From: Philippe Mathieu-Daudé Date: Sun, 6 Dec 2020 19:29:00 +0000 (+0100) Subject: hw/mips: Move address translation helpers to target/mips/ X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2fd9c5ad4449c862932b21e8f6b4573cc50b9ae8;p=qemu.git hw/mips: Move address translation helpers to target/mips/ Address translation is an architectural thing (not hardware related). Move the helpers from hw/ to target/. As physical address and KVM are specific to system mode emulation, restrict this file to softmmu, so it doesn't get compiled for user-mode emulation.
