ARM: sunxi: Add basic support for Allwinner A80 SoC

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.

With the new naming scheme, I wonder wether it makes sense to have the A80 displayed here and in the machine definition.

I expect anything that falls under sun9i to be compatible, or a trimmed down version. But that's just me.

We know that Allwinner has released the A33, which should be compatible with the A23, sun8i.

And the A83 has been announced, which looks like a trimmed down version of the A80. The next SoC should be arm64, and would not matter here.

Kevin, Shuge, could you provide us with the codenames for the A33 and A83, and what earlier SoC they are based on?

Well, compatible is a rather vague notion. They will be different for sure. Maybe not that different, but still.

We know that Allwinner has released the A33, which should be compatible with the A23, sun8i.

Except that it would not be straight forward for an A33 user for example that he needs to enable the A23 support.

Even though it would be nice to know, it's not really the issue here.

Well, compatible is a rather vague notion. They will be different for sure. Maybe not that different, but still.

So what you're saying is we have a MACH_* Kconfig symbol for each SoC. As we add or test drivers, we mark them as compatible by adding that symbol to the DEPENDS part?

I can live with that.

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

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 don't see any memory nodes in our other DTS.

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.

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).

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?
