Micron NAND Rev D: initial reset

Hi, there...

I am trying to add mtd/nand driver support for the Micron MT29F2G08AADWP
(Revision D) on 2.6.26.  

According to Micron, the difference (aside from ID code) between Rev D and
the popular Rev C, is that the Rev D requires a RESET command to be issued
after power-up and before any other command is issued.

I am just diving into the nand driver, but I thought I would ask if there is
a good place to issue that RESET after power-up.

I do not see a specific "nand_reset()" function in nand_base.c  I assume I
need to create this function, then have it called within the platform driver
probe, just before the first command (nand_scan_ident).

Or is there a more generic way to go about this?  And if so, I assume
inserting a RESET command like this would be transparent to other NAND
chips?

Thanks & Regards,
Pete
