Here is the branch with ZynqMP changes for DM.

http://git.denx.de/?p=u-boot/u-boot-microblaze.git;a=shortlog;h=refs/heads/serial-dm

I have added comments to commits.
The most problematic part for ZynqMP is that you have reverted
"fdt: Fix fdtdec_get_addr_size() for 64-bit"
(sha1: 5b34436035fc862b5e8d0d2c3eab74ba36f1a7f4) which is able to handle
address-cells = 2, size-cells = 1 case which ZynqMP is using.

Anyway you should be able to run u-boot on qemu.
Here is the log I am getting.

Please let me know if you need any input on this.

Thanks,
Michal
