[flashprog] Preparing for flashprog v1.2

Hi all, we're preparing for our next release v1.2 [1]. This one should be particularly interesting for developers: With multi i/o and QPI support, and the right programmer, external flashing can be a lot faster now. There's a new driver for FTDI FT4222H USB-to-SPI bridges -- probably our fastest supported programmer -- and Dediprog SF600 users benefit as well. Please grab the RC and test it :) As usual, the code is available through the tag `v1.2-rc1', and as tarball [2]. Cheers, Nico [1] https://flashprog.org/wiki/Flashprog/v1.2 [2] https://flashprog.org/releases/flashprog-v1.2-rc1.tar.bz2
