Doh. That's what I get for looking in mk.* fragments instead of conf files.
is setting CPUFLAGS in the conf file preferred to adding the option to
CFLAGS in the mk fragment?
Also, is "-march= -mtune=" preferred to "-mcpu=" even if the kernel is only
going to run on a specific arm cpu?
Our current approach is to set -mcpu in the mk fragment, but that's
just what I stumbled on, and we'd rather be consistent with other
Thanks for all the help.
