/* Regarding performance:
*
* Short story - it might be best to leave the performance at
* current levels.
*
* You may see a jump in speed if you change to using
* 32bit words for the block programming.
*
* Its a shame you cannot use the double word as its
* even faster - but you require external VPP for that mode.
*
* Having said all that 16bit writes give us the widest vdd
* operating range, so may be worth adding a note to that effect.

/* Danger!!!! The STM32F1x and STM32F2x series actually have
* quite different flash controllers.
*
* What's more scary is that the names of the registers and their
* addresses are the same, but the actual bits and what they do are
* can be very different.
*
* To reduce testing complexity and dangers of regressions,
* a seperate file is used for stm32fx2x.
*
* Sector sizes in kiBytes:
* 1 MiByte part with 4 x 16, 1 x 64, 7 x 128.
* 2 MiByte part with 4 x 16, 1 x 64, 7 x 128, 4 x 16, 1 x 64, 7 x 128.
* 1 MiByte STM32F42x/43x part with DB1M Option set:
* 4 x 16, 1 x 64, 3 x 128, 4 x 16, 1 x 64, 3 x 128.
*
* STM32F7[4|5]
* 1 MiByte part with 4 x 32, 1 x 128, 3 x 256.
*
* STM32F7[6|7]
* 1 MiByte part in single bank mode with 4 x 32, 1 x 128, 3 x 256.
* 1 MiByte part in dual-bank mode two banks with 4 x 16, 1 x 64, 3 x 128 each.
* 2 MiByte part in single-bank mode with 4 x 32, 1 x 128, 7 x 256.
* 2 MiByte part in dual-bank mode two banks with 4 x 16, 1 x 64, 7 x 128 each.
*
* Protection size is sector size.
*
* Tested with STM3220F-EVAL board.
