Here is a patch to make MPC8266ADS its own platform. Instead of creating a new platforms/ads8266.h header, I could have inserted conditional compiles into the ads8260.h for the memory map differences.
Note: This is enough to get the kernel to build, boot and run. There are other issues that still need to be addressed.
