Dear Ryan Mallon,
Did you have any additional changes you want made for the Snapper9260/9G20 patches other than adding a MAINTAINERS entry and rolling the boards.cfg change into a single patch?
Yes, the following things should be changed:
1. sort the boards.cfg entry to the right place. See top of boards.cfg for the rules. bluewater would be between atmel and emk ;)
2. #define SOMETHING 1. The "1" is depreciated if it serves no numeric meaning. Remove them in your board config. (Make sure the white space goes as well)
3. SZ_* macros are depreciated. Use numeric values. (256 << 20) is preferred to denote 256MiB.
Sorry I had no time to look deeper into details, but it looked good otherwise.
Can you confirm that the code builds and runs after the changes? I can't verify the "runs" part...
Best Regards, Reinhard
