drivers/intel/fsp2_0: Add preload_fspm and preload_fsps
In the non-XIP world, FSP is normally memmapped and then decompressed. The AMD SPI DMA controller can actually read faster than mmap. So by reading the contents into a buffer and then decompressing we reduce boot time. BUG=b:179699789 TEST=Boot guybrush and see 30ms reduction in boot time Signed-off-by: Raul E Rangel <rrangel@chromium.org> Change-Id: I28d7530ae9e50f743e3d6c86a5a29b1fa85cacb6 Reviewed-on: https://review.coreboot.org/c/coreboot/+/58987 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org>
