Requesting low power acpi cpu c-states has two software interfaces:
Using P_LVLx I/O reads or using equivalent MWAIT requests.
This change makes it more consistent with newer targets that use MWAIT
requests.
There also exists extended intel acpi c-states which can be enabled
in two ways:
- using a substate hint to the mwait request (defined in bios);
- setting a model specific register (msr)
Currently this is done by setting the right msr bits but with this
change one can experiment by adding substate hints.

An epic battle to fix Nehalem finally ended when we found an odd mask
set in SMRR. This was caused by a wrong calculation of TSEG size. It
was assumed that TSEG spans the whole space between TSEG base
and GTT. This is wrong as TSEG base might have been aligned down.
TEST: On X201, copied 1GiB from usb key to sd-card and verified.

This patch implements native resolution, VESA mode, on the VGA output of
x4x.
It relies on EDID to modeset, but has a fallback-mode (640 x 480 @
60Hz) if this is no EDID could be found. This fallback mode only works
in textmode since in VESA mode some payloads (grub2) rely on VBE info,
which is being generated from an EDID.

The datasheets "Intel® Core™ Duo Processor and Intel® Core™ Solo
Processor on 65 nm Process" mentions cpu C-states substates which can
either be attained by adding a substate hint to the MWAIT/P_LVLx request
or automatically by setting some msr bits correctly.
This just sets the same msr bits as model_6fx to enable
dynamic L2 cache, C2E and C4E acpi cpu states.
The result is that when limiting a thinkpad x60 with a yonah T2400
cpu to the acpi cpu C2 state, the idle power usage drops from 18W to
14W. When the lowest C-state is set to C4 the idle power usage seems
to remain similar.

We found that Kevin board PHY0 and PHY1 eye-diagram margin
is not enough to make compliance test pass, and the PHY0 USB
SI is worse than PHY1, because of the higher PCB impedance.
For PHY0, we can't improve the eye-diagram by SW PHY tuning,
so we need to reduce the RBIAS resistance from 133 ohm to 115
ohm, it can help to increase the eye-height.
For PHY1, we can improve the eye-diagram by setting the max
pre-emphasis level.
And after the above change, the USB2 signal amplitude will
become larger at the test point near to SOC USB2 PHY, in order
to avoid mis-trigger the disconnect detection (650mV), we need
to disable pre-emphasize in eop state.

Instead of hard-coding the polarity of the GPIO to active high/low,
accept it as a parameter in devicetree. This polarity can then be used
while calling into acpi_dp_add_gpio to determine the active low status
correctly.
BUG=chrome-os-partner:55988
BRANCH=None
TEST=Verified that correct polarity is set for reset-gpio on reef.

Only acpi_dp of type DP_TYPE_TABLE is allowed to be an array. This
DP_TYPE_TABLE does not have a value which is written. Thus,
acpi_dp_write_array needs to start counting from the next element type
in the array. Fix this by updating the initialization in for loop for
writing array elements.
BUG=chrome-os-partner:55988
BRANCH=None
TEST=Verified that the correct number of elements are passed for
add_gpio in maxim sdmode-gpio.

Some Chrome OS ECs require a small amount of time after a SPI
transaction to reset their controllers before they can service the next
CS assertion. The kernel and depthcharge have always enforced a 200us
minimum delay for this... coreboot should've done the same.

TEST=Booted Kevin in recovery mode, confirmed that recovery events got
logged with correct timestamps in eventlog.

GPIO1_B3 (WLAN_MODULE_RST#) defaults as a pull-up input, but it is also
"pulled up" by 1.8V_WLAN. However, 1.8V_WLAN remains low for some time
during early boot. This leaves the signal floating somewhere in the
middle.
This has two potential issues:
(1) we're leaking some power for some (hopefully) short period of time
(2) we are possibly screwing with the Wifi power sequence; we aren't
supposed to deassert PDn (i.e., MODULE_RST#) until all the rails
have fully ramped for some period of time
Neither of the above issues are likely to be significant, but it is nice
to fix, I expect.
