Yes, but ...
We use lowlevel_init.S on a not yet public custom board to do some early, custom specific initialization. So I would vote to keep this.
But most probably non-mainline code isn't a reason to keep this?
Best regards
Dirk
so remove the file and the associated calls.

arch/arm/cpu/armv7/mx6/lowlevel_init.S is meant to contain code that is common to all mx6 boards. If you need some specific initialization for your board, I would suggest you to add such code into a C board file, or at least at board/<vendor>/<board_name>/lowlevel_init.S instead.

Fabio Estevam
