From 064d6cb8a53b022244082cb2c2ebce2f5fb02486 Mon Sep 17 00:00:00 2001 From: Hung-Te Lin Date: Thu, 17 Oct 2019 12:42:28 +0800 Subject: mb/google: Shrink GBB section size Chrome OS firmware images have moved bitmap resources from GBB into CBFS for a long time, so the GBB should only hold firmware keys and HWID, that is usually less than 10k. ARM boards usually limit GBB to 0x2f00 (see gru, cheza and kukui) but many recent x86 simply copy from old settings and may run out of space when we want to add more resources, for example EC RO software sync. Note, changing the GBB section (inside RO) implies RO update, so this change *must not* be cherry-picked back to old firmware branches if some devices were already shipped.
