2018-11-29lib: cordic: Move cordic macros and defines to header filePriit Laes
Now that these macros are in header file, we can eventually clean up the duplicate macros present in the drivers that utilize the same cordic algorithm implementation. Also add CORDIC_ prefix to nonprefixed macros.

2011-06-03lib: cordic: add library module providing cordic angle calculationArend van Spriel
The brcm80211 driver in the staging tree has a cordic function to determine cosine and sine for a given angle. Feedback received from John Linville suggested that these kind of functions should be made available to others as a library function in the kernel tree. The b43 driver also has a cordic angle calculation implemented. Cc: linux-kernel@vger.kernel.org Cc: linux-wireless@vger.kernel.org Cc: "John W.
