[U-Boot] [PATCH v6 17/17] arm: Remove unused relocate_code() parameters

Benoît Thébaudeau benoit.thebaudeau at advansee.com
Thu Feb 14 22:14:42 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.
