This is based on the patch sent by Alexander Fedorov with the following fixes/improvements: - Better error handling; - Clock is derived from PLL6 (obtained from netbsd); - No more unnecessary busy loops on interrupt handler; - style(9) fixes and code cleanup. I also want to thanks Martin Galvan who has sent an alternative implementation with some interesting fixes. Tested on CubieBoard2, Banana-Pi (thanks to netgate!) and Cubieboard1 (Pratik Singhal). This is intended to pave the way for the upcoming GSoC work (and make easier the build of images for the supported boards).
