So far an interrupt is triggered whenever there's at least one byte in the RX FIFO. This results in a unnecessarily high number of interrupts. Change this to generate an interrupt if - RX FIFO is half full (except if all bytes to read fit into the RX FIFO anyway) - end of transfer has been reached This way the number of interrupts can be significantly reduced.

2013-06-04	curve: move taia related functions into own header	Daniel Borkmann	1	-0/+159
