Suspend to RAM support for Xen on arm64

[PATCH 06/16] xen/arm: Introduce system suspend config option

Posted by Mykola Kvach 4 days, 12 hours ago

From: Mykola Kvach <mykola_kvach@epam.com>

This option enables the system suspend support. This is the
mechanism that allows the system to be suspended to RAM and
later resumed.
