Author: gber Date: Sat Mar 10 02:40:01 2012 New Revision: 232759 URL: http://svn.freebsd.org/changeset/base/232759 Log: Add nandtool utility. The nandtool utility can be used to perform various operations on gnand(4) devices (read, write, erase, read and write OOB area and to get info about NAND flash chip).
