From 5d7ab39024705d872221aab126b42e743674d672 Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Sat, 12 Dec 2015 00:23:15 +0100 Subject: chromeos: import Chrome OS fmaps These are generated from depthcharge's board/*/fmap.dts using the dts-to-fmd.sh script. One special case is google/veyron's chromeos.fmd, which is used for a larger set of boards - no problem since the converted fmd was the same for all of them. Set aside 128K for the bootblock on non-x86 systems (where the COREBOOT region ends up at the beginning of flash). This becomes necessary because we're working without a real cbfs master header (exists for transition only), which carved out the space for the offset.
