The Allwinner A80 is a new Cortex octo-core A7/A15 big.LITTLE SoC.
While it's processor cores and interconnecting bus are new, it
re-uses many peripherals found in earlier Allwinner SoCs.

The A80 Optimus Board is was launched with the Allwinner A80 SoC.
It was jointly developed by Allwinner and Merrii.
This board has a UART port, a JTAG connector, USB host ports, a USB
3.0 OTG connector, an HDMI output, a micro SD slot, 8G NAND flash,
4G DRAM, a camera sensor interface, a WiFi/BT combo chip, a headphone
jack, IR receiver, and additional GPIO headers.
This patch adds only basic support.

With this patch set on top of Maxime's sunxi-next branch, I get as far
as searching for the rootfs.
CPUs 1-7 fail to boot with -38, which I guess is due to the vendor
U-Boot not yet supporting PSCI.
Thanks a lot for your work and help, Chen-Yu!
Regards,
Andreas

That, and Linux not having some SMP bringup code either.
