Tested on X230 with an external screen connected to every one of the
DP ports (miniDP on mainboard, two DP ports on dock), the GRUB payload
can display on both the external screen and the internal LVDS screen.
This is a copy-paste of I8e02c8003ff745d05ee272c59377174847f5219c.

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.

Commit bf264e94 (i945:) adds a PCI reset to the romstage, and commit
bc8613ec (Fix i945 based boards) fixes that to use the correct
delay of 200 ms. This code was then copied over, when adding support for
the Lenovo T60.
The reset was related to the shipped crypto card on the Roda RK886EX and
Kontron 986LCD-M, so is not needed on the Lenovo T60. So remove it, to
reduce the boot time by 200 ms.
The same change is done for the Lenovo X60 in commit 7676730b
(mb/lenovo/x60: Remove PCI reset code from romstage).

We define AGESA_LEGACY as an implementation of mainboard
that has its romstage main completely under mainboard/
directory. We have learnt from other platforms this approach
has several downsides when it comes to making platform-wide
improvements.
We start by creating per-family romstage.c file, which
boards will gradually take into use by removing the
AGESA_LEGACY Kconfig option we here apply to all of them.

- Change preprocessor #if to standard C if. This will get optimized
out if the config option is disabled, but lets the compiler check the
contents.
- CONFIG_USBDEBUG is always going to be defined even if it's disabled,
so this check is not going to work as expected.
See the coreboot Kconfig documentation in /Documentation/core/Kconfig.md

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.

Currently, the USB ports are still powered during S3, so turning
them off may reduce the power consumption.
Note that, when the USB Always on feature is enabled, the USB
ports are always powered, regardless of the USBP state.
This patch also disables the audio, as it might consume some
power or generate some noise.
Both the USB power and the audio are reenabled by coreboot during

- SeaBIOS payload
- Booting into Linux 4.9.6 with Debian/unstable installed on the
internal HDD/SDD slot
- Native raminit
- Both native VGA init and option rom VGA init

- Battery status readout
- Basic ACPI functions (power button event; power-off; reboot)
- thinkpad-acpi hotkey functions
- thinkpad-acpi LED control (red thinkpad LED)
- Suspend to RAM and resume works
- Mini displayport output works
Known issues:
- Patches needed for EC battery support
https://review.coreboot.org/#/c/18348/

- No thermal zone since temperature sensing is not H8-compatible

Add support for Lenovo Thinkpad L520.
The files are generated by autoport,
and are successfully tested on the board.
L520 has got 4MiB flash chip, that contains a "slim" ME
with 1.2MiB only. The flash IC has to be desoldered, as
it won't be accessible in circuit. It is located on top
of the mainboard right under the touchpad.
Test-setup:
Extract the following blobs from vendor BIOS:
* Intel Flash Descriptor
* Intel Management Engine
* Intel VBios
The laptop has been externaly flashed. It was able to
turn on the display and load SeaBIOS.
Latest debian has been booted from harddisk.
Latest fedora has been booted from USB flash drive.
The following hardware has been tested and is working:
* Display using Option Rom
* PCIe wifi
* Ethernet
* Keyboard, trackpoint and touchpad
* Some Fn functions keys
* Volume Keys (except mic mute)
* Status LEDs
* Audio (headphone jack only)
* USB ports
* Native raminit dual channel (2 DDR3-1333 DIMMs tested)
* SATA cdrom
* SATA harddrive
Broken:
* Some Fn functions keys
* Microphone mute button
* Speakers (but headphone jack gives sound)
Untested:
* Expansion slot
* SD card slot
* Docking station
* Native gfx init
The EHCI debug port is the first one on the right side.

Having same memory region set as both WRPROT and WRBACK
using MTRRs is undefined behaviour. This could happen if
we allow DCACHE_RAM_BASE to be located within CBFS in SPI
flash memory and XIP romstage is at the same location.
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.

pci_read/write calls before PCI MMCONF is enabled via MSR.
This happens early in romstage amd_initmmio() for all cores.

When MRC cache is available, first read only the SPD unique
identifier bytes required to detect possible DIMM replacement.
As this is 11 vs 256 bytes with slow SMBus operations, we save
about 70ms for every installed DIMM on normal boot path.
In the DIMM replacement case this adds some 10ms per installed DIMM
as some SPD gets read twice, but we are on slow RAM training boot path
anyways.

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
disabled.

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.
