Several small improvements of the stack checking code:
- move the CPU0 stack check right before jumping to the payload
and out of hardwaremain (that file is too crowded anyways)
- fix prototype in lib.h
- print size of used stack
- use checkstack function both on CPU0 and CPU1-x
- print amount of stack used per core

In hardwaremain() we can't add timestamps before we actually
reinitialized the cbmem area. Hence we kept the timestamps in
an array and added them later. This is ugly and intrusive and
helped hiding a bug that prevented any timestamps to be logged
in hardwaremain() when coming out of an S3 resume.
The problem is solved by moving the logic to keep a few timestamps
around into the timestamp code. This also gets rid of a lot of ugly
ifdefs in hardwaremain.c

This addition is in support of future multicore support in
coreboot. It also will allow us to remove some asssembly code.
The CPU "index" -- i.e., its order in the sequence in which
cores are brought up, NOT its APIC id -- is passed into the
secondary start. We modify the function to specify regparm(0).
We also take this opportunity to do some cleanup:
indexes become unsigned ints, not unsigned longs, for example.
Build and boot on a multicore system, with pcserial enabled.
Capture the output. Observe that the messages
Initializing CPU #0
Initializing CPU #1
Initializing CPU #2
Initializing CPU #3
appear exactly as they do prior to this change.

This change allows us to figure out how much of the AP stacks we are
using, as well as to catch any case of an AP overrunning its stack.
Also, the stack is poisoned, which is a good way to catch programming
errors -- code should never count on auto variables being zerod.
The stack bases are recorded in a new array, stacks. At the end,
when all APs are initialized, the stacks are walked and the
lowest level of the stack that is reached is printed.
Build and boot and look for output like this:
CPU1: stack allocated from 00148000 to 00148ff4:\
lowest stack address was 00148c4c
CPU2: stack allocated from 00147000 to 00147ff4:\
lowest stack address was 00147c4c
CPU3: stack allocated from 00146000 to 00146ff4:\
lowest stack address was 00146c4c
Note that we used only about 1K of stack, even though in this
case we allocated 4K (and in the main branch, we allocate 32K!)

Right now coreboot's build process produces images that are
not booting on actual hardware because they are smaller than
the actual flash device and also don't have an IFD nor an ME
firmware in them. In order to produce bootable images, you
needed a wrapper script / extra step until now. With this
change, the resulting coreboot.rom is actually bootable.

The currently encoded register constraints fails compilation
for SMM code or any code that compiles with -fPIC. The reason
is that the ebx register is used for GOT base register.
I don't believe the comment eluding to register constraints for AMD
processors still applies. Therefore remove mmio_conf.h, and use the
mmio methods in io.h.

- Adding more and more optional and non-optional parameters
bloated cbfstool and made the code hard to read with a lot
of parsing in the actual cbfs handling functions. This change
switches over to use getopt style options for everything but
command and cbfs file name.
- This allows us to simplify the coreboot Makefiles a bit
- Also, add guards to include files
- Fix some 80+ character lines
- Add more detailed error reporting

across the board.
This change also refactors mrccache.c to limit number of iterations
through the cache area and number of fmap area searches.

If the event log is stored in flash that is not memory
mapped then it must use the SPI controller to read from
the flash device instead of relying on memory accesses.
In addition a new CBMEM ID is added to keep an resident
copy of the ELOG around if needed. The use of CBMEM for
this is guarded by a new CONFIG_ELOG_CBMEM config option.
This CBMEM buffer is created and filled late in the process
when the SMBIOS table is being created because CBMEM is
not functional when ELOG is first initialized.
The downside to using CBMEM is that events added via the
SMI handler at runtime are not reflected in the CBMEM copy
because I don't want to let the SMM handler write to memory
outside the TSEG region.
In reality the only time we add runtime events is at kernel
shutdown so the impact is limited.
Test:
1) Test with CONFIG_ELOG_CBMEM enabled to ensure the event
log is operational and SMBIOS points to address in CBMEM.
The test should involve at least on reboot to ensure that the
kernel is able to write events as well.

- Fix handling of 5-byte Fast Read command in the ICH SPI
driver. This fix is ported from the U-boot driver.
- Allow CONFIG_SPI_FLASH_NO_FAST_READ to be overridden by
defining a name for the bool in Kconfig and removing the
forced select in southbridge config
- Fix use of CONFIG_SPI_FLASH_NO_FAST_READ in SPI drivers
to use #if instead of #ifdef
- Relocate flash functions in SMM so they are usable.
This really only needs to happen for read function pointer
since it uses a global function rather than a static one from
the chip, but it is good to ensure the rest are set up
correctly as well.

The Intel PCH can override the ASPM settings via the MPC2 register.
Add a chip override for F0-F7. Mainboards may implement this as
needed.
This also fixes the final PM setup being done too early. It was
being done prior to the PCIe ASPM setup, which happens in the
bridge scan.

Right now the SPI bus is getting set to 20mhz for transactions
initiated with the software sequence interface.
In order to be able to do reasonable fastread/write/erase we
can bump this up to a higher value at boot before it gets
locked at 20mhz.
To do this read out the speed set in the SPI descriptor for
hardware sequencing and apply it to software sequencing.

At least when CONFIG_CHROMEOS is turned on, it's possible for
CONFIG_FRAMEBUFFER_KEEP_VESA_MODE to be set but for there not to be any valid
information to put into the framebuffer coreboot table. That means that what's
put in there is junk, probably all zeroes from the uninitialized global
variable the mode information is stored in (mode_info).
When a payload uses libpayload and turns on the coreboot framebuffer console,
that console will attempt to scroll at some point and decrease the cursor's y
coordinate until it is less than the number of rows claimed by the console.
The number of rows is computed by taking the vertical resolution of the
framebuffer and dividing it by the height of the font. Because the mode
information was all zeroes, the coreboot table info is all zeroes, and that
means that the number of rows the console claims is zero. You can't get the
unsigned y coordinate of the cursor to be less than zero, so libpayload gets
stuck in an infinite loop.
The solution this change implements is to add a new function,
vbe_mode_info_valid, which simply returns whether or not mode_info has anything
in it. If not, the framebuffer coreboot table is not created, and libpayload
doesn't get stuck.

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
mode (screen resolution, display properties, etc.) in Intel Option
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.

The endianness of an architecture is now set up automatically using Kconfig
and some common code. The available conversion functions were also expanded
to go to or from a particular endianness. Those use the abbreviation le or be
for little or big endian.
Built for Stumpy and saw coreinfo cbfs support work which uses network
byte order. Used the functions which convert to little endian to implement an
AHCI driver. The source arch is also little endian, so they were effectively
(and successfully) inert.

The linux kernel relies on the RTC reporting pending interrupts if
the RTC alarm was used to wake the system. If we clear these flags
here then the rtc-cmos driver in the kernel will think that no
interrupts are pending and will not re-start the timerqueue to
handle the alarm timerqueue node.
This flag doesn't exist in SMM but the rtc code is compiled there.
Since rtc_init() is not called by SMM it is guarded with an ifdef.
I performed several thousand suspend/resume cycles without seeing
an issue where hwclock was unable to read from /dev/rtc. There
still is a potential kernel issue where the timerqueue can stall
but this makes that much less likely to happen on resume.

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.

usb.h directly or indirectly. This change turns that #define from a macro into
a static inline function to move away from the preprocessor, and also renames
