Thanks, Andrew

I'm still working on getting DFU Upload code running, and adding the SPI flash driver, will send a pull request later. Regards, Andrew

-- Commit Summary --
- initial commit a fully reworked project structure
- moved usb_descriptors to per-board config, adjusted params.
- minor fixes and cleanups
- added config option to strip usb suspend/resume code
- Set default options to -Os and no debug. Result is ~5.9KiB.
- Fixed maple target to compile (Not tested!)
- shut up another warning
- added README and TODO
- added missing usb_descriptor for maple target
- Additions to TODO
- shut up the last warnings from usb_regs.h
- Changed color scheme a little bit
- Added README.porting
- added myself to CREDITS
- Update TODO
- Made a bunch of vars volatile to work properly with -Os
- Added RUNAPP_ALT hack, see README.porting for details
- fixed typo
- wrapped bootloaderExitCondition in #ifdef's
- uncommented some quite critical code.
- implemented optional INFO endpoint support
- include config.h in usb.c
- te-stm32f103ret6kit: fix usb descriptors
- Added initial stuff for Motor Cortex Board
- added GPIOG definition
- move FLASH_PAGE_SIZE to boardconfig
- Fixed TODO/README added stubs for DFU refactor
- Moved IO routines to dfu_io.c, broken config for all boards
- fixed board configs to reflect recent dfu.c changes
- Fixed FLASH_PAGE_SIZE for maple, added MAPLE RET6 dummy. UNTESTED!!!
- Fixed typo in configs
- dfu: fixed errors in dfu_io
- fixed README
- Added a small dev README
- Initial stubs for dfu upload functionality
- Do an NVIC_SetVectorTable before jump
- Added xilinx sscu driver
- Added licencse stuff to xsscu. Let it be MIT
- Fixed flash corruption on copy
- Special commit with steroid and coffeine - dfu now works 10 times faster!
- mcortex: Fix USB disconnection handling

This is my total rework of dfu bootloder code, that might be userful for you. Most of the 'revolutionary' things are now done, everything should be stable now.
