Routine Description:
This routine adds the PPI/Protocol Hobs that are consumed by the DXE Core.
Normally these come from PEI, but since our PEI was 32-bit we need an
alternate source. That is this driver.
This driver does not consume PEI or DXE services and thus updates the
Phit (HOB list) directly
Arguments:
HobStart - Pointer to the beginning of the HOB List from PEI
Returns:
This function should after it has add it's HOBs
