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 uarts on sun9i are still compatible with the dw_8250, but are
located at different addresses.

Like you already found out, the topology code doesn't use the cpu-map
but only relies on the cpu compatible and max frequencies, so you can
drop this.

A comment for this ranges would be nice.
I looks fine otherwise.

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.

Since you changed the memory node in the DTSI, you should probably add
one here too, don't you?

I thought we left fixing that to the bootloader?
I don't see any memory nodes in our other DTS.

Yes, but does the A80 bootloader supports DT and actually fixes it? If
not, then you'll still have to have a memory node, just like on the
A31 (and presumably on the A23).

Not at the moment no. But last I checked none of our board dts files
have separate memory nodes. We only have them in the dtsi, with the
largest supported ram size as its value. Also the bootloader
(u-boot that is) can pass the memory size via atags I think.
At least I'm only getting 512MB RAM on my Optimus, due to u-boot
incorrectly assuming I only have as much. But that's another problem. :(
Would this be a problem when using Android fastboot from the stock
u-boot?
Cheers

We now have initial support for the A80, as well a the datasheet.
Update the documents to reflect this.
