2018-06-11inteltool: Add dumping of full PCR portsYouness Alaoui
SoCs from Skylake on have many settings as so called private con- figuration registers (PCRs). These are organized as 256 ports with a 64KiB space each. We use the Primary to Sideband (P2SB) bridge's BAR to access them.

2018-01-15inteltool: Support for nasty Primary to Sideband Bridge (P2SB)Nico Huber
The Primary to Sideband Bridge (P2SB) is the interface to Private Con- figuration Registers (PCR) including GPIO configuration. Of course, access is restricted to Intel partners and criminals, so the PCI device is hidden from the OS. Probably we only need to fetch the SBREG_BAR address and can hide the PCI device again after that.
