From 547a059b34b8bec7b5b441ffd93f2371011f0c47 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Mon, 12 Sep 2016 16:02:33 -0700 Subject: google/gru: Shrink RW_ELOG region to 4KB Since there's currently a limitation in coreboot's code that prevents more than 4KB to be used by the eventlog anyway, this patch shrinks the available RW_ELOG area in the FMAP for Gru down to 4KB. This may prove prudent later if we ever resolve that limitation, so that tools can rely on the area in the FMAP being the same as the area actually used by the read-only firmware code on these boards. BRANCH=gru BUG=chrome-os-partner:55593 TEST=Booted Kevin, confirmed that eventlog got written normally. Ran a reboot loop to exhaust eventlog space, confirmed that the shrink code kicks in as expected before reaching 4KB.
