Hi Jerry:
I just assumed you went ahead. Yes, all seems good to me. It will be nice
to have this feature included as standard equipment.
Thanks, Warren

By default, st-flash works the same as before (there is no more chipid override in this pull request).
Now optionally, you can specify --flash=128k for example, to override the stm32f103c8t6 to assume 128k of flash instead of the default of 64k. This option accepts decimal (128k), octal 0200k, or hex 0x80k. Obviously leaving the multiplier out is equally valid, for example: --flash=0x20000
The size may be followed by an optional "k" or "m" to multiply the given value by 1024 or 1 Meg respectively.
Tests on the stm32f103c8t6 confirm that overriding the flash size is all that is required. I was still able to flash and read 128k without changing the chipid. I don't know if this will be true of all other devices but I suspect that they will.
