Subject[PATCH 2/3] ACPI / ACPICA: Add new features for MADT which introduced by ACPI 5.1
Date
From: Tomasz Nowicki <tomasz.nowicki@linaro.org>

Add new features for MADT which introduced by ACPI 5.1:
-comment on the GIC ID field of the GIC structure which is replaced
by CPU Interface Number.
-add new fields: Redistributor Base Address, GICV, GICH, and MPIDR.
-add new structures for GIC MSI frame and GICR.
-add flag definition for GICC flags.
