Hi,

This patchset introduces support for ICU (Interrupt Consolidation
Unit) of Armada7k8k SoC family. This unit allows to send a
message-based interrupts from the CP110 unit (South Bridge)
to the Application Processor hardware block. After dispatching
the interrupts in the GIC are generated. 

A basic version of the library is introduced, that
allows to configure a static mapping of the interrupt lanes
between CP110 interfaces and GIC. It is required for
the cases, where the OS does not support the ICU
controller on its own (e.g. ACPI boot).

The patches are available in the github:
https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/commits/icu-upstream-r20180712

I'm looking forward to review and any comments/remarks.

Best regards,
Marcin
