[U-Boot] [PATCH] m68k: code reformatting for all start.S files
Angelo Dureghello
angelo at sysam.it
Sun May 22 00:31:41 CEST 2016
This patch is style-related only, to reformat all the start.S code,
actually not following a coherent style inside single files and
between different cpu start.S files.
Linux format has been respected, as
- max line width at 80 columns
- one 8 cols tab between asm instructions and operands
- inline comments, where any, fixed at col 41
