[PATCH 1/3] target/arm: Check VSTCR.SW when assigning the stage 2 output


From: Idan Horowitz
Subject: [PATCH 1/3] target/arm: Check VSTCR.SW when assigning the stage 2 output PA space
Date: Sun, 27 Mar 2022 12:34:26 +0300

As per the AArch64.SS2OutputPASpace() psuedo-code in the ARMv8 ARM when the
PA space of the IPA is non secure, the output PA space is secure if and only
if all of the bits VTCR.<NSW, NSA>, VSTCR.<SW, SA> are not set.
