Built without a ROM image with FSP (u-boot.rom), the U-Boot loader applies the microcode update data block encoded in Device Tree to the bootstrap processor but not passed to the other CPUs when multiprocessing is enabled.
If the bootstrap processor successfully performs a microcode update from Device Tree, use the same data block for the other processors.
