> +
> +Following ACPI spec:
> +On systems supporting GICv3 and above, GICR Base Address in MADT GICC
> +structure holds the 64-bit physical address of the associated Redistributor.
> +If all of the GIC Redistributors are in the always-on power domain,
> +GICR structures should be used to describe the Redistributors instead,
> +and this field must be set to 0.
> +
> +It means that we have two ways to initialize registirbutors map.
> +1. via GICD structure which can accommodate many redistributors as a region
> +2. via GICC which is able to describe single redistributor
> +
> +This patch is going to add support for second option.
> +Considering redistributors, GICD and GICC subtables have be mutually
> +exclusive. While discovering and mapping redistributor, we need to know
> +its size in advance. For the GICC case, redistributor can be in
> +a power-domain that is off, thus we cannot relay on GICR TYPER register.
> +Therefore, we get GIC version from distributor register and map 2xSZ_64K
> +for GICv3. [While the upstream version of this patch includes support for
> +GICv4, this backport omits it for simplicity.]
