2017-11-08	64deed1 Browse files » ARMv7: GICv2 driver can manage GICv1 with security extension ... Some SoCs integrate a GIC in version 1 that is currently not supported by the trusted firmware. This change hijacks GICv2 driver to handle the GICv1 as GICv1 is compatible enough with GICv2 as far as the platform does not attempt to play with virtualization support or some GICv2 specific power features. Note that current trusted firmware does not use these GICv2 features that are not available in GICv1 Security Extension.

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.

As ARM-TF expects AARCH to be set, ARM_ARCH_MAJOR==7 mandates AARCH=aarch32. The toolchain target architecture/cpu is delegated after the platform configuration is parsed. Platform shall define target core through ARM_CORTEX_A<x>=yes, <x> being 5, 7, 9, 12, 15 and/or 17. Platform can bypass ARM_CORTEX_A<x>=yes directive and provide straight the toolchain target directive through MARCH32_DIRECTIVE.

Building the UniPhier platform in parallel with TRUSTED_BOARD_BOOT=1 could fail due to non-existing directory.
