Details

Here's a patch to create a fixed point math library within Rockbox. It can be shared between the core and the plugins. It shouldn't lead to any increase in code size if the functions within it are not used.

Currently only two functions are available, fsincos and fsqrt, along with various macros for using the EMAC unit on Coldfire.
