This is a bit of a hack but it's very handy. It compiles in your static.c
and then shows what coreboot would see when it is run. It uses your static.c
and functions pulled from src/device/device_util.c.
I've already used it to debug problems with the snow device tree.

Current cbfstool implementation is relying on global variables to pass processed

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.

files (and to find file entries in a ROM file).

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.

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 |--------------|
| bootblock |
|--------------|
TODO: The option for alignment passed into cbfstool has always been
64. Can we set it to 16 instead?

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/

This tidies up the ARMV7 case when creating cbfs:
- Calculate the offset using the size of the master header and offsets
rather than using a magic constant.
- Re-order some assignments so things happen in a logical order.
