From 10b93311ed4e3f70b6b53123d6fd03d3299ba9cb Mon Sep 17 00:00:00 2001 From: V Sowmya Date: Fri, 12 Aug 2022 13:49:45 +0530 Subject: mb/intel/adlnrvp: Skip sending the MBP HOB to save boot time This change is to skip sending the MBP HOB since coreboot doesn't use it and also helps to reduce the boot time by ~40msec on ADL-N. Boot time data: Before: * 955:returning from FspSiliconInit 956,832 (110,268) After: * 955:returning from FspSiliconInit 944,528 (74,213) BUG=b:241850107 TEST=Verified that boot time is reduced by ~40msec and also S0i3 is working.
