Cache On/Off/Configure 'C' Code API BSL

I needed one of the above a few weeks ago and hunted these forums and the downloads and could never find one.  It appears it is no longer part of the BSL.

I wrote one and am giving it to the community so no one else needs to reinvent the wheel.  I didn't see an attachment mechanism so I pasted the code in place below.  This blog editor mangled it pretty badly and I had to do manual patchup, so if it doesn't compile, it is likely 1-2 chars of typos.

TI, you can do better.  As you can see, this isn't much code, but it does take TIME and TESTING to get a reliable package.  This one is.  I have been using it for several weeks and have turned cahce on/off/sizes and seen the measured code execution time effects.

TI, please consider including something like this in future BSL releases.

Thanks for considering it, Chris

Example usage:

      CACHE_Init_L2  ( CACHE_L2MODE_DISABLED ) ; // I am using all of L2 for my fast arrays
      CACHE_Init_L1P ( CACHE_L1MODE_32KB ) ;
      CACHE_Init_L1D ( CACHE_L1MODE_32KB ) ;

evmc6748_cache.h: (I followed the naming convention so it even looks like it belongs in the BSL!)
