+Subject: [PATCH 5/9] armv8: Make disabling HVC configurable when switching to
+ EL1
+
+On the BASER_FVP there is no EL3, so HVC is used to provide PSCI
+services. Therefore we cannot disable hypercalls.
+
+Create CONFIG_ARMV8_DISABLE_HVC (dependent on CONFIG_ARMV8_TO_EL1) to
+control whether to disable HVC exceptions in HCR_EL2->HCD
+
+Issue-Id: SCM-3728
+Upstream-Status: Inappropriate [other]
+  Implementation pending further discussion
