From 6f7c7353004e2ff9709b326a4008ce8ea63d9270 Mon Sep 17 00:00:00 2001 From: gber Date: Thu, 17 May 2012 10:11:18 +0000 Subject: Import work done under project/nand (@235533) into head. The NAND Flash environment consists of several distinct components: - NAND framework (drivers harness for NAND controllers and NAND chips) - NAND simulator (NANDsim) - NAND file system (NAND FS) - Companion tools and utilities - Documentation (manual pages) This work is still experimental. Please use with caution.
