I'd like you to reexamine a change. Please visit

to look at the new patch set (#5).
Change subject: intel/alderlake: Remove FSP_PUBLISH_MBP_HOB config for RPL ......................................................................
intel/alderlake: Remove FSP_PUBLISH_MBP_HOB config for RPL
Currently, the RPL FSP retrieves the chipset initialization version via HECI commands due to the MBP HOB creation being disabled (SkipMbpHob=1).This method has resulted in an approximate 150ms increase in boot time.Investigations are ongoing to determine the cause of the delay when using HECI commands.As an interim solution, this patch sets SkipMbpHob=0, enabling the use of MBP HOB or acquiring the chipset initialization version, which is expected to reduce the boot time.
BUG=b:328430167 TEST= Able to build,boot and collect boot time data of brya.
With this patch: 963:returning from FspMultiPhaseSiInit 1,337,481 (249,046)
Without this patch: 963:returning from FspMultiPhaseSiInit 1,496,268 (408,194)
