Note that the firmware volumes in SPI NOR are mapped with different attributes: the FV containing the PEI modules that may execute in place is mapped as uncached memory, given that it requires executable permissions. The FV containing the compressed DXE modules is mapped with device attributes for performance (!), and copied into DRAM by the platform PEIM once permanent memory is installed.
