Translate IRQs by implementing of_xlate() as required by
irq_get_by_index() to parse interrupt properties.
Map DT interrupts to ARM GIC interrupts as follows:
- Interrupt numbers ID32-ID1019 are used for SPIs
- ID0-ID15 are used for SGIs
- ID16-ID31 are used for PPIs

Add a generic driver that binds to armv8 CPU nodes. The generic driver allows
- to enumerate CPUs present in a system, even when no other driver binds it
- generates ACPI SSDT code for each CPU
- Fill the ACPI MADT table (implemented in a follow up patch)
The newly introduced code could also be reused on other CPU drivers that are
compatible with armv8.
TEST: Booted on QEMU sbsa and verify the driver binds to CPU nodes.
Confirmed with FWTS that all ACPI processor devices are present.

Rename 'ahci_mvebu' to 'ahci_generic' and select it by default.
The AHCI driver contains no SoC specific code and only expects the
base address to be passed, thus rename it to ahci_generic and add the
DT compatible string "generic-ahci".
Update existing defconfigs to use the new Kconfig name as well.

Allocate memory for ACPI tables in generic acpi code. When ACPI wasn't
installed in other places, install the ACPI table using BLOBLISTs.
This allows non x86 platforms to boot using ACPI only in case the
EFI loader is being used, since EFI is necessary to advertise the location
of the ACPI tables in memory.

Since ACPI 2.0 the RSDT is deprecated and the XSDT should be preferred.
Until now the RSDT and XSDT entries were keept in sync as all platforms
that installed ACPI tables placed them below 4GiB and thus the address
would fit into the 32bit RSDT.
On platforms that do not have usable DRAM below 4GiB, like QEMU sbsa,
the RSDT cannot be used. Allow both RSDT and XSDT to be null and only
fill those tables that are present in acpi_add_table().
TEST: Fixes a crash on QEMU sbsa and allows to boot on QEMU sbsa.

ADSP-SC5xx is a series of ARM-based DSPs.
This comprises the armv7 based SC57x, SC58x and SC594 series, and the
armv8 based SC598.
This patch series includes configurations, init code, and minimal DTs
to enable Analog Devices' evaluation boards for these SoCs to boot
through SPL and into U-Boot Proper, as well as devicetree schemas for
the added DTs.
This patch series depends on ("arm: Add Analog Devices SC5xx Machine

Moves common options between all SC5xx series boards to the ARCH_SC5XX
option instead of duplicating them.
Also, it was possible to select multiple of the SoC support options.
Given a U-Boot binary can only support a single platform, this moves
the SoC selection to a `choice`, making them mutually exclusive.
