Thanks! Any idea why the qemu with hard float configuration has a kernel panic
with linux-yocto?
init is going away so the kernel panics. Usually this means it couldn't
run the init on the rootfilesystem. Try adding keep_bootcon to your
kernel command line and see if that gives anymore debug.
I ran bitbake linux-yocto -c menuconfig
and noticed that the wrong ARM architecture was selected (it was using the same
one set using tune-arm926ejs.inc)
The thing is I don't see a defconfig anywhere, and I was wondering how the
linux-yocto kernel picks up the defconfig from the standard/base branch.
qemuarma9 would be building and booting from the
standard/arm-versatile-926ejs
branch, and re-use the base policies of the kernel.
It adds only the following board options, found in:

A TI OMAP 4430 Pandaboard or i.MX6 quad-core SABRE development kit platform
would do, but not sure how the linux-yocto kernel works, in terms of
pre-selecting the correct defconfig file.
