342f087249 Google/Snow: Temporary fix for resume failure.
The DDR3 memory initialization (with "mem_reset" set on normal boot) will cause
resume to be unstable, especially when X is running. System may show X screen
for few seconds, then crash randomly and unable to recover - although text
console may still work for a while.  Probably caused by corrupted memory pages.

'mem_reset' (which refers to RESET# in DDR3 spec) should be enabled according
to DDR3 spec. But it seems that on Exynos 5, memory can be initialized without
setting mem_reset for both normal boot and resume - at least no known failure
cases are found yet.  So this can be a temporary workaround.

Verified by booting a Google/Snow device with X Window and ChromeOS, entering
browser session with fancy web pages, closing LID to suspend for 5 seconds, then
re-opening to resume.  Suspend/resume worked as expected.

Also tried the "suspend_stress_test" with X running and finished 100 iterations
of suspend/resume test without failure.

6661350db1 Google/Snow: Enable suspend/resume.
Add the suspend/resume feature into bootblock and romstage.

Note, resuming with X and touchpad driver may be still unstable.

Verified by building and booting successfully on Google/Snow, and then executing
the "suspend_stress_test" in text mode ("stop ui; suspend_stress_test") in
Chromium OS, passed at least 20 iterations.

This function isn't yet used for much, or perhaps anything, but where it
appears in the code it's ored with other values. Since we're not actually
retrieving anything, it might be best to return 0 so that the other values
that are being ored in can be expressed and this function can stay dormant
until it actually has something to do.

Google's Chrome EC can be installed on LPC or I2C bus, using different command

8e88668830 exynos5/snow: remove wait_ms arg from dp_controller_init()
This removes the wait_ms argument from the dp_controller_init(). The
only delay involved is a constant 60ms delay that happens if
everything else goes well. This delay is derived from the LCD spec
so there's no reason it should be baked into the controller code.

(This patch also has the side-effect of fixing a bug where we were
delaying on an undefined value for wait_ms).

5a734168ee Exynos5250: add a microsecond timer
Add a microsecond timer, its declaration, the function to start it,
and its usage.  To start it, one calls timer_start().  From that point
on, one can call timer_us() to find microseconds since the timer was
started.

We show its use in the bootblock. You want it started very early.

Finally, the delay.h change having been (ironically) delayed, we
create time.h and have it hold one declaration, for the timer_us() and
timer_start() prototype.

We feel that these two functions should become the hardware specific
functions, allowing us to finally move udelay() into src/lib where it
belongs.

ad19849c2b Snow: Set up the ChromeOS GPIOs as inputs during the ROM stage.
We need these to be inputs so they can be read when populating the coreboot
tables. It seems like a good idea to do this early to ensure that the input
gate capacitance has had a chance to charge, and if we decide to use
actually use that information during the ROM stage to do earlier RW
firmware selection.

It is not guarded by a ChromeOS config variable because those lines are
always intended to be input GPIOs, regardless of whether we're running
ChromeOS or not.

63516ab8fc exynos5: Re-factor I2C code
This re-factors the Exynos5 I2C code to be simpler and use the
new API, and updates users accordingly.

- i2c_read() and i2c_write() functions updated to take bus number
  as an argument.

- Get rid of the EEPROM_ADDR_OVERFLOW stuff in i2c_read() and
  i2c_write(). If a chip needs special handling we should take care
  of it elsewhere, not in every low-level i2c driver.

- All the confusing bus config functions eliminated. No more
  i2c_set_early_config() or i2c_set_bus() or i2c_get_bus(). All this
  is handled automatically when the caller does a transaction and
  specifies the desired bus number.

- i2c_probe() eliminated. We're not a command-line utility.

- Let the compiler place static variables automatically. We don't need
  any of this fancy manual data placement.

- Remove dead code while we're at it. This stuff was ported early on
  and much of it was left commented out in case we needed it. Some
  also includes nested macros which caused gcc to complain.

- Clean up #includes (no more common.h, woohoo!), replace debug() with
  printk().

602ffd4d75 replace device/i2c.h with simpler version
The existing header was imported along with the Exynos code and left
mostly unchanged. This is the first patch in a series intended to
replace the imported u-boot I2C API with a much simpler and cleaner
interface:

- We only need to expose i2c_read() and i2c_write() in our public API.
  Everything else is board/chip-dependent and should remain hidden
  away.

- i2c_read and i2c_write functions will take bus number as an arg
  and we'll eliminate i2c_get_bus and i2c_set_bus. Those are prone to
  error and end up cluttering the code since the user needs to save
  the old bus number, set the new one, do the read/write, and restore
  the old value (3 added steps to do a simple transaction).

- Stop setting default values for board-specific things like SPD
  and RTC bus numbers (as if we always have an SPD or RTC on I2C).

- Death to all the trivial inline wrappers. And in case there was any
  doubt, we really don't care about the MPC8xx. Though if we did then
  we would not pollute the public API with its idiosyncrasies.

returns value of the static vbe_valid.

void fill_lb_framebuffer(struct lb_framebuffer *framebuffer)
copies the static edid_fb to lb_framebuffer.

There is now a common vbe.h in src/include, removed the two special ones.

In general, graphics in coreboot is a mess, but graphics is always a
mess.  We don't have a clean way to try two different ways to turn on
a device and use the one that works. One battle at a time. Overall,
things are much better.

The best part: this code would also work for ARM, which also uses EDID.

bb31ef906c lynxpoint: Rework LP GPIO handling
This adds some macros for the common GPIO defines and drops
the gpio number definition from each entry.  The end result
is much easier to read.  The wtm2 mainboard gpio list is modified
to use this.

Also fix a bug in the LP version of get_gpio() that was always
returning zero due to a miscompare.

0d4a0f2c69 fox_wtm2: First step support for coreboot-based graphics startup
This code is the initial version of FUI for haswell and wtm2.

The code is simplified from before in many ways. I've gotten rid of
the opcode table, because it obscured meaning and I don't think it is
needed any more. Register sets, mainly used for reset, are just lines
of code -- not many of them. There are a bunch of not-yet-documented
registers here; the VBIOS seemed to think they were necessary and
testing shows they seem to be right.

As a bit of added paranoia, we always include the VBIOS code as our
emergency recovery path. You have to run it now anyways, so this is no
regression from our current situation; and, if all goes well, in a
week (or so), you'll never have to run it again, but like the Force
and nose hair, it will be with you always.

The code can return in three ways. The first, best way is success:
panel is up and the VBIOS need not run. The second mode is that we
tried to light up the panel but could not, for some reason, but will
return with the panel partly up. In this case, it's ok not to power
cycle the panel. The third, worst case, which will NEVER happen, ha
ha, is that we have to turn the panel off and wait the required 600ms
for it to cycle. Life sucks sometimes. This failure mode is in the
'hang on we're going to fix it' category now that we have ramstage in
RW.

The Big Goal here is to create something other coreboot ports can use
as well. The guys doing the x60 report that the link FUI works,
without too many mods, on that chipset, so it seems Intel is keeping
things from changing too much over time.

Also, again, please note: this and the next 3 versions will ALWAYS fail.
The goal is to verify the correctness of the recovery path.

The bizarre tab-space formatting in drm_dp_helper.h is from the original,
as in i915_reg.h

BUG=None
TEST=build and boot wtm2 and see that FUI failed in a way that VBIOS can
recover from

bde97c09ad haswell: configure c-states
The c-states are configured according to the BWG, however the
package c-states are disabled as they currently cause platform
instability. The exposed ACPI c-state to processor c-state mapping
are as follows for ULT boards:
	ACPI(C1) = MWAIT(C1E)
	ACPI(C2) = MWAIT(C7S long latency)
	ACPI(C3) = MWAIT(C10)
The non-ULT boards have an expoed c-state mapping:
	ACPI(C1) = MWAIT(C1E)
	ACPI(C2) = MWAIT(C3)
	ACPI(C3) = MWAIT(C7S)

Included in this patch is removing the updating of current limit
registers as some of the MSRs are different and the proper values
are currently unknown. Lastly, some of the MSRs were renamed to
match the BWG.

The current cbmem region is renamed to ACPI_GNVS_PTR to

not actually contain the GNVS.
