This patch extends the FSL UPM NAND driver from Anton Vorontsov to
support for the TQM85xx modules. Unfortunately, the hardware does
not support the R/B pins of the NAND chip and therefore the specified
maximum delay time must used. It therefore re-introduces the chip- 
delay
property.

Note: this patch is based on a patch Anton Vorontsov posted to this  
list:
     See http://ozlabs.org/pipermail/linuxppc-dev/2008-April/055587.html 
.
     It should show up mainstream soon.

You really need to CC the MTD list as this should go via them.  Also  
you're adding a new property and there should be updates to booting-w- 
o-f for it.
