From 301fe2c02ef0ca779d11dcedc2a081436360fbe3 Mon Sep 17 00:00:00 2001 From: Marti Bolivar Date: Tue, 10 Apr 2012 16:05:42 -0400 Subject: libmaple/spi: Fixups, move nonportable bits into libmaple/stm32f1. Standard family support refactoring: add STM32F1 series spi.h, spi.c, and move anything that won't port to STM32F2 there. As part of a general effort to be cleaner, remove the dependency on libmaple/util.h from libmaple/spi.h by not using BIT(). Also forward declare struct gpio_dev for spi_gpio_cfg() to remove that include.
