Introduce nandsim command for develop/test nand mtd software. Based on the nandsim kernel module. Don't know the version anymore. The data which nandsim holds are in malloc space. The original module can use a file to operate on this. I removed this implementation, because it used the page-cache and I don't have a page-cache in barebox. I used nandsim in the following szenario: - barebox sandbox system with -i command to get a /dev/fd# device. - in barebox system you can use 'cp /dev/fd# /dev/nandsim#. - do some testing things on /dev/nandsim# - afterwards writeback with /dev/nandsim# /dev/fd# This works for example with a envfs image. Maybe I will add to synchronize with /dev/fd#(or another file) directly on changes. It needs a high malloc space and a high max argument number for commands. Please look at help text to see all parameters. I don't test all of these. I added two parameters to supply a random seed and to manipulate a bitflip_chance per page. To manipulate the bitflip_chance is not a nice solution at the moment. I send this patches, because maybe somebody can use it to test things with ubiformat. The nandsim implementation is not done yet!
