This change makes significant changes to cbmem.py to make it use the
coreboot tables to find the memory console and timestamp areas instead
of looking for the in memory table TOC structure. That appears to be
more robust and gets cbmem.py working again after some unrelated
changes that affected memory layout.
It also introduces some small infrastructure to make accessing C style
structures in physical memory easier and more transparent.

It looks like the cbfstool utility generates the output file even when
it fails to generate it properly. This causes make, if started second
time in a row, after cbfstool failure, to continue beyond the point of
failure (as the corrupted output file is present in the output tree,
the second make invocation presumes that it is valid, as it is newer
than the dependencies).
The output file should be created only when successful, in an atomic
operation. There could be other places in the make system which
require a similar fix, this needs to be investigated further.

The section created by this change needs to be stripped out by the Makefile

The CBMEM console driver saves console output in a CBMEM area, which
then is made available to Linux applications for perusing.
There are some system limitations which need to be worked around
to achieve this goal:
- some console traffic is generated before DRAM is initialized,
leave alone CBMEM initialized.
- after the RAM based stage starts, a lot of traffic is generated
before CBMEM is initialized.
As a result, the console log lives in three different places -
the bottom of the cache as RAM space, the CBMEM buffer (where it
is expected to be) and a static buffer used early in the RAM
stage.
When execution starts (in the cache as RAM mode), the console
buffer is allocated at the bottom of the cache as RAM memory
address range. Once DRAM is initialized, the CBMEM structure is
initialized, and then the console buffer contents are copied from
the bottom of the cache as RAM space into the CBMEM area right
before the cache as RAM mode is disabled. The
src/lib/cbmem_console.c:cbmemc_reinit() takes care of the
copying.
At this point the cache as RAM memory is about to be disabled,
but the ROM stage is still going generating console output. To
make sure this output is not lost, cbmemc_reinit() saves the new
buffer address at a fixed location (0x600 was chosen for this),
and the actual "printing" function checks to see if the RAM is
already initialized (the stack is in RAM), and if so, gets the
console buffer pointer from this location instead of using the
cache as RAM address.
When the RAM stage starts, a static buffer is used to store the
console output, as the CBMEM buffer location is not known. Then,
when CBMEM is reinitialized, cbmemc_reinit() again takes care of
the copying.
In case the allocated buffers are not large enough, the excessive
data is dropped, and the copying routine adds some text to the
output buffer to indicate that there has been data lost and how
many characters were dropped.

Also, since the CBMEM area could already contain a section (from the

request we should check if a section already exists and return its
