Hello, This series updates the existing PHB4 model to the latest spec: "Power Systems Host Bridge 5 (PHB5) Functional Specification Version 0.5_00".
Updates include the following: - implemented sticky reset logic - implemented read-only, write-only, W1C and WxC logic - return all 1's on read to unimplemented registers - update PCIE registers for link status, speed and width - implement IODA PCT debug table without any functionality - set write-mask bits for PCIE Link-Control-2 register that is read/written by PHB4 - update LSI Source-ID register based on small/big PHB number of interrupts Also, a new testbench for PHB4 model is added that does XSCOM read/writes to various registers of interest and verifies the values.
