From c591f109c3ad1cdc66b3ba241c6be95f789c3410 Mon Sep 17 00:00:00 2001 From: Owen Kirby Date: Tue, 25 Oct 2016 15:48:56 -0700 Subject: at91sam4: Add flash description and chipid for SAM4Cxx variants. Chip ID and flash layout taken from Atmel-11102F-ATARM-SAM4C32-SAM4C16-SAM4C8-SAM4C4-Datasheet_27-Mar-15 and tested on a SAM4C32-EK (rev A).
