From a39d1ced36fa1b46aa7f78ba988c300857ab7c7d Mon Sep 17 00:00:00 2001 From: Nemui Trinomius Date: Fri, 19 Dec 2014 08:24:25 +0900 Subject: [PATCH] lpc2000: Improve lpc2000 flash driver. This patch adds flash programming support for LPC5410x and LPC82x. And adds auto flash size detection for LPC800 series. Tested on below listed boards/chips.
