Implement shared display support.
This change fills up the stubs in lib/vbexport/display.c to
provide support on both ARM (where LCD driver is used) and
X86 (where the CFB driver is used) platforms.
BUG=chrome-os-partner:4552
TEST=manual
On X86 (alex with a Dediprog programmer connected to it), run the
following commands:
. emerge-x86-alex vboot_reference-firmware chromeos-u-boot chromeos-coreboot
dd if=/build/x86-alex/coreboot/coreboot.rom of=/tmp/coreboot seek=3584 bs=1K
sudo flashrom -p dediprog -w /tmp/coreboot
. Reboot the machine, observe it come up to boot> prompt, start
ChromeOS (using the `boot' cli command).
On ARM (tegra2_kaen)
. emerge-tegra2_kaen vboot_reference-firmware chromeos-u-boot chromeos-bootimage
. program the resulting image into Kaen, restart it, observe the
machine come up.
. install the new OS image on the machine, restart it, observe
the machine come up.
. request recovery reboot using crossystem, restart the machine,
observe it come up in recovery request mode.
This test case actually failed: the system did show the
recovery request screen, but then proceeded to boot from the
plugged in USB stick (it was supposed to wait for the stick to
be removed/reinserted)
