Certain platforms have a poorly performing SPI prefetcher so even if
accessing MMIO BIOS once the fetch time can be impacted. Payload
loading is one example where it can be impacted. Therefore, add the
ability for a platform to reconfigure the currently running CPU's
variable MTRR settings for the duration of coreboot's execution.
The function mtrr_use_temp_range() is added which uses the previous
MTRR solution as a basis along with a new range and type to use.
A new solution is calculated with the updated settings and the
original solution is put back prior to exiting coreboot into the OS
or payload.
Using this patch on apollolake reduced depthcharge payload loading
by 75 ms.

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

after the build has completed, as can be done with everything that

Almost all boards and chipsets within the codebase assume or
use SPI flash as the boot device. Therefore, provide an option
for the boards/chipsets which don't currently support SPI flash
as the boot device. The default is to assume SPI flash is the
boot device unless otherwise instructed. This falls in line
with the current assumptions, but it also allows one to
differentiate a platform desiring SPI flash support while it not
being the actual boot device.
One thing to note is that while google/daisy does boot with SPI
flash part no SPI API interfaces were ever implemented. Therefore,
mark that board as not having a SPI boot device.

Since the socket layer is implemented with this CPU model, there
could potentially be multiple CPU models included. There can be
only one cache_as_ram include, so select it directly within
the socket directory.

Zero-filling memory below 1 MiB resets car_migrated variable so
any CAR GLOBALs are not addressed correctly for the remaining
time in romstage. Also there is no actual need to do this as
ramstage loader handles BSS.
This fixes regression with commit 70cd54310 that broke fam10 boards
with romstage spinlocks enabled.
