From 66f75ca74ea11d0c242bd3773a7b31f07030c8e7 Mon Sep 17 00:00:00 2001 From: Marti Bolivar Date: Mon, 26 Mar 2012 17:38:32 -0400 Subject: [UNTESTED] Resurrect FSMC support. fsmc_sram_init_gpios() is now series-specific, so move its existing implementation to the F1 backend, and add libmaple/stm32f2/fsmc.c for the F2 backend. Delete libmaple/fsmc.c; it is now empty.
