Coreboot and u-boot create a table of timestamps which allows to see
the boot process performance. The util/cbmem/cbmem.py script allows to
access the table after ChromeOS boots up and display its contents on
the console. The problem is that shipping images do not include Python
interpreter, so there is no way to access the table on a production
machine.
This change introduces a utility which is a Linux app displaying the
timestamp table. Conceivably the output of this utility might be
included in one of the ChromeOS :/system sections, so it was attempted
to write this procedure 'fail safe', namely reporting errors and not
continuing processing if something goes wrong.
Including of coreboot/src .h files will allow to keep the firmware
timestamp implementation and this utility in sync in the future.
Test:
. build the utility (run 'make' while in chroot in util/cbmem)
. copy `cbmem' and 'cbmem.py' to the target
. run both utilities (limiting cbmem.py output to 25 lines or so)
. observe that the generated tables are identical (modulo rounding
up of int division, resulting in 1 ns discrepancies in some
cases)

Detailed timing descriptor (DTD) is an 18 byte array describing video

ROM. Option ROM can support multiple video modes, specific mode is
picked by the BIOS through the appropriate Option ROM callback
function.
The new utility allows to interpret the 18 byte hex DTD dump, and/or
modify certain values, and generate a new DTD.
To parse the DTD contents just pass the 18 bytes to the utility in the
command line. To modify the existing contents and generate a new dump
precede the 18 bytes with '-m' and follow prompts.

For some reason which I fail to understand, specifying endiannes using
'@' (which means 'native' and should be the same as '<' on x86
platforms) causes cbmem.py to crash the machine on 64 bit systems.
What happens is that the addresses read from various table headers'
struct representations do not make sense, when bogus address gets
passed to get_phys_mem, the crash happens while that function is
executed.
dlaurie@ found out that replacing "@" with "<" in fact fixes the
issue. After some investigation I am just submitting this fix without
much understanding of the root cause.

CBFS allows coreboot rom images that are only partially covered
by the filesystem itself. The intention of this feature was to
allow EC / ME / IMC firmware to be inserted easily at the beginning
of the image. However, this was never implemented in cbfstool.
This patch implements an additional parameter for cbfstool.
If you call cbfstool like this:
cbfstool coreboot.rom create 8192K bootblock.bin 64 0x700000
it will now create an 8M image with CBFS covering the last 1M of
that image.
Test:
cbfstool coreboot.rom create 8192K bootblock.bin 64 0x700000
creates an 8M image that is 7M of 0xff and 1M of CBFS.
