-Subject: [PATCH 15/16] xen_arm: Initialize RAM and add hi/low memory regions
-
-In order to use virtio backends we need to initialize RAM for the
-xen-mapcache (which is responsible for mapping guest memory using foreign
-mapping) to work. Calculate and add hi/low memory regions based on
-machine->ram_size.
-
-Use the constants defined in public header arch-arm.h to be aligned with the
-toolstack.
-
-The toolstack should then pass real ram_size using "-m" arg.
-If "-m" is not given, create a QEMU machine without IOREQ, TPM and VIRTIO to
-keep it usable for /etc/init.d/xencommons.
