Can I ask a question about this ... in difference from everyone in the
world who has APQ8070 DragonBoards I actually have the APQ8060
DragonBoard.
I have been booting this using the qcom-msm8660-surf.dts device tree
and it seems to work reasonably well, like the timer, intcon and stuff
is obviously in the right place.
But how similar is it really? I am told the CPU type may not be the
same even if the periphs seem to be in the same place.
Do I need a qcom-***8*60-dragonboard.dts at some point or is the
"surf" electronics similar to the APQ8060 dragon?
The board layout and electronics are actually all the docs I have, I
have no datasheet/trm for the APQ8060 per se, and no clue what the
"surf" board really is, so I'm a bit in the dark here.
Yours,
Linus Walleij

For the basic stuff like timer, serial console, etc. the surf and
the dragonboard are the same. The Scorpion CPU is the same
between them. The main difference is that the 8060 doesn't have a
modem.
We probably only need a qcom-***8*60-dragonboard.dts file when
the two diverge. That might be soon given that ssbi and the pmic
core are in place. Enabling something like the keypad driver
should be possible.
