[Xen-devel] [PATCH v3 0/3] xen/arm: Relax hw domain mapping attributes to p2m_mmio_direct_c

["Edgar E. Iglesias" <edgar.iglesias@xxxxxxxxx>]

From: "Edgar E. Iglesias" <edgar.iglesias@xxxxxxxxxx>

This relaxes the hw domains S2 mapping attributes to p2m_mmio_direct_c.

Eventually, I think we should allow guests to execute code from on chip
memories. We could follow-up with a patch that allows execution for
p2m_mmio_direct_c and p2m_mmio_direct_nc. Does that sound OK?

Cheers,
Edgar
