From c2240f124578326ebc76466a645c23773eea98eb Mon Sep 17 00:00:00 2001 From: V Sowmya Date: Thu, 4 Aug 2022 22:57:27 +0530 Subject: mb/google/nissa: 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 variants. Boot time data: Before: * 955:returning from FspSiliconInit 1,231,364 (117,051) After: * 955:returning from FspSiliconInit 1,198,221 (79,497) BUG=b:241850107 TEST=Verified that boot time is reduced by ~40msec and also S0i3 is working.
