4bddb75c4e chromeos: always enable timestamps
Timestamps should not be forced on by a subset of chipsets.
However, they are a requirement on Chrome OS platforms, so
have CONFIG_CHROMEOS select it.

0e90dae584 Move TPM code out of chromeos
This code is not specific to ChromeOS and is useful outside of it.
Like with small modifications it can be used to disable TPM altogether.

b890a1228d Remove address from GPLv2 headers
As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.

However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.

util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

2eaa0d49e1 intel: Correct MMIO related ACPI table settings
Several of the intel platforms define the region reserved
for PCI memory resources in a location where it overlaps
with the MMIO (MCFG) region.

Using the memory map from mohon_peak as an example:

  0. 0000000000000000-0000000000000fff: CONFIGURATION TABLES
  1. 0000000000001000-000000000009ffff: RAM
  2. 00000000000a0000-00000000000fffff: RESERVED
  3. 0000000000100000-000000007fbcffff: RAM
  4. 000000007fbd0000-000000007fbfffff: CONFIGURATION TABLES
  5. 000000007fc00000-000000007fdfffff: RESERVED
  6. 00000000e0000000-00000000efffffff: RESERVED
  7. 00000000fee00000-00000000fee00fff: RESERVED
  8. 0000000100000000-000000017fffffff: RAM

  The ACPI table describing the space set aside for PCI memory
  (not to be confused with the MMIO config space) is defined
  as the region from BMBOUND (the top of DRAM below 4GB) to
  a hardcoded value of 0xfebfffff. That region would overlap
  the MMIO region at 0xe0000000-0xefffffff. For rangeley
  the upper bound of the PCI memory space should be set
  to 0xe0000000 - 1.

  The MCFG regions for several of the affected chipsets are:
  rangeley    0xe0000000-0xefffffff
  baytrail    0xe0000000-0xefffffff
  haswell     0xf0000000-0xf3ffffff
  sandybridge 0xf8000000-0xfbffffff

TEST = intel/mohonpeak and intel/bayleybay.

aae53ab76a kbuild: automatically include SOCs
This change switches all SOC vendors and southbridges
to be autoincluded by Makefile.inc, rather than having to be
mentioned explicitly in soc/Makefile.inc or in
soc/<vendor>/Makefile.inc.

This means, vendor and SOC directories are now "drop
in", e.g. be placed in the coreboot directory hierarchy
without having to modify any higher level coreboot files.

The long term plan is to enable out of tree components to be
built with a given coreboot version (given that the API did not
change).

df4081e72c broadwell: Clear USB3.0 PORTSC status bits in sleep_prepare.
Found that any non-USB3.0 devices connected to type-C ports
(displayPort dongles) cause XHCI port to see connection which in turn
leads us to enter USB compliance mode.

That in turn causes the port to wake the system for a yet-to-be
determined reason.  Clearing the PORTSC status bits (actually just
CSC) seems to remedy the wake.

ab1e96a099 broadwell: Fixes for _SWS support
- These should be 64bit values so when they try to return -1
it is interpreted properly by the kernel.
- The GPE value needs to be reset at the start so it does not
return stale data from a previous resume.
- If a GPE register is zero the value should only be updated
if it has not yet found a set bit.

c99681f4f2 broadwell: Clean up ME device and add new ME10 flow
In order to avoid a 300ms timeout waiting for mbp_cleared flag
to be set there is a new flow for the ME10 1.5MB firwmare that
we can follow which will save significant boot time.

This requires sending new commands that do not generate an ACK
message, and ensuring an HMRFPO LOCK message is sent.

In addition now that the delay is removed clean up the ME path
to do the work in init() step and add a final() step that does
the disabling of the PCI device.

bf5a4bbac5 broadwell: Correct XHCI offset for USB 3.0 ports
Looks like Intel has added two more USB 2.0 ports from LynxPoint to
Broadwell, which shifted the port offsets of the USB 3.0 ports behind
them. The USB 2.0 ports are now 0x480 to 0x520 and the 3.0 ones 0x530 to
0x560 (at least according to what my kernel seems to think). The offset
of the first USB 3.0 port is hardcoded and seems to have been copied
over without accounting for this, meaning when we try to operate on all
USB 3.0 ports we actually operate on the last two 2.0 and the first two
3.0 ports instead.

This patch should fix the bug for now. In the future, we might want to
consider dynamically detecting port locations through the Protocol
Capability structures at the end of the XHCI register set instead.

1164d51828 broadwell: Increase I2C SDA hold timing to 300ns
I2C bus SDA hold time can be marginal with 60ns value, especially
when there is level shifter on the bus. So program it to 300ns
based on Fast-mode specification, which is between 0 to 900ns.
Apply the same timing for Standard-mode as well.

Refer to original bug on BayTrail chrome-os-partner:28092, this
is to carry forward the fix to Broadwell.

aec2442f3c broadwell: add RCBA posting read after writing
MEI PCI device has internal logic to flush out the posted writes
before returning completion for non-posted request. When doing a RCBA
write to function disable and then using the PCI CFG RD cycle, need
to do RCBA posting read after writing to it to make sure the write
went through.

As Aaron sugegsted, abstracted function disable path to a common
function.
