From c6be0d854a99120e0faa224af23e25679790c419 Mon Sep 17 00:00:00 2001 From: Marshall Dawson Date: Sat, 7 Jan 2017 18:17:32 -0500 Subject: amd/pi/hudson: Add alternate method for including amdfw For systems using Chrome OS, place the amdfw outside of cbfs control. The firmware must go to a fixed position at an offset of 0x20000 into the flash device. Potentially improve by adding a warning or error message for the condition when sizeof(amdfw) + sizeof(cbfs and metadata) > sizeof(flash).
