Re: OLPC in 5.3? was Re: [PATCH v7 01/10] dt-bindings: olpc,xo1.75-ec: Add OLPC XO-1.75 EC bindings

Hi!

quoted

What is status of OLPC-1.75 in v5.3? IIRC most of the patches went in,
but I don't see suitable dts file in the tree. I tried porting one
from working (4.19 or so) kernel, but it was not quite trivial.

Is there time for dts to be merged?

Short answer is that it's not absolutely necessary. With a new enough
OpenFirmware, the firmware will just construct a correct FDT.

To upgrade your machine to the new firmware, just copy 
http://dev.laptop.org/~quozl/q4e00ja.rom to a FAT partition on a USB
flash stick and run "flash u:\q4e00ja.rom" from the "ok" prompt.
Then you'll be able to run stock mainline kernels happily.

Aha, good, thanks. That went smoothly.

That said, it might still be useful to have a DTS file in tree (for
reference, testing, machines with older firmware, etc.). I've now re-
sent the MMP2 devicetree update patch set with the DTS file included
and copied you on that one.

Yes: sometimes it is neccessary to modify the dts. I was changing the
kernel command line, for example.

As usual, I'm thankful for testing, reviews and acks.

I'll take a look. I tried 5.2 with defconfig from one of the branches
(olpc_xo175_defconfig), and that does not boot.

What config should I use? Is it enough to produce zImage and put it on
the flashdisk with olpc.fth file? Is there some kind of documentation
somewhere? :-).

Thanks and best regards,
