[platforms: PATCH v2 0/6] Armada7k8k ICU support

[Marcin Wojtas]

Hi,

The second version of the ICU patchset brings all corrections
according to all review remarks. They were mostly style / naming
- detailed list can be found in the changelog below.

The patches are available in the github:
https://github.com/MarvellEmbeddedProcessors/edk2-open-platform/commits/icu-upstream-r20180713

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

Best regards,
Marcin

Changelog
v1 -> v2
* 1,6
  - Add Ard's RB

* 2
  - Change ICU_IRQ_TYPE to IcuIrqTypeLevel / IcuIrqTypeEdge

* 3
  - Use EFI_PHYSICAL_ADDRESS

* 4
  - Put a space after { and before }
  - Change enum values to IcuGroupXxx format

* 5
  - Use ICU_GROUP_REGISTER_BASE_OFFSET instead of a raw value in macros
  - Add missing parentheses and use sizeof (UINT32) in ICU_INT_CFG macro
  - Use mEfiExitBootServicesEvent - not initialized and STATIC
  - s/IcuConfigDefault/IcuInitialConfig/
  - Break to long lines

[platforms: PATCH v2 1/6] Marvell/Armada70x0Db: Set correct CP110 count

[Marcin Wojtas]

As a preparation for adding the ICU (Interrupt Consolidation
Unit) library implementation a correct CP110 count is required.
Do it for Armada70x0Db and fix depending XHCI/AHCI PCD's accordingly.

[platforms: PATCH v2 2/6] Marvell/Library: Introduce ArmadaIcuLib class

[Marcin Wojtas]

ICU (Interrupt Consolidation Unit) is a mechanism,
that 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.

This patch adds a basic version of the library, that
allows to configure a static mapping 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).

ICU (Interrupt Consolidation Unit) is a mechanism,

hardware block. After dispatching the interrupts in the
GIC are generated.

This patch adds a basic version of the library, that
allows to configure a static mapping between CP110
interfaces and GICv2 of the Armada7k8k SoC family.
