Etienne Carriere 64cc6e91e8 ARMv7 may not support Virtualization Extensions ARMv7-A Virtualization extensions brings new instructions and resources that were supported by later architectures. Reference ARM ARM Issue C.c [DDI0406C_C]. ERET and extended MSR/MRS instructions, as specified in [DDI0406C_C] in ID_PFR1 description of bits[15:12] (Virtualization Extensions): A value of 0b0001 implies implementation of the HVC, ERET, MRS (Banked register), and MSR (Banked register) instructions. The ID_ISARs do not identify whether these instructions are implemented. UDIV/SDIV were introduced with the Virtualization extensions, even if not strictly related to the virtualization extensions. If ARMv7 based platform does not set ARM_CORTEX_Ax=yes, platform shall define ARMV7_SUPPORTS_VIRTUALIZATION to enable virtualization extension related resources.
