Changes made for Pathfinder 5226 controllers.

The firmware build for a 5226 is a .s19 file. For protection it was decided to encrypt this file for the B, E and F rev boards. This works by having a separate program encrypt the file and as it is being programmed the 5226 will decrypt it line by line. With the rev G K66 processor this didn't work from what seemed to be the bigger memory size. So the K66 build was not going to encrypted and the controller would not decrypt. After failures with Pathfinder trying to program the controller, encryption was looked at again.

The rev G board now accepts an encrypted build and will decrypt the file during programming.
