[Minios-devel] [UNIKRAFT PATCHv4 16/23] plat/kvm: Invalidate D-Cache that may have been modified for Arm64

[Jia He <justin.he@xxxxxxx>]

From: Wei Chen <wei.chen@xxxxxxx>

DTB, TEXT and RODATA would not be modified while booting, so we just
need to invalidate and clean the area that may have been modified:
DATA, BSS, PAGETABLE and BOOTSTACK.
