Release 0.9.20

some CAMs are really slow, increase timeout for link init
  more I2C debugging
  added README.md
  store ids for all links in link structure and add devid attribute
  - fix dynamic fmode changes - 69Mhz no longer needed for MaxS8 on GT link - show state in GT link change
  do not reference eth_rebuild_header in newer kernels
  fix reference to struct
  inc copyright year
  inc version number
  added support for SPANSION flash
