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

[Ben Dooks]

[-- 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.
