  Tested on snow, pit, pi (display does not yet work on Pi).
 
  Just to be clear, in your testing does the display not work on Pi? It
  seems to be ok here (with u-boot starting chainloaded from one of the
  KERN partitions)

 That's right, not in U-Boot. I think this is because some GPIOs need
 to be enabled to turn on the backlight etc. Maybe you have an EC which
 turns these on automatically?

 If current mainline is supposed to make the display work on Pi then I
 need to do some debugging. Please let me know.

 It does work on my machine, so i was wondering if it's a setup
 difference. I'm using the chained u-boot method (iotw the standard
 chromeos u-boot in flash starts main-line u-boot from mmc/SD), which
 might well mean that the GPIOs you're referring to are still turned on
 by the first u-boot (which it has to do to show me the unverified boot
 warning screen)?

 Yes that's right. Maybe Akshay / Ajay have ideas, or otherwise I can
 add this. I think it is two GPIOs, but it might be TPSCHROME also.
 Now, I have added support for peach_pi display in u-boot.
 Kindly check the patches.

It seems that these have not been applied. So Pi is not in a working
state in mainline.

When can these be applied please?

There is also the rpll_sdiv patch.

I found this when testing later patches.

Regards,
Simon
