Hi Laurentiu,

This patch series contains several fixes in preparation for SMMU
support on NXP LS1043A and LS1046A chips. Once these get picked up,
I'll submit the actual SMMU enablement patches consisting in the
required device tree changes.
Have you thought through what will happen if this patch ordering is not
preserved? In particular, a user installing a future U-Boot update with
the DTB bits but booting a stable kernel without this patch series -
wouldn't that regress dpaa then for our customers?
These are fixes for issues that popped out after enabling SMMU. 
I do not expect them to break anything.

Best Regards, Laurentiu
