Include IPQ8064 SBLs code in the coreboot bootblock
We want the coreboot build produce an image which can be run on the
target, even if the remaining parts of the bootprom (recovery path,
read-write stages, gbb, etc.) are not available yet.
This is achieved by including the Qualcomm SBLs blob in the bootblock.
CQ-DEPEND=CL:193518
BRANCH=None
BUG=chrome-os-partner:27784
TEST=manual
. run the following commands inside chroot to confirm expected image
layout (no actual code is executed on the target yet):
$ emerge-storm coreboot
$ \od -Ax -t x1 -v /build/storm/firmware/coreboot.rom 2>/dev/null | head -1
