Tim Newsome c5dee66a71 Redo fespi flash algorithm (#384 ) * WIP, rewrite of flash algorithm. Just put all the flashing logic into the algorithm, instead of using an intermediate format. This should reduce total data written while flashing by about 9%, and also makes the code much simpler. Change-Id: I807e60c8ab4f9f376cceaecdbbd10a2326be1c79 * New algorithm works. Speeds up Arty flashing another 9%. wrote 2228224 bytes from file /media/sf_tnewsome/SiFive/arty_images/arty.E21TraceFPGAEvaluationConfig.mcs in 86.784538s (25.074 KiB/s) verified 2192012 bytes in 6.693336s (319.816 KiB/s) 8.66user 13.03system 1:33.91elapsed 23%CPU (0avgtext+0avgdata 12272maxresident)k Change-Id: Ie55c5250d667251be141cb32b144bbcf3713fce4 * Fix whitespace.
