Once you have verified that the e300c3 binaries are functional, please send a 
your updated tune to the oe-core list... or if you prefer send it to me and I 
can review it and submit it (with your permission) to the oe-core list.

I'm interested in keeping the tunes updated as much as reasonable for a growing 
list of supportable cores.

BTW isn't the e300c3 a hard-float (standard classic PPC floating point?)  If so 
be sure to change the TUNE_FEATURES to fpu-hard.
