I recommend that we create a new meta-qemu layer, to support development of
qemu machine configurations for
qemuarmv7 (useful for emulating TI OMAP 3 based platforms)
qemuarma9 (useful for emulating TI OMAP 4 and Freescale i.MX6 platforms)
qemuarmv8 (for AArch64 platforms)
qemumips64 
etc

That should just about cover current ARM A8, A9, A15 and MIPS64.

Best regards,
