/*
	2007-02-11 :-add option for SAM7A3
				-add in "CUSTOM_PCB", use instead of one of the demo boards.
 Modifications by Martin Thomas for the WinARM example :
   - define __inline as static inline
   - ramfunc for GNU-tools (see linker-script)
   - modifications for multiple submodels (7S64 and 7S256)
   - added definitons for OX SAM7-P
*/
