I got it. The first internal release of CRUX ARM HF for Genesi EfikaMX i.MX515 is ready.
This full hardware floating point release still includes only core packages and it has been started from scratch.
Btw, The CRUX ARM Team is already able to provide a full EfikaMX (i.MX515) support with the gnueabi/softfloat official release.
