I use the redboot bootloader to flash image (using fis create), if I 
flash with lenght parameter same as image size it won't work, cause 
after that there is mtd/2 which is length of image and mtd/3 which 
contains rest of free flash (and I want mtd/2 to use all available flash).
I'll try to create image using legth of free flash and write rest of it 
after jffs2 image (unused part) with 0xFF.
