Access entire device with mtdblock0

[Adam Yergovich]

Hello MTD,

There was a grand feature in the 2.4 flavor of MTD that i used wherein 
mtdblock0 was assigned the entirety of the device.  This made updating 
the flash image very easy.

I've since started messing around with 2.6 flavors, and while i have a 
working map that gives the partitions i can no longer access the entire 
device.  I've tried a few things without success to get it to work.

Any recommendations on a simple way to create a partition using the 
entirety of flash?
