From 578616299661e4a0bd723b35dc9489abb8077f08 Mon Sep 17 00:00:00 2001 From: Bibo Mao Date: Mon, 27 Nov 2023 12:02:31 +0800 Subject: hw/loongarch/virt: Align high memory base address with super page size With LoongArch virt machine, there is low memory space with region 0--0x10000000, and high memory space with started from 0x90000000. High memory space is aligned with 256M, it will be better if it is aligned with 1G, which is super page aligned for 4K page size. Currently linux kernel and uefi bios has no limitation with high memory base address, it is ok to set high memory base address with 0x80000000.
