From b1121e2a182dc8f22e7cfa2d8374199505d27ab8 Mon Sep 17 00:00:00 2001 From: Huacai Chen Date: Mon, 5 Jul 2021 20:42:04 +0800 Subject: ACPI: Add LoongArch support for ACPI_PROCESSOR/ACPI_NUMA We are preparing to add new Loongson (based on LoongArch, not MIPS) support. LoongArch use ACPI other than DT as its boot protocol, so add its support for ACPI_PROCESSOR/ACPI_NUMA. Signed-off-by: Huacai Chen Signed-off-by: Rafael J.
