vendorcode/intel/fsp/fsp2_0/cpx_sp: Update to FSP ww24 release and adapt soc
The previous Intel CPX-SP FSP release was ww20 release. The ww22 release fixs issues related to FSP_NV_STORAGE HOB. The end of end flow of using memory training data to generate FSP_NV_STORAGE HOB and using memory training data passed from bootloader to skip memory training, works now. This saves 8 minutes of boot time (with FSP verbose logging enabled on DeltaLake server). This release also adds UPD parameters to support IIO bifuration. The ww24 release has following updates: a. Removed a number of unnecessary UPD parameters, such as mmiolSize, mmiolBase, OemHookPostTopologyDiscovery, OemGetResourceMapUpdate. b. Added UPD parameters to support PCIe ports configuration. c. Updated IIO_UNIVERSAL_DATA HOB, each stack now has mmio base/limit fields, in addition to PCIe resource memory base/limit fields. With ww24 release, the issue with PCIe link training persists. On YV3 config A, the onboard NIC card has x4 connection to port 2D. This NIC device is not recognized by FSP. Corresponding soc/intel/xeon_sp/cpx change is made: * There are changes in PLATFORM_DATA structure, so hob_display.c is updated. * There are changes in UPD parameters, so romstage.c is updated.
