drivers/intel/fsp2_0: add option to compress FSP-S in cbfs
Allow the ability for chipset or mainboard to choose to compress FSP-S in cbfs using LZMA or LZ4 routines. To accomplish this fsp_load_component() is added as an assist for performing the necessary logic and allow the caller to provide the destination selection. Since the main cbfs decompression paths are utilized add the appropriate checks for including compression algorithms under the FSP-S compression options. On picasso FSP-S (debug builds) the following savings were measured: no-compression: fsps.bin 327680 none FSP_COMPRESS_FSP_S_LZ4: fsps.bin 98339 LZ4 (327680 decompressed) -70% FSP_COMPRESS_FSP_S_LZMA: fsps.bin 71275 LZMA (327680 decompressed) -78% BUG=b:155322763,b:150746858,b:152909132 Change-Id: I8aa5d8c1cbaf4d08f38a918a9031a2570bc5247e Signed-off-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/41449 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
