I would love to, but as it stands, this is still the best we can get for the 
MPC5121e :-(
I took that branch, merged the MBX patch in from the LTIB and ported the new 
NFC driver from the 'mpc512x' branch back to this one, since the original 
driver is buggy. 
The latest OpenGL-ES libraries and MBX drivers released are closed-source, 
buggy, but stable and seem to work well if your program doesn't do the kinds 
of things that make it crash. 
If you know the limitations of this and can live with it, it might be 
bearable... I don't have any other option :-(
