[PATCH v2 0/3] arm64: dts: hi3798cv200: fix GICR size, add cache info, maintenance irq and GICH, GICV spaces

[Yang Xiwen via B4 Relay]

They are tested on a hi3798mv200 board in fact. Though the 2 SoCs are
highly similar and the CPU should be the same. Still, Tested-by are
welcomed.

The patchset fixes some warnings reported by the kernel during boot.

The cache size info is from Processor_Datasheet_v2XX.pdf [1], Section
2.2.1 Master Processor.

The cache line size and the set-associative info are from Cortex-A53
Documentation [2]. Dts for other SoCs are also a good reference.

>From the doc, we know L1 i-cache is 4-way assoc, L1 d-cache is 2-way
assoc and L2 cache is 16-way assoc. Fill the dts props accordingly.

Also, to use KVM's VGIC code, we need to add GICH, GICV and maintenance
IRQ to the dts. They are added with verification.

Dear maintainers, maybe consider Cc to stable too?
