Subject: target/hexagon: Convert to 3-phase reset
X-Git-Tag: qemu-xen-4.18.0-rc5~385^2~21
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=ab85156d8aaaa2b301fe16efee35df8a35f2b33d;p=qemu-xen.git

target/hexagon: Convert to 3-phase reset

Convert the hexagon CPU class to use 3-phase reset, so it doesn't
need to use device_class_set_parent_reset() any more.
