[9front] 9front on the Allwinner A64

[sirjofri <sirjofri+ml-9front@sirjofri.de>]

Hello,

adventuresin9 recently mentioned the A64 in the last video[1]. There are quite a few people interested in getting a 9front system on A64 powered devices (e.g. the pinephone).

Here's my attempt at porting 9front to that platform[2]. It's in the early stages and only a few things work.

To be precise, I can only boot the program (I wouldn't call it "kernel" yet) using uboot and output stuff to the serial console. I tried setting up a proper memory map, but when activating it I can't get the mapped hardware addresses for the serial connection working.

The linked source directory is meant to be placed as a full directory to /sys/src/9/a64. Feel free to use that as a starter (or not as it really is not much).

For me, I can try to help as much as I can. I own a pinephone and can test things, but I probably can't help much with lowlevel stuff (although I'd love to). I have to learn most things and I don't have much time to focus on learning it.

If you want to reach me off-list, my mail address is the same, but without the plus stuff, so just sirjofri@....
