From b0b4b12bbe74d94137f871d8063bc55225fb2e85 Mon Sep 17 00:00:00 2001 From: Marti Bolivar Date: Mon, 11 Jun 2012 23:30:20 -0400 Subject: Add stm32_private.h. This will hold STM32-related things that I'm not sure are well-thought out enough to go into . Currently, it contains an accessor routine that tells you the purpose of the memory block containing an address.
