Subject: MIPS: fix annotation of _start and relocate_code
X-Git-Tag: v2016.03-rc1~299^2~15
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=113492988b0f471f9fe4f8f987a52c58a782d96f;p=oweals%2Fu-boot.git

MIPS: fix annotation of _start and relocate_code

Correctly annotate _start and relocate_code as functions to
produce more readable disassembly code generated by objdump.
