From 99d440cbba20b18a8d6583c4288ef3a820f370ce Mon Sep 17 00:00:00 2001 From: Cosmin Gorgovan Date: Sat, 29 Mar 2014 19:20:08 +0000 Subject: [PATCH] Flash/LPC2000: Add support for LPC11(x)xx, LPC13xx LPC11(x)xx and LPC13xx devices are mostly compatible with the lpc1700 variant of the LPC2000 driver, but use a fixed flash sector size of 4KB.
