-Subject: [PATCH] trace-debug[stm]: Fix for BT/WLAN instability
-
-Pins under mop500_ske_pins array are used for different
-functionalities in snowball. Ex: GPIO161 pin configured
-for keypad here must stay configured as GPIO alternate
-function for operating PMU_EN pin of BT/WLAN chip in snowball.
-So forbid configuring these pins, for snowball
