Current implementation doesn't need delay, because code it self need 1 micro second per TCK cycle. This gives 1 MHz so it is correct for targets with 6 MHz CPU clocks and faster. This patch add special delay routine when TCKWAIT is 0. If TCKWAIT is non zero it is interpreted as delay in microseconds. This way it is easy to set longer TCK cycle if needed.
When small binary file is loaded, only part of flash could be erased. This feature speed up flash time. It is added only for files smaller than 512 kb, because this doesn't add much of complexity to erase routine.

This patchset improves JTAG performance and erase speed on STM32F4xx. I have tested it on the board.
