[Ltib] YAFFS2 tool/deployment method

[Peter Barada]

Attached are components containing a new mkyaffs2image tarball, patches and .spec file that can deal with a device table, and can be used by LTIB to create a YAFFS2 root filesystem image as a new YAFFS2 deployment method.

The following patch to current LTIB CVS should get it running (my LTIB version is based on version 8.4.1 and hacked up pretty hard so YMMV):

I've used it successfully to create a YAFFS2 image that I can boot my OMAP35x boards as the root filesystem(once burned via u-boot).  Hopefully people find this useful...
