[edk2-devel] [PATCH RFC edk2-platforms 4/5] Platform/Durian: Switch to unicore SEC implementation

["Ard Biesheuvel via groups.io" <ardb+git=google.com@groups.io>]

From: Ard Biesheuvel <ardb@kernel.org>

Spec adherent AArch64 systems use PSCI to manage secondary CPUs, and
only enter the execution level where UEFI and the OS live using a single
CPU.

This means using a SEC implementation of the MPCore variety is never
needed, and in practice, those drivers don't work correctly unless an
older version of the GIC is used (v2), which only supports up to 8 CPUs
and is therefore rare on server silicon.

So switch to the UniCore flavor, which should be functionally equivalent
if only a single CPU runs the UEFI firmware.
