Hi,

I recommend to write this kind on question on the mailing list. You
would probably get faster replies than I can do and also other people
would benefit.

Hi Luca, Peter,

Now that the zynqmp defconfigs have been bumped to a newer version of our software, I am thinking we should probably bump the zynq defconfigs as well.

As there is no PMU firmware, it is a much easier job.  However, of the 4 boards in buildroot, I only have a zc706 for testing.

The problem is I will need to touch the files in the board/zynq directory, so if I bump the zc706, I really need to bump all 4 board defconfigs to avoid build failures on the other boards.

Do either of you have the zynq microzed, qmtech or zed boards for testing?  If not, are you ok with updating all 4 defconfigs assuming 3 of them will only be build tested?

What are your thoughts?

Thanks for taking initiative to upgrade these defconfigs!

I used to have access to a ZedBoard, but unfortunately I cannot access
any of those boards anymore. However I would expect them to be extremely
similar with respect to booting: they are [variants of] the same SoC and
thus they have the same boot flow, and definitely they all are connected
to allow SD boot.

Thus I think it is absolutely reasonable if you update all of them,
checking all details carefully, build-test all of them and runtime-test
at least one on real hardware. At least it's what I have been doing in
the past: you can have a look at 'git log -3 014e97032465', as you can
see I did Run-time test one and Build-test the others.

Thank you for your positive feedback.

I have submitted a first patch which will make updating the zynq defconfigs easier.

I should have copied you on this, but since you are not responsible for the qmtech defconfig, the tool did not automatically add in your email address.

Anyway, I have an issue with the qmtech board because the device tree is not in mainline.  As I do not have a qmtech board to test, I would prefer to avoid touching the qmtech device tree, so it can work with a newer version of software.

The following patch isolates the qmtech board, so that I can update the other 3 zynq defconfigs without touching the qmtech defconfig.

Could you have a look and provide your feedback?
