sh: mach-rsk: Update for parse_mtd_partitions() fallout.
Browse files Browse the repository at this point in the history
The RSK+ setup code was doing some pretty dubious things with
parse_mtd_partitions() in order to populate the physmap-flash map
platform data. The physmap-flash driver contains all of the functionality
that we require already, so simply drop the special casing and pad out
the platform data accordingly.
