From 9cabe333e14435ed9c92bfcf31b1685634ca1acf Mon Sep 17 00:00:00 2001 From: Andrey Yurovsky Date: Thu, 19 Sep 2013 13:59:09 -0700 Subject: [PATCH] add support for Atmel SAM4L NOR Flash MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This adds a new NOR Flash driver, "at91sam4l", which supports the built-in Flash on Atmel's low-power SAM4L family of Cortex M4 MCUs. Parts and their geometry are detected automatically using the Chip ID and lookup schemes described in document 42023E–SAM–07/2013. Tested on AT91SAM4LC4CA via the SAM4L XPlained Pro development kit.
