[patch 0/4] Simtec patches for new Kirkwood based boad

[Ben Dooks]

A fix for the RTC driver, updates for using RnB with the Orion NAND
driver and the machine definition for the DTCOMMOD.

Is there anytone currently picking up mach-kirkwood patches or should
this go to Russell's patch tracker?

[patch 2/4] kirkwood: allow machines to register RnB callback

[-- Attachment #1: slinux/arm/kirkwood/allow-mtd-ready-not-busy-registration.patch --]
[-- Type: text/plain, Size: 1855 bytes --]

Add a kirkwood_nand_init_rnb() call to allow boards which
have RnB line detection to register this instead of a
static delay.

What's the purpose of that comment there?

And isn't that comment misplaced too?

You do have a PCIe slot/device, right?

Other than that, ACK.

I usually do, and push them to git://git.marvell.com/orion.
But I don't mind if you want to push them to the patch system instead.
