Gary,

Clearly, the README is meant for the new people, who might find it too 
complicated for the above fixes to be applied in order for them to avoid using 
Angstrom. But you are correct, besides known isues with gcc-4.6 not working 
for some components and hence requiring meta-oe; SOC_FAMILY and systemd 
dependency in recipes-misc/images were the only other two things requiring 
meta-angstrom layer.

You can try the updated meta-ti now, as it should solve those dependencies, 
thanks to Koen's latest patches. Please let us know how it works for you. 
Thanks.
