Update of /home/cvs/mtd/util
In directory phoenix.infradead.org:/tmp/cvs-serv2259/util

Modified Files:
	eraseall.c nandwrite.c 
Log Message:
From: 	Pantelis Antoniou <panto at intracom.gr>

The following patch fixes nandwrite/eraseall to work correctly on NANDs 
with the current mtd code.

There is a new option for nandwrite -a/--autoplace which places the OOB
bytes according to the autoplaced OOB of the current code.
