Subject: [PATCH 6/7] unicore32: Use simpler API for random address requests
Currently, all callers to randomize_range() set the length to 0 and
calculate end by adding a constant to the start address. We can
simplify the API to remove a bunch of needless checks and variables.
Use the new randomize_addr(start, range) call to set the requested
address.
