This patch is twofold.
1. Improves the low level ecc memcpy code to better
specify that we're reading/writing buffers with ecc bytes.
2. Improves/creates the libflash interfaces for ecc.
This patch also includes some tests

With some fun Makefile rules, we can pick up all CCAN unit tests.
We exclude the unit test source files from the lcov report itself.
Add skeleton ccan config.h and tap.h that are enough for us to build
and run the test suite. Currently, the minimalist versions should
be fine (and we don't need CCAN configurator).
Also includes -Werror fixes for ccan tests.

Just calls OPAL_CONSOLE_WRITE with "Hello World!" and with mambo
we can execute this tiny boot test in not much time at all.
Good little sanity check.

We grab a version from git tags (or SKIBOOT_VERSION environment variable),
optionally tack on EXTRA_VERSION (if from git) as well as add things to the
git version number if we're ahead of the most recent tag or the tree is dirty.
Also fix-up makefiles so that we don't have to rebuild version.c every time
you run make.
fsp attn area needed updating as we can have >40 character version strings.
We also export the version string via device tree rather than just the gitid.
For buildroot builds, setting SKIBOOT_VERSION environment variable to the
tag you grab will do the correct thing.

In order to support fsp-less machines we need to be able to log errors
using a BMC or some other mechanism. Currently the error logging code
is tightly coupled to the platform making it difficult to add
different platforms.
This patch factors out the generic parts of the error logging code in
preparation for adding different logging backends. It also adds a
generic mechanism for pre-allocating a specific number of objects.

The PEL log format is not specific to the FSP. We plan to use the same
format for OpenPOWER systems. This patch refactors the code into a
platform agnostic file.

Add support in core/test/Makefile.check to build -gcov
binaries (with -lgcov and -fprofile-blah-blah) as well
as some targets for producing lcov HTML code coverage reports.
As part of this, I had to fix up an oddity in run-mem_region_init
where that due to running under Valgrind, we'd be malloc()ed a
heap with a small address, well inside the mem_regions we added but
when not running under valgrind (e.g. for code coverage reporting)
we would get a much larger address, outside this range and hit
an assert. So, after fiddling with the memory stuff for this test,
I think I have it right - it passes both under valgrind and not and
does produce code coverage data.
Currently, we're at this level of code coverage by unit tests:
Hit Total Coverage
Lines: 1936 2574 75.2 %
Functions: 177 225 78.7 %
Branches: 1243 2360 52.7 %
The totals should largely be ignored due to the only code being
counted is that linked into the unit tests (total LOC is ~50kLOC
according to sloccount... so unit tests currently cover < 5%)
Try the "make coverage-report" target, you'll get coverage-report
directory with a LCOV HTML report
