From 18d500642fbae98beafcbf1bc9c812807c06e969 Mon Sep 17 00:00:00 2001 From: "Edgar E. Iglesias" Date: Thu, 26 Jan 2017 14:16:00 +0100 Subject: [PATCH] xen/arm: dt: Relax hw domain mapping attributes to p2m_mmio_direct_c Since the hardware domain is a trusted domain, we extend the trust to include making final decisions on what attributes to use when mapping memory regions. For device-tree configured hardware domains, this patch relaxes the hardware domains mapping attributes to p2m_mmio_direct_c. This will allow the hardware domain to control the attributes via its S1 mappings. Signed-off-by: Edgar E.
