The eccmgr is at 0xffd06090, but the l2-ecc is at 0xffd06010? I would have thought from the placement the l2-ecc address would be inside the eccmgr's address? Dinh
Yes, this is confusing and I'll clarify/reorganize in the next series. The eccmgr is pointing to the ECC IRQ mask bits. These registers and the L2 ECC registers are organized in different areas within the system manager.
I'm actually redoing the series since the Arria10 IRQ handling is significantly different.
Since this change will affect the bindings and dti (the eccmgr will have the IRQs), please disregard this series.
