop flush_dcache_all function
Commit 2f3427c added noop cache functions implementation for arm926ejs
to fix compilation of drivers depending on these functions (DaVinci
EMAC in particular).

Unfortunately, the bug was introduced: noop implementation calls
dcache_disable which calls flush_dcache_all which in turn calls
dcache_disable thus creating an infinite loop.

This patch removes noop implementation for flush_dcache_all, we already
have default one in arch/arm/lib/cache.c and it should be used instead.

69370d144a x86: Refactor the zboot innards so they can be reused with a vboot image
If vboot successfully verifies a kernel, it will leave it in place and
basically ready to boot. The zeropage table which is part of the x86 boot
protocol is at the end of the kernel, though, instead of the beginning, and
because the image is already in place there's no need to copy it around.
This change refactors the code which implements the zboot command so that
the configuration of the zeropage table and loading the pieces of the
kernel into memory are done separately. Also, because the command line goes
before the zeropage table in vboot which is somewhat incompatible with the
normal protocol, where to put the command line is a now a parameter instead
of being hard coded.

63f559cd12 x86: Import code from coreboot's libpayload to parse the coreboot table
This change also forces the lib_sysinfo structure to be in the .data
section. Otherwise it ends up in the .bss section. U-boot assumes that it
doesn't need to copy it over during relocation, and instead fills that
whole section with zeroes. If we really were booting from ROM that would be
appropriate, but we need some information from the coreboot tables (memory
size) before then and have to fill that structure before relocation. We
skirt u-boot's assumption by putting this in .data where it assumes there
is still read only but non-zero data.

3b2001105f powerpc/bootm: Flush ramdisk and device tree image when booting on MP
We already flush the kernel image after we've loaded it to ensure
visiblity to the other cores.  We need to do the same thing for the
ramdisk and device tree images.  In AMP boot scenarios we might not be
HW cache coherent with the secondary core that we are loading and
setting the ramdisk and device tree up for.  Thus we need to ensure
we've flushed the regions of memory utilized by ramdisk and device tree
so the loadding and any modifications (from decompression or fdt updates)
are made visible to the secondary cores.

f8d2c65fd9 sandbox: fix compiling of cpu/os.c
U-boot itself generally builds with -nostdinc.  This is because the
bootloader needs to be completely standalone.  In the sandbox arch
though, we need a little bit of code to glue the u-boot world to the
host operating system, and we need to be able to access the host
libc's headers in order to do so.

Currently, we're using -I/usr/include to workaround the global
-nostdinc, but that doesn't work for everyone and for all headers.
Instead, let's filter out -nostdinc when building the os.c code.

Without this patch, some distros hit errors such as:
---8<---

8ba1604d34 M28: Cleanup memsize.o OOT build
The current way memsize.c is built just made a symlink into the directory
with SPL and then compiled it like any other file there. This was bad as that
broke the out-of-tree build.

The new way introduced in this patch uses the standard spl/Makefile methods
(CONFIG_SPL_LIBCOMMON_SUPPORT / CONFIG_SPL_LIBGENERIC_SUPPORT) to let files in
common/ be built. Because common/Makefile says memsize.c is always built (SPL
and non-SPL build), this fixes our issue with memsize.c out-of-tree build.

80433c9ac6 arm: Move CP15 init out of cpu_init_crit()
Some SOCs have do not start up with their 'main' CPU. The first U-Boot
code may then be executed with a CPU which does not have a CP15, or not a
useful one.

Here we split the initialization of CP15 into a separate call, which can
be performed later if required.

Once the main CPU is running, you should call cpu_init_cp15() to perform
this init as early as possible.

Existing ARMv7 boards which define CONFIG_SKIP_LOWLEVEL_INIT should not
need to change, this CP15 init is still skipped in that case. The only
impact for these boards is that the cpu_init_cp15() will be available
even if it is never used on these boards.

210576fc5e tegra2: Simplify tegra_start() boot path
The Tegra2 boot path is more complicated than it needs to be. Since we want
to move to building most of U-Boot with ARMv7 and only a small part with
ARMv4T (for AVP) it should be as simple as possible.

This makes tegra2_start() into a simple function which either does AVP
init or A9 init depending on which core is running it. Both cores now
following the same init path, beginning at _start, and the special Tegra2
boot path code is no longer required.

Only two files need to be built for ARMv4T, and this is handled in the
Tegra2 CPU Makefile.

e43d6ed932 tegra2: Add arch_cpu_init() to fire up Cortex-A9
We want to move away from a special Tegra2 start-up, and just use
arch_cpu_init() instead. However, if we run board_init_f() from boot
we need to build it for ARMv4T, since the Tegra's AVP start-up CPU
does not support ARMv7.

The effect of this is to do the AVP init earlier, and in
arch_cpu_init(), rather that board_early_init_f().

01baa05643 powerpc: Minimal private libgcc to build on Debian
Standard Debian powerpc and powerpcspe systems only include hard-float
libgcc in their native compilers, which causes scary build warnings when
building U-Boot.

Debian and other PowerPC-supporting distributions used to provide libgcc
and other libraries in a "nof" (soft-float) form in the "multilib"
packages.  As they were completely unused by the distribution and
therefore tended to be very buggy it was decided to save some time on
the part of the maintainers and build-servers by removing them.

Admittedly, right now the linker warnings do not indicate any problems,
as the included routines do not use any floating point at all.

The concern is that if floating-point code were ever added it might
cause hard-float code to be unexpectedly included in U-Boot without
generating a hard error.  This would cause unexplained crashes or
indeterminate results at runtime.

The easiest way to resolve this is to borrow the routines that U-Boot
needs from the Linux kernel, which has the same issue.

Specifically, the routines are: _ashldi3(), _ashrdi3(), and _lshrdi3().
They were borrowed from arch/powerpc/kernel/misc_32.S as of v2.6.38-rc5,
commit 85e2efbb1db9a18d218006706d6e4fbeb0216213, and are GPLv2+.

The Makefile framework was copied from the U-Boot ARM port.
