This breaks booting, and in fact stages.c is always going to be special: for it to work it has to be compiled for arm only, no thumb allowed. It's probably better to leave the stages.o target in explicitly so it's clear that it has to be compiled with a particular set of flags, rather than try to remember that we must always have the default rules no break stages.c compilation. That would be a mess. I will be pushing a CL to get rid of the assembly dump, but will be a trivial fix.

These were not separable or it would have been two CLs.
Enable CHROMEOS configure option on snow. Write gpio support code for
the mainboard. Right now the GPIO just returns hard-wired values for
"virtual" GPIOs.
Add a chromeos.c file for snow, needed to build.
This is tested and creates gpio table entries that our hardware can use.
Lots still missing but we can now start to fill in the blanks, since
we have enabled CHROMEOS for this board. We are getting further into
the process of actually booting a real kernel.

Payloads, by design, can return. There's lots of mechanism in the payload code
to support it, and the chooser payload relies on it. Hence, we should not mark
the function call in exit_stage as noreturn.
Not all ARM have unified caches, and it's not always easy to tell what
to do. So we are very paranoid. Before we call between stages, we
should carefully flush the dcache to memory and invalidate the icache.
This may be more than is necessary on all architectures but it
doesn't really hurt for the most part.
So compile cache management code into all stages, and call the
flush dcache/invalidate icache from all stages.

This patch fixes up the usage of stack pointer and regions.
The current approach only works by coincidence, so this fixes a few
things at once to get it into a working state and allow us to use
checkstack() again:
- Add a STACK_SIZE Kconfig variable. Earlier on it was evaluated to 0.
- Assign _stack and _estack using CPU-specific Kconfig variables since
it may reside elsewhere in memory (not necessarily DRAM).
- Make the existing IRAM stack variables more useful in this context.

RAMBASE and RAMTOP are leftovers from the x86 port and do not apply
the same way on ARM platforms. On x86 they refer to the low memory
region where coreboot tables reside.
However on ARM we don't have such a region which is architecturally
defined. So instead we'll use the CPU-defined DRAM base address and
the mainboard-defined DRAM size.
This also has the pleasant side-effect of fixing the coreboot tables
to not clobber ramstage code...

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
Verified to boot on ARM (Snow) and X86 (QEMU).

To support platforms without top-aligned address mapping like ARM, "locate"
command now outputs platform independent ROM offset by default. To retrieve x86
style top-aligned virtual address, add "-T".
To test:
cbfstool coreboot.rom locate -f stage -n stage -a 0x100000 -T
# Example output: 0xffffdc10

This unplugs Stefan's PIANO project.
Change Tianocore payload configuration to use corebootPkg.
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
more often than not.

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.)

Summary:
Isolate CBFS underlying I/O to board/arch-specific implementations as
"media stream", to allow loading and booting romstage on non-x86.
CBFS functions now all take a new "media source" parameter; use
CBFS_DEFAULT_MEDIA if you simply want to load from main firmware.
API Changes:
cbfs_find => cbfs_get_file.
cbfs_find_file => cbfs_get_file_content.
cbfs_get_file => cbfs_get_file_content with correct type.
CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM,
the ROM may come from USB, UART, or SPI -- any serial devices and not available
for memory mapping.
To support these devices (and allowing CBFS to read from multiple source
at the same time), CBFS operations are now virtual-ized into "cbfs_media". To
simplify porting existing code, every media source must support both "reading
into pre-allocated memory (read)" and "read and return an allocated buffer
(map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*"
provides simple memory mapping simulation.
Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA
is defined for CBFS functions to automatically initialize a per-board default
media (CBFS will internally calls init_default_cbfs_media). Also revised CBFS
function names relying on memory mapped backend (ex, "cbfs_find" => actually
loads files). Now we only have two getters:
struct cbfs_file *entry = cbfs_get_file(media, name);
void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type);
Test results:
- Verified to work on x86/qemu.
- Compiles on ARM, and follow up commit will provide working SPI driver.

This makes extra step (prefix 0x, and then generate another temp file) in build

This patch does a few things to get us into romstage:
- Add romstage as a stage (a later patch adds it as a binary, which
is probably wrong). The Makefile magic is complex enough that we
let it build the XIP file for now, but we no longer use it.
- Replace findstage with loadstage. Loadstage will find a stage,
load the code to memory, and zero the remaining part of memory.
Now we can link the romstage to go anywhere!
- Eliminate magic offsets from code/ldscripts and centralize Kconfig
variables in src/cpu/samsung/exynos5250/Kconfig.
- Tidy up code and serial output

This adds a wrapper around main() in romstage which is compiled using
-marm. This assumes that the bootblock branches to romstage in ARM
mode.
The long-term idea is to enforce ABI compatibility when handing off to
the next stage by using shims which are which are compiled in a pre-
determiend manner and leave the main portions of each stage up to
whatever the compiler wants. So it will eventually look like this:
1. bootblock_main (ARM/Thumb)
2. bootblock_exit (ARM)
3. romstage_entry (ARM)
4. romstage_main (ARM/Thumb)

- UART, including requisite I2C, Maxim PMIC, and clock config code.
- Adjustments for magic offsets (id section, stack pointer address)
This is just a temporary solution until we have romstage loading.
Once that happens, we'll rip out all but the code necessary for

This replaces hard-coded bootblock offsets using the new scheme.
The assembler will place the initial branch instruction after BL1,
skip 2 aligned chunks, and place the remaining bootblock code after.
It will also leave an anchor string, currently 0xdeadbeef which
cbfstool will find. Once found, cbfstool will place the master CBFS
header at the next aligned offset.
Here is how it looks:
0x0000 |--------------|
| BL1 |
0x2000 |--------------|
| branch |
0x2000 + align |--------------|
| CBFS header |
0x2000 + align * 2 |--------------|

In order to provide some insight on what code is executed during
coreboot's run time and how well our test scenarios work, this
adds code coverage support to coreboot's ram stage. This should
be easily adaptable for payloads, and maybe even romstage.
See http://gcc.gnu.org/onlinedocs/gcc/Gcov.html for
more information.
To instrument coreboot, select CONFIG_COVERAGE ("Code coverage
support") in Kconfig, and recompile coreboot. coreboot will then
store its code coverage information into CBMEM, if possible.
Then, run "cbmem -CV" as root on the target system running the
instrumented coreboot binary. This will create a whole bunch of
.gcda files that contain coverage information. Tar them up, copy
them to your build system machine, and untar them. Then you can
use your favorite coverage utility (gcov, lcov, ...) to visualize
code coverage.
For a sneak peak of what will expect you, please take a look
at http://www.coreboot.org/~stepan/coreboot-coverage/

Since coreboot is compiled into 32bit code, and userspace
might be 32 or 64bit, putting a pointer into the coreboot
table is not viable. Instead, use a uint64_t, which is always

Our reference toolchain uses -mabi=aapcs whereas we started
forcing -mabi=aapcs-linux. Drop this to prevent ABI incompatibility.
Also drop -fno-common since that's set in the top level Makefile.inc

There was a misuse of bool that would cause the dcache policy to not be
set up correctly, but instead present options "y" and "n" in the Kconfig
menu.
Also, TINY_BOOTBLOCK was removed a while ago, everything is
TINY_BOOTBLOCK now. Hence remove the option.

This updates $CFLAGS used for armv7. Most of them were just added
to be consistent with what u-boot does. The important ones here
are -march=armv7-a and -mthumb (to allow 16-bit Thumb instructions).
I removed the hard float support because it got errors and
coreboot should never use floats anyway. We're still having trouble
with enums but I want to see how far it gets with this patch.
Also, put the flags in a form that makes diffs easier to read. It's
almost impossible otherwise.
Finally, move some flags to the architecture Makefile, and
rely on the fact that some are set for all architectures.

The old start.S file did a lot of work and had AP-specific #ifndef's.
The new init.S will eventually contain only bare minimum generic ARM
code for use by the bootblock. Processor-specific stuff and things
that take place later in the boot process should go elsewhere.
