Stefan Reinauer a42e2f4daa Add spinlock to serialize Intel microcode updates
Updating microcode on several threads in a core at once
can be harmful. Hence add a spinlock to make sure that
does not happen.

Bill Richardson 0a405bafc5 cros: Inform U-Boot via fake gpio when VGA Option ROM is loaded
This prepares the way for vboot to inform coreboot when it needs the VGA
Option ROM loaded. Coreboot can't always know when it's needed (with
keyboard-based dev-mode, coreboot can't tell if we're in dev-mode or not).
By the time we get to U-Boot, it's too late, so we need two extra bits - one
for vboot to tell coreboot to load the Option ROM and another for coreboot
to let vboot know it's been done.

This change sets up the communication, but doesn't act on it just yet.

Even with this CL we always load the VGA Option ROM, so there's nothing to
test. There should be no user-visible change.

Vadim Bendebury 6b3d09e787 Export optionrom status on Stumpy/Lumpy
ChromeOS' top of the tree u-boot expects coreboot to export information
about option ROM status (started/not started). Stumpy and Lumpy were
left behind and are not exporting this information. This CL fixes the
problem.

Stefan Reinauer 75dbc389ec Clean up stack checking code
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

Stefan Reinauer 4221a19574 Add method for delaying adding of timestamps
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

Ronald G. Minnich 8b93059ecc Pass the CPU index as a parameter to startup.
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.

Ronald G. Minnich 000bf83c93 Support better tracking of AP stack usage.
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!)

Duncan Laurie 215f278563 ELOG: Support for non-memory mapped flash
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.

Duncan Laurie 23b0053586 SPI: Fix and enable Fast Read support
- 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.

Gabe Black fb8632ab58 oprom: Ensure that mode information is valid before putting it in the tables.
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.

Vadim Bendebury 6d18fd09c3 Utility to dump boot timing table
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)

that device as a console. This change adds a config option which skips the
call to console_init in start_main.

Gabe Black d94512edee libpayload: Add CB_ prefixes to some constants in coreboot_tables.h.
This makes their names more consistent with other constants in this header,
avoids name collisions, and makes it more obvious where the names came from.

Gabe Black 025667f0ec libpayload: Change "GPIOs" into flags.
Some constants which were used to interpret the contents of the coreboot
tables were moved to the appropriate libpayload header file. The constant which
describes the maximum length of a GPIO name was renamed to have a CB_ prefix.
That makes it more obvious what sort of GPIO name it describes, and reduces the
change of a name collision. It also makes it more consistent with other names
in that header, although some other exceptions still exist.
