Subject: altos/stm: Allow core timer to be excluded from build
X-Git-Url: https://git.gag.com/?a=commitdiff_plain;h=ae26e6f1f7be989427ed2985c3e7fe63181aeb80;p=fw%2Faltos

altos/stm: Allow core timer to be excluded from build

This removes all of the support for the base 100Hz timer from the
system, saving space when not needed
