All,

Over the course of the last several months, I've been working on adding support to the kernel for MTD devices that exceed 2GiB in 
size.  In my particular case I have a need for 8GiB of NAND flash that appears as a single device.  I'm now ready to submit my 
(first ever) patch (please be kind :)  ).  Seriously, I've been on this list a LOT during this time and I've gotten nothing but 
great support, thank you to the entire list.

A couple of comments.  First and foremost, these patches don't completely change the MTD layer.  Due to my in-experience outside of 
what I was focused on (NAND/UBI/UBIFS/MTDCHAR) I felt it was best if I restricted my changes to what I knew.  If the community feels 
I need to take these changes into the rest of the kernel please advise.  Secondly, there were changes that I needed to make in 
mtd-utils, but I again only focused on the UBI sub-set.  mtd-utils no longer builds because of the changes, but I really do NOT feel 
qualified to make changes to the rest of mtd-utils as they're tools I don't use and don't understand.  The changes in mtd-utils are 
the same changes as in .../include/linux/mtd/mtd.h and .../include/mtd/mtd-abi.h.  If anyone has a suggestion as to how I should 
handle mtd-utils I would appreciate it.

Thanks again to everyone on the list who's answered my endless stupid questions.

Bruce
