EABI on Maverick Crunch

Notes on making a proper EABI cross compiler for Maverick Crunch (EP9302, EP93xx) processors

This is a bit of "higher order hacking" and not too trivial, but it works. Basic compile instructions are at: ARM Cross Compiler

1. Fixup the binutils (2.20) to store the mv registers, according to the patches at: http://www.freelists.org/post/linux-cirrus/Yet-another-MaverickCrunch-hardware-bug,14. Note that I did these patches by hand, since 2.20 is a bit different from 2.17.
2. Compile and install the renewed binutils.
3. Get the gcc-4.3.4 distribution from GNU
4. Apply the patches of Martin Guy <martinwguy@gmail.com>, found at http://martinwguy.co.uk/martin/crunch
5. Compile and install the renewed gcc.

The new gcc and g++ can now make FPU enabled code when using the additional command line options: -mcpu=ep9312 -mfpu=maverick -mfloat-abi=softfp
