Add initial board support for the Pixel 6 phone code named Oriole. This
has been tested with a minimal busybox initramfs and boots to a shell.

Space after comma. Maybe also make this line consistent for all added
files. Checking existing files, it's usually spelled "Copyright (C)
<years>, Google LLC."

Btw, I forgot to mention in my review for PATCH #18: please double
check the commit message, there are some issues with punctuation
there.

Just wanted to say: I think you are doing a great job with this
platform, and I can only imagine how hard it can be when you can't
actually tinker with the bootloader source code. But I do appreciate
that you was able to minimize stuff like earlycon, ect, etc :) And
this one actually LGTM.

I've made it match the other files I've added in v6 (by removing the
,). There seems to be a lot of variation upstream as to whether a . is
used at the end or not so I've left that as it was.
