Our recommendation is to use "virt":

Cortex-A9 and -A15 are very close -- any application level
code built for the A9 should run fine on QEMU's A15 model.
The kernel will obviously need to be built with "virt" board
support and Cortex-A15 support enabled, but you need to
build a kernel that works for the board model you select anyway.
