2012-02-26flash: add stm32f2x async flash loaderSpencer Oliver
This enable the stm32f2x flash driver to use the asynchronous algorithm support. Speed increase is as follows: before - wrote 1048576 bytes from file stm32f4x.bin in 30.453804s (33.625 KiB/s) after - wrote 1048576 bytes from file stm32f4x.bin in 23.679497s (43.244 KiB/s) This also fixes a bug that was in the old flash loader. The old loader waited while bit16 of the status reg was 0, the new loader waits until this bit is 0 as stated in the flash spec. Bizarrely this bug did not effect programming on any tested parts.

2012-02-13flash: fix incorrect stm32f2x/stm32f4x flash size registerSpencer Oliver
The ref manuals for the stm32f2x (RM0033 Rev4) and stm32f4x (RM0090 rev1) are unclear to the address of the flash size register (F_ID). According to contacts @ ST this is the correct address, the manuals will be updated in due coarse.
