In case that the new toolchains don't work well, we can trace back
and reproduce the old tools by checking the xgcc folder. It is useful
when my team members need to get my old toolchains on their own host
machines.

The common part of the bootblock resets the nvram data if it's found
to be invalid. Since that code is compiled with romcc in i386 mode,
there's a shortage on registers.
Try to reduce the strain by doing things smarter: cmos_write_inner
is the same as cmos_write, just that it doesn't check if the RTC is
disabled. Since we just disabled it before, we can assume that it is so.

For arm/snow, current bootblock is larger than previously assigned CBFS offset
and will fail to boot. To prevent this happening again in future, cbfstool now
checks if CBFS will overlap bootblock.
A sample error message:
E: Bootblock (0x0+0x71d4) overlap CBFS data (0x5000)
E: Failed to create build/coreboot.pre1.tmp.
arm/snow offset is also enlarged and moved to Kconfig variable.

This patch moves ARM core and DRAM timing functions around to simplify
the dependencies for system_clock_init().
The original code was architected such that the system_clock_init()
function called other functions to obtain core and memory timings.
Due to the way memory timing information must be obtained on Snow,
which entails decoding platform-specific board straps, the bottom-
up approach resulted in having the low-level clock init code
implicitly depend on board and vendor-specific info:
main()
->system_clock_init()
-> get_arm_ratios()
-> CPU-specific code
-> clock_get_mem_timings()
-> board_get_revision()
-> read GPIOs (3-state logic)
-> Decode GPIOs in a vendor-specific manner
-> Choose memory timings from module-specific look-up table
...then proceed to init clocks
...come back to main()
The new approach gathers all board and vendor-specific info in a
more appropriate location and passes it into system_clock_init():
main()
-> get_arm_ratios()
-> CPU-specific code
-> get_mem_timings()
-> board_get_config()
-> read GPIOs (3-state logic)
-> Decode GPIOs in a vendor-specific manner
-> Choose memory timings from module-specific look-up table
-> system_clock_init()
...back to main()

Right now cbfstool only accepts firmware volumes with
a x86 SEC core and refuses an x86-64 SEC core because
some magic values and the extended PE header are
different. With this patch, both IA32/x64 images are
supported. (No check is done whether the mainboard
actually supports 64bit CPUs, so careful!)
This needs another patch to Tiano Core that switches
to long mode after jumping to the 64bit entry point.
Right now that code assumes we're already in 64bit code
and the machine crashes.

Usage Changes: To support platforms with different memory layout, "create" takes
two extra optional parameters:
"-b": base address (or offset) for bootblock. When omitted, put bootblock in
end of ROM (x86 style).
"-H": header offset. When omitted, put header right before bootblock,
and update a top-aligned virtual address reference in end of ROM.
Example: (can be found in ARM MAkefile):
cbfstool coreboot.rom create -m armv7 -s 4096K -B bootblock.bin \
-a 64 -b 0x0000 -H 0x2040 -o 0x5000

Current cbfstool implementation is relying on global variables to pass processed
data, and the calculation of address is based on x86 architecture (ex, always
assuming 0x0000 as invalid address), not easy to be used on platforms without
top-aligned memory mapping. This CL is a first step to start a new cbfstool
without global variables, and to prevent assuming memory layout in x86 mode.
The first published APIs are for reading and writing existing CBFS ROM image
files (and to find file entries in a ROM file).
Read cbfs_image.h for detail usage of each API function.

Many functions in cbfstool need to deal with a memory buffer - both location and
size. Right now it's made by different ways: for ROM image using global variable
(romsize, master_header); and in cbfs-* using return value for size and char**
to return memory location.
This may cause bugs like assuming incorrect return types, ex:
uint32_t file_size = parse(); // which returns "-1" on error
if (file_size <= 0) { ...
And the parse error will never be caught.
We can simplify this by introducing a buffer API, to change
unsigned int do_something(char *input, size_t len, char **output, ...)
into
int do_something(struct buffer *input, struct buffer *output, ...)
The buffer API will be used by further commits.

As argument you have to give it the COREBOOT.FD generated by
the Tianocore build system.
It automatically determines base address and entry point.
Compression setting is honored (ie. no compression if you don't
want), but corebootPkg currently assumes that coreboot is doing
it. Loading a 6MB payload into CBFS without compression will fail

This file has mostly (but not entirely) been replaced by coreboot
stage files. We'll keep it around for a bit longer as a reference,
but in the meantime we'll stop compiling it as to avoid comptilation
issues as we change other parts of the code.

Snow's AP, EC, PMU, and smarty battery share a bus. Both the AP and
EC can act as a master, so to avoid conflicts an arbitration
mechanism consisting of two GPIOs is used.
By default, the AP "owns" the bus unless it is off (in which case
the EC doesn't monitor the arbitration pins). This means the boot
firmware does not need to worry about these lines. The payload may
if it needs to communicate with the EC, though.
In any case, board-specific bus arbitration logic does not belong
in a low-level driver that is supposed to be generic for an entire
CPU family. If the payload needs to talk to the EC, we'll deal with
it there.

This removes some duplicate code from Snow's mainboard bootblock
by utilizing the bootblock build class.

This adds a helper function to read only a single GPIO which uses
3-state logic. Examples of this typically include board straps which
are used to provide mainboard-specific information at the hardware-
level, such as board revision or configuration options.
This is part of a larger clean-up effort for Snow. We may want to
genericise this for other CPUs in the future.

This adds /src/include/gpio.h which currently contains generic GPIO
enums for type (in/out/alt) and 3-state logic.
The header was originally written for another FOSS project
(code.google.com/p/mosys) and thus the BSD license.

The cpu_is_exynos5() macro seems broken at the moment, so skip it.
The macro is superfluous and will probably be replaced eventually,
but at least this will un-break usage sites.

For ARM platform, the bootblock may need more C source files to initialize
UART / SPI for loading romstage. To preventing making complex and implicit
dependency by using #include inside bootblock.c, we should add a new build class
"bootblock".
Also #ifdef __BOOT_BLOCK__ can be used to detect if the source is being compiled
for boot block.
For x86, the bootblock is limited to fewer assembly files so it's not using this
class. (Some files shared by x86 and arm in top level or lib are also changed
but nothing should be changed in x86 build process.)
