DTS for Zynq Microzed/Picozed

[Masahiro Yamada]

Hi Michal,


zynq-microzed.dts and zynq-picozed.dts are missing
in Linux tree.
(I do not see them in linux-xlnx on the GitHub, either)

Interestingly enough, I see both in U-Boot tree.


Is there some reason for that?
Otherwise, do you have a plan to port them to Linux?

microzed and picozed board are made by Avnet not by Xilinx and none
pushed support for these boards.

Yes they are in the u-boot because IRC Nathan wanted to have support there.

I was in touch with Avnet to improve support for their reference boards
but there is no conclusion from that discussion.
I have microzed here (I don't have picozed) but I don't have any
immediate plan to push support for this board to Linux without any
support from them.
And pushing board without regular testing is not the right way to go.

TBH: I am thinking to remove zynq boards which are not regularly tested.
For Linux this is not a problem because diff is just DTS and for U-Boot
with DM I believe we can be there soon.

Thanks,
Michal

I see.

I guess Avnet boards are attractive for hobbyists
because they are cheaper than xilinx ones.
Supporting them would be useful I guess,
but it is true that you have no obligation to do that.

I personally have better experience with digilent boards
(zybo for example). They just need to fix the problem with serial
console powering as is done on Xilinx boards.
But I agree Xilinx boards are pretty expensive and having cheap well
supported board will be the best option.
