This should be a simple matter of grabbing the sources (using git),
setting your toolchain PATH, and running the compile.
Note that you might want to grab the kernel configuration from a
device running Yocto as a starting point. There are some bits
included in the Yocto configuration that will be useful
(including single-touch selection for Hannstar display and
I believe some udev-related updates from Fabio).
You can grab the kernel configuration out of /proc/config.gz on
a running system, and gunzip it into your kernel source tree as
file name ".config" to get an identical starting point.
There must be an easier way to access the Yocto-built cross compiler,
but it appears on my system under:
