From 60f26520e7bd4479dbebf77317c45fc2255ba2e8 Mon Sep 17 00:00:00 2001 From: Alexey Korolev Date: Tue, 16 Dec 2008 18:24:14 +0000 Subject: [PATCH] [MTD] LPDDR Makefile and KConfig We have two components to manage LPDDR flash memories in Linux. 1. It is a driver for chip probing and reading its capabilities 2. It is a device operations driver.
