[PATCH 0/4] Add TPM2 support for AMD Versal Gen 2

[Padmarao Begari]

This series adds a TPM2 driver for AMD Versal Gen 2 that exposes the
PLM XilOCP Hardware PCR service as a standard TPM2 interface.

On Versal Gen 2 there is no discrete TPM chip; instead the Platform
Management controller (PLM) provides a set of Hardware PCRs through its
XilOCP module (module ID 13). U-Boot reaches PLM via the TF-A SMC
PASS_THROUGH path using the existing xilinx_pm_request() infrastructure:

 U-Boot -> xilinx_pm_request() -> SMC (PASS_THROUGH) -> TF-A -> IPI -> PLM
