From 5337e01c09e19573758efbc57a7f7e972d78ab3f Mon Sep 17 00:00:00 2001 From: Marti Bolivar Date: Fri, 18 Nov 2011 17:24:14 -0500 Subject: RCC: Break out some portable functionality from stm32f1/. Portions of rcc_clk_enable(), rcc_reset_dev(), and rcc_set_prescaler() are portable; break these into static inline helpers in rcc_private.h. These guts of these are portable, but the arrays of registers etc. are not. Also add an extern declaration for rcc_dev_table into rcc_private.h. This lets us put rcc_dev_clk() into a newly resurrected libmaple/rcc.c, since that's portable.
