From 2536f18bfa22eacc8d39d5b68762374f4bca8986 Mon Sep 17 00:00:00 2001 From: Patrice Chotard Date: Fri, 9 Feb 2018 13:09:55 +0100 Subject: [PATCH] arch-stm32: Factorize stm32.h for STM32F4 and F7 For STM32F4 and F7 SoCx family, a specific stm32.h file exists. Some common defines are duplicated or even unused in each of these stm32.h. Factorize all common definition in arch/arm/include/asm/stm32f.h and keep specific definitions in each arch/arm/include/asm/arch-stm32fx/stm32.h.
