From 607edefb53ae5ca4120a7967c4cfed3184bb09d2 Mon Sep 17 00:00:00 2001 From: Paul Fertser Date: Thu, 3 Nov 2016 17:31:33 +0300 Subject: [PATCH] flash: nor: mdr: do not mass erase when clearing INFO memory The MDR parts have two kinds of memory: main (regular memory-mapped memory for code and data) and "info" (not memory-mapped). When OpenOCD is requested to erase the info memory block, it should do just that, instead of erasing everything including main memory.
