Roy, Ioana,

Would it be ok to add the following patch on top of the series?
It's a dependency for dpseci object.
If not added now I fear it won't be accepted until dpaa2-ethernet
moves out of staging, thus gating dpseci upstreaming.

Thanks,
Horia

39163c0ce0f48 ("staging: fsl-dpaa2/eth: Errors checking update")
added bits that are not specific to the WRIOP accelerator.

Move these where they belong (in DPIO) such that other accelerators
can make use of them.
