[U-Boot] [PATCH v9 20/30] arm: Remove unused relocate_code() parameters

Benoît Thébaudeau benoit.thebaudeau at advansee.com
Wed Mar 6 19:59:26 CET 2013 

Commit e05e5de7fae5bec79617e113916dac6631251156 made the 2 1st parameters of
ARM's relocate_code() useless since it moved the code handling them to crt0.S.
So, drop these parameters.
