mb/ocp/monolake: use RW_VPD to configure FSP UPD
Summary:
This patch adds:
* A framework to use VPD binary blob 2.0 data to configure
FSP UPD.
* A library to configure HyperThreading FSP UPD variable.
The framework is added in romstage to customize FSP UPD settings.
If RW_VPD and binary blob are not found, or if there is no
"HyperThreading" setting in the binary blob, original
configuration is used.
Test Plan:
* Build an OCP MonoLake coreboot image, run following command
to initialize RW_VPD and insert HyperThreading key:
vpd -f build/coreboot.rom -O -i RW_VPD -s 'HyperThreading=0'
* Flash the image to MonoLake, boot and observe following
message in boot log:
Detected 16 CPU threads
If RW_VPD partition does not exist, or if HyperThreading
key/value pair does not exist, the boot log has:
Detected 32 CPU threads
