From 7f9f4678637f9ee1a999cc0870c4668f32e1a7eb Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Tue, 30 Jan 2007 11:16:16 +0100 Subject: [PATCH] [AVR32] Add PIOE device and reserve SDRAM pins The PIOE device was left out before because it muxes SDRAM pins (and is therefore a bit dangerous to mess with) and because no existing drivers had any use for it. It is needed for CompactFlash, however, and now that we have a way to protect the SDRAM pins, it can be safely added.
