Wolfgang Denk 700a0c648d Add common (with Linux) MTD partition scheme and "mtdparts" command
Old, obsolete and duplicated code was cleaned up and replace by the
new partitioning method. There are two possible approaches now:
* define a single, static partition
* use mtdparts command line option and dynamic partitioning
Default is static partitioning.
