[poky] qemu armv7a

[Foinel]

Hello,
the default qemuarm build seems to be building for ARM926EJ-S as it
requires tune-arm926ejs.
Has anybody tried to build for armv7a (cortex a9) ? Have tried it
myself, by modifying the qemuarf.conf to require tune-cortexa9.inc
instead of tune-arm926ejs but the qemu machine won't boot anymore, it
just stays blank.
Any ideas, thoughts, suggestions regarding this would be appreciated.

Thanks
