In the single GPU configuration, the T420 has an LVDS port, one DP++
and one VGA port connected to the IGD. Docking solutions feature up to
two additional DP/DVI-D ports, also directly connected to the IGD.
This makes the list of ports to probe pretty long (takes about 70ms
if nothing but LVDS is connected). We could save about 20~30ms if we'd
limit the ports in case we are not docked or have a discrete GPU.

This reuses some of gm45 code to set up the panel.
Panel start and stop delays and pwm frequency can now be set in
devicetree.
Linux does not make the difference between 945gm and gm45
for panel delays, so it is safe to assume the semantics of those
registers are the same.
The core display clock is computed according to "Mobile Intel® 945
Express Chipset Family" Datasheet.
This selects Legacy backlight mode since most targets have some smm
code that rely on this.
This sets the same backlight frequency as vendor bios on Thinkpad X60
and T60.
A default of 180Hz is selected for the PWM frequency if it is not
defined in the devicetree, this might be annoying for displays that
are LED backlit, but is a safe value for CCFL backlit displays.

As SPI master by default decodes all of top 16MiB below
4GiB, initial cache-as-ram line fills may have actually
read from SPI flash even in the case DCACHE_RAM_BASE was
below the nominal 4GiB - ROM_SIZE.
There are no reasons to have this as board-specific setting.

USB AO is the internal name for the dedicated charging port on
ThinkPads when in S3 or lower.
AOEN (bit 0) is internal name for enabling this feature while AOCF
(bits 2 and 3) is the configuration field. According to Peter Stuge,
AOCF can be configured in this way:
00 => AC S3 S4 S4 USB on, battery S3 USB on, battery S4 S5 off
11 => AC S3 S4 S4 USB on, battery S3 S4 S5 USB off
10, 01 => equivalent to 00
This commit also adds a new configuration field in the CMOS of the
X220 and the X201 to activate this feature. It probably can be also
added to all the ThinkPads that support this functionality.
With this functionality USB devices are able to negotiate full power
from the dedicated port (usually the yellow one) even in S3.
Tested on a X201 and X220 with an Android smartphone: with this
feature enabled it shows "Charging" when connected during S3, without
it it shows "Charging slowly" (or it doesn't charge at all on the
X201).
For some reasons the "AC only" mode doesn't work, so it has been

Those registers are only used on more recent Intel platforms featuring a
PCH. The DP registers on G4X hardware are at a different offset.

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.

The datasheets on gm45: "Mobile Intel® 4 Series Express Chipset Family"
mention the possibility of having 352M ram preallocated for the
integrated graphic device. This only worked fine if the amount of ram in
the system was 3GB or less. When 4G or more is installed, memory is
remapped to create a 1GB large pci mmio hole which is not enough and
creates conflicts when 352M vram is used.
This patch increases the pci mmio hole size on Lenovo x200 to allow
352M vram to work.
TEST: build and flash on target with 4GB ram or more, use nvramtool to
set gfx_uma_size to 352M and reboot.
