Revision:
22:1a58a518435c
Child:
26:a65fbb4bde5c
- Updated SPIFI code to allow BIOS to id chips not yet supported by DMSupport

- Updated QSPIFileSystem to be chip independant. Erase block info from SPIFI.cpp

- Split BiosDisplayAndTouch into BiosDisplay and BiosTouch

- Added BiosLoader with common functionallity

- Removed BIOS code from DMBoard

- Added first version of a touch listener
