Cortex-A9 MPCore r3p0 Generic Timer (aka Architected system timer) is not available in Cortex-A9. https://community.arm.com/message/8775 "Generic Timer is not an option on the Cortex-A9 (or A8 or A5) processors. The Generic Timer is an optional part of the ARMv7 architecture, and is not implemented by those three processors." Regards.
