From 27af8da7cb49a2c81e50ab5df4b92cb53cf5d41e Mon Sep 17 00:00:00 2001 From: Benjamin Doron Date: Fri, 26 Feb 2021 04:36:05 +0000 Subject: [PATCH] soc/intel/skylake: Enable compression on FSP-S Use LZ4 algorithm to compress FSP-S. This saves ~40 KiB and reduces the boot time by ~7 ms. LZMA would save a further ~1 KiB, but adds ~9 ms to the boot time.
