Microblaze changes

Hi Tom,

here are microblaze patches for moving stuff to DM. This is the patch series which we postpone to next release. Buildman doesn't show any problems for mb, zynq_zc702 and zynqmp.

Thanks,
Michal

Hi Ricardo,

The reason for this break is moving serial driver to DM. Can you please tell us when you move platform to DM?

Thanks,
Michal

Hello Michal

I will give a look to it during the next week. Hopefuly by the end of it I can give you the patch or an educated estimated. Is this a good timeline for you?

Thanks!

Ricardo Ribalda

Hi,

ok. Let's wait one more week and I hope you will have SPL up and running.

Thanks,
Michal

I have allocated the whole Friday for this

Ricardo Ribalda

Hello

I will probably have something by next week. Is it ok?

Ricardo Ribalda

Hi,

do you want to me to wait? I have another sort of 50 patches which I would like to merge in this merge window to have enough time for testing.

Thanks,
Michal

Hi Tom,

Hi

My main concern is that the support for the board is not removed. I have one active product based on virtex5 ppc440.

Today I had to do some last minute support and now I am on a plane... Otherwise the patchset would be on your inbox.

I have taken a fast look over the required changes, and it is not that bad. Most of the hard work has already been done by you for mblaze.

Thanks for your understanding ;).

Hi,

You got max 2 more days to solve it. After that I will just disable uartlite support for this platform and will send updated pull request as we discussed with Tom.

Thanks,
Michal

Since this was on IRC, yes, we should disable the uartlite support to keep 440 building if this can't be resolved by enabling DM there instead as I don't want to block everything else on this. Thanks!

Tom
