drivers/intel/fsp2_0: add option to compress FSP-M in cbfs
Allow the ability for chipset or mainboard to choose to compress FSP-M in cbfs using LZMA or LZ4 routines. However, only non-XIP platforms will support FSP-M compression. Since the main cbfs decompression paths are utilized add the appropriate checks for including compression algorithms under the FSP-M compression options. On picasso FSP-M (debug builds) the following savings were measured: no-compression: fspm.bin 720896 none FSP_COMPRESS_FSP_M_LZ4: fspm.bin 138379 LZ4 (720896 decompressed) -80% FSP_COMPRESS_FSP_M_LZMA: fspm.bin 98921 LZMA (720896 decompressed) -86% BUG=b:155322763,b:150746858,b:152909132 Change-Id: I5c88510c134b56a36ff1cd97a64b51ab2fea0ab0 Signed-off-by: Aaron Durbin <adurbin@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/41450 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
