In this release, we have few updates in core code, 4 new processor supports and SMP guest support.

New Features/Updates:

• Updated Host IRQ subsytem to have PIC driver APIs Linux compatible
• Updated Timer subsytem to have Clocksource driver APIs and Clockchip driver APIs Linux compatible
• Added support for having per-guest architecture specific context
• Centralized architecture specific interface header files to reduce duplicate header files
• Generic bitmap APIs under libs

New Emulators:

• ARM local timer emulator
• ARM A9MP private memory emulator

ARM 32-bit Port:

• Added support for ARM9 processor and Versatilepb host. We are able run basic test for Versatilepb guest on Versatilepb host.
• Added support for Cortex-A9 processor (UP) and VExpress-A9 host. We are able to boot unmodified Realview-PB-A8 linux guest on this port.
• Added support for Cortex-A15 processor (UP) and VExpress-A15 host. We are able to boot unmodified Realview-PB-A8 linux guest on this port.
• Fixes for sharing same exception vector base with Linux guest
• Fixes for supporting SMP Linux guest. We are able to boot unmodified VExpress-A9 SMP linux guest Realview-PB-A8, VExpress-A9, VExpress-A15, and BeagleBoard hosts

ARM 32-bit with VE Port:

• New CPU port supporting ARM processors with virtualization extensions
• We are able to boot multiple unmodified linux for Realview-PB-A8 guest on VExpress-A15 host using virtualization extension
• We are able to boot unmodified VExpress-A9 SMP linux guest on VExpress-A15 host using viruatlization extensions

x86 64-bit Port:

• Host apsace init works on QEMU & HW
• Host IRQ init works on QEMU & HW
