Make printf and vprintf safe from buffer overruns

Add safe vsnprintf and snprintf library functions
From: Sonny Rao <sonnyrao@chromium.org>
These functions are useful in U-Boot because they allow a graceful failure
rather than an unpredictable stack overflow when printf() buffers are
exceeded.
Mostly copied from the Linux kernel. I copied vscnprintf and
scnprintf so we can change printf and vprintf to use the safe
implementation but still return the correct values.

tools/setlocalversion: Update from the Linux Kernel
Several bugfixes have occurred upstream since this script was imported
into U-Boot. In particular, the script currently in U-Boot does not
describe commit f8bbb4dad0e9d91b7a51d6cc54dcf66d142f50fe correctly,
resulting in a version of "2011.09" instead of "2011.09-01460-gf8bbb4d".
With that commit checked out, the command "git name-rev --tags HEAD"
gives this result:
HEAD tags/v2011.12-rc1~30^2
Then the "changes" regex does not match because of the trailing '^2':
grep -E '^HEAD[[:space:]]+(.*~[0-9]*|undefined)$'
The new version of tools/setlocalversion in the kernel correctly handles
those situations by using different plumbing commands.
The version from the kernel is not directly usable as it does not append
the full GIT version that U-Boot expects unless the right config options
are set (CONFIG_LOCALVERSION_AUTO=y). Other than a few minor changes
for Kconfig, the imported version is very similar to Linux v3.2-rc4.

where the previous behavior of leaving wMaxPacketSize be unaligned

however as it showed another cases of non-aligned access that previously
worked implicitly. This switches to making sure that all access of
wMaxPacketSize are done via (get|put)_unaligned.
In order to maintain a level of readability to the code in some cases
we now use a variable for the value of wMaxPacketSize and in others, a

This is a cleaner detection method since EEPROM addresses
can be different on different board revisions. This also

post: fix compile issue for post tests on kirkwood
commit f31a911fe (arm, post: add missing post_time_ms for arm)
enables get_ticks and get_tbclk for all arm based boards,
but kirkwood has currently no implementation for this. So
undefine this for kirkwood boards.
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:

S5PC2XX: Rename S5pc2XX to exynos
As per new naming convention for Samsung SoC's, all Cortex-A9 and Cortex-A15
based SoC's will be classified under the name Exynos. Cortex-A9 and Cortex-A15
based SoC's will be sub-classified as Exynos4 and Exynos5 respectively.
In order to better adapt and reuse code across various upcoming Samsung Exynos
based boards, all uses of s5pc210 prefix/suffix/directory-names are renamed in
this patch. s5pc210 is renamed as exynos4210 and S5PC210/s5pc210 suffix/prefix

tegra2: Don't use board pointer before it is set up
In board_init_f() the gd->bd pointer is not valid when dram_init() is called.
This only avoids dying because DRAM is at zero on Tegra2. The common ARM
routine sets up the banks in the same way anyway, so we can just remove this
code.

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.

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.

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().

... rather than open-coding the register accesses.
However, gpio_request() typically stores the "label" parameter in a global

string to gpio_request(), and modify gpio_request() not to touch the string

tegra2: Move board_mmc_init into board files
For Seaboard, this is mostly a cut/paste of board_mmc_init() and
pin_mux_mmc() into seaboard.c; pin_mux_mmc() was modified to add some
missing pinmux_tristate_disable calls for the GPIOs.
For Harmony, those functions were modified to configure SDMMC2 (index 2)
instead of SDMMC3 (index 1), since that's what is present on the board.
However, harmony.c is still missing the required GPIO setup, so neither
port is likely to function correctly yet. This will be fixed in the next
change.
