This adds initial device tree support for the following phones:
- Google Pixel 3 (blueline)
- Google Pixel 3 XL (crosshatch)
Both phone boards use the same identifiers and differ only slightly
in their connected peripherals.
Supported functionality includes:
- Debug UART
- UFS
- USB-C (peripheral mode)
- Display (Pixel 3 only, and the driver needs improvements)
- GPU
- Bluetooth
- Wi-Fi
The rmtfs region is allocated using UIO, making it technically "dynamic."
Its address and size can be read from sysfs:
$ cat /sys/class/uio/uio0/name
/sys/class/uio/uio0/maps/map0/addr
0x00000000f2701000
$ cat /sys/class/uio/uio0/maps/map0/size
0x0000000000200000
Like the OnePlus 6, the Pixel 3 requires 1 kB of reserved memory on either
side of the rmtfs region to work around an XPU bug that would otherwise
cause erroneous violations when accessing the rmtfs_mem region.

Did I really co-author this patch? Perhaps I contributed parts to it?
Perhaps I've just forgotten?
The patch and it's parts I used contained your S-off-by, so I added
Co-developed-by as I assumed parts of it was written by you.
That's hard about seeing patches downstream, as the history is not so clear.
Either way, I don't think I can say that I certify origin of the whole
patch.
Should I drop your the Signed-off-by then (and eventually all people who
didn't worked on the series I sent to upstream)?
Any parts that I did contribute, would have met the criteria, so you're
free to use those.
Thanks!
David
