The sector erase might take very long when there are a lot of sectors to 
erase, say 12 min to 50 min for 1024 sectors on the 10m50 board. Without 
the display of progress, it will look like the board hangs.

The dotting code comes from the old cfi_flash.c. Some other parallel 
flash have this, but not spi-flash. It is trivial to add though.

Best regards,
Thomas
