From e2e3ea891649f3a34e2ace974d47022c0ad7e314 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Tue, 5 May 2020 00:21:18 +0200 Subject: mpc83xx: remove redundant MPC83xx_RESET #define This macro is only used (tested for existence) in mpc83xx.c, which unconditionally includes mpc83xx.h where it is unconditionally defined. Removing it makes the remaining code easier to read.
