From 6a342360da6f8523fbbbb938cd11327d81d70ebe Mon Sep 17 00:00:00 2001 From: Wonkyu Kim Date: Thu, 13 Oct 2022 13:40:37 -0700 Subject: mb/google/rex: 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 ~40 ms. Boot time data Before: * 955:returning from FspSiliconInit 1,656,985 (274,416) After: * 955:returning from FspSiliconInit 1,593,036 (233,286) BUG=b:252410202 TEST=Verified that boot time is reduced by ~40 msec.
