What's do other think? Should we add such an "enhancement" to the common CFI driver?
I would appreciate such a progress counter - if it does not slow down flash programming too much.
At a baud rate of 9600 bit/s one "xxxx KB " Message needs about 12,5 ms on the serial line. With a suggested granularity of 2^14 bit (= 16 KiB), programming time for 1 MiB increases about 0,8 s in the worst case. The worst case is, if the UART does not use any FIFO. With a FIFO the added time will only be about 1/10th, thus 0,08 s/MiB. For higher baud rates the additionally needed time will be even lower. So for me it would be OK, to add this featur to the common CFI driver.
