coreboot passes information about the serial port implementation to
payloads through a cbtables entry.
We set the register width to 1 on most SoCs because that looked as good
a default as any, but checking the uart structs they use, it's 4 for all
of them.

Some vendors store lower frequency profiles in the regular SPD,
if the SPD contains a XMP profile. To make use of the board's and DIMM's
maximum supported DRAM frequency, try to parse the XMP profile and
use it instead.
Validate the XMP profile to make sure that the installed DIMM count
per channel is supported and the requested voltage is supported.
To reduce complexity only XMP Profile 1 is read.
Allows my DRAM to run at 800Mhz instead of 666Mhz as encoded in the
default SPD.

If we only need to "combo" two PSP directories into one image,
we can put first address in romsig 0x10 and second one in
romsig 0x14.
If we really need to put three, the 0x14 is the combo directory
which points to multiple level-2 PSP directories.
I guess that two PSP can also use combo directory, with only
one level-2 directory. But nobody seems to do that.

When CONFIG_LP_TIMER_RDTSC is enabled honor the TSC information
exported in the coreboot tables as the cpu_khz frequency. That
allows get_cpu_speed() not to be called which currently relies
on the 8254 PIT. As certain x86 platforms allow that device
to be optional or turned off for power saving reasons, allow
a path where get_cpu_speed() is no longer called. Additionally,
this approach also allows the libpayload to not duplicate logic

Issue observed:
The PCIe Root port shows up in GNU/Linux but no PCIe device
is being detected.
Test system:
* Gigabyte GA-B75M-D3H (Intel Pentium CPU G2130)
* Lenovo T530 (Intel Core i5-3320M CPU)
Problem description:
The PEG Root port link training on Ivy Bridge needs to be manually started.
Problem solution:
The bits are set in early_init to meet PCIe reset timeout of 100msec.
The bits should be set in PCI device enable function, but this causes the
PCI enumeration to not detect the card, as it's still booting. Adding
a fixed delay of 100msec resolves this problem, but this would
increase boot time.
Read the PCI base revision mask to make sure it's any IvyBridge CPU.
Don't run the code on MRC path as it has its own PEG initilization code.
Tested with:
* Nvidia NVS 5400M (PCIe2)
* ATI Radeon HD4780 (PCIe2)
* Nvidia GeForce 8600 GT (PCIe1)
Untested:
* PCIe3 devices
Final test results:
The PEG device shows up under GNU/Linux and can be used without issues.
