Subject: common: Avoid including core_cm0plus.h and system_MKL26Z4.h.
X-Git-Url: http://git.code-monkey.de/?p=gps-watch.git;a=commitdiff_plain;h=97300537f2c9cbb9b27cacc0ae8b34283b96e13c

common: Avoid including core_cm0plus.h and system_MKL26Z4.h.

Manually add the required functions and macros instead.
