No problem. I just had a look at the lib directory and noticed the crc7 
function and module is called crc7. I can imagine there are enough 
variants of that as well. Another variation is probably the polynomial 
used. Not sure how to factor in bit direction and polynomial into the name.

suggestions from my thumb:
- rnw_crc8: refers to Ross N. Williams who wrote the paper used for 
implementing this function.
- painless_crc8: refers to title of the paper "A Painless Guide to CRC 
Error Detection Algorithms".
- brcm_crc8: indicates where the function came from.

Other suggestions are welcome.
