The management engine is slow, requiring at least 500ms between
when the Dram Init Done message is sent (right after memory training)
to when the MBP will report that it is successfully cleared and
that the ME can finally be sent the EOP message.
Currently this is adding 100-150ms to the boot time. If we defer
waiting for the MBP Clear indicator until the finalize step we
can gain back that lost time.

There are specific programming requirements for the usb3 ports
on all LynxPoint chipsets when transitioning to D0 or D3.
LynxPoint-LP has additional workaround steps needed involving

The options that keep track of whether there are arch versions of the standard
string functions shouldn't be in the arch/x86 directory since they apply to
all architectures. Move them into the higher level, shared Kconfig defaulting
to off. Then, in each applicable arch (currently all of them) they can be
selected to on.
BUG=None
TEST=Built and booted on Link and Snow.

Some kernel assembly code uses a W macro to optionally add a .w to
instructions that need to be 32 bit thumb. The gnu assembler doesn't seem to
need the .w and won't assemble if it's provided.
BUG=None
TEST=Built for snow with the kernel's implementation of memmove (which uses
W()), and used memmove successfully when loading from CBFS.

RAM_ID0 was used as the table MSB, and RAM_ID2 as the LSB. This is the
opposite of expected. Reverse these two GPIOS to make current boards
work. For future boards, we will change the signal names on the
schematic to be consistent.
TEST=Manual. Build image, verify Hynix board loads correct SPD.

The display port bridge on pit is different from the one on snow and needs to
be initialized differently. Instead of waiting for the chip to come up on its
own and assert the hotplug detect, we need to access it over i2c and get it up
and running ourselves.

TEST=Built and booted into depthcharge on pit and saw that the video
initialization code in coreboot worked better, successfully training the link
but then failing elsewhere later on.

This driver is basically the same as the one in U-Boot but without the device
tree stuff. That driver is, in turn, a straightforward implementation of the
sequence of register writes described in the data sheet. Comments were added
in U-Boot which helpfully describe what the register writes are actually
doing and are kept.

TEST=Built and booted into depthcharge on pit and verified that after the
bridge was initialized, the link was initialized successfully.

Data is intended to be a byte array, so it should be described by a type which
has a fixed size equal to an 8 bit byte. Also, the data passed to write
shouldn't be modified and can be const.
