b065403710 ARM: orion: Fix Orion5x GPIO regression from MPP cleanup
Patchset "ARM: orion: Refactor the MPP code common in the orion
platform" broke at least Orion5x based platforms. These platforms have
pins configured as GPIO when the selector is not 0x0. However the
common code assumes the selector is always 0x0 for a GPIO lines. It
then ignores the GPIO bits in the MPP definitions, resulting in that
Orion5x machines cannot correctly configure there GPIO lines.

The Fix removes the assumption that the selector is always 0x0.
In order that none GPIO configurations are correctly blocked,
Kirkwood and mv78xx0 MPP definitions are corrected to only set the
GPIO bits for GPIO configurations.

This third version, which does not contain any whitespace changes,
and is rebased on v3.3-rc2.

527ef0550d ARM: Kirkwood: Add configuration for MPP12 as GPIO
The MPP12 is listed in the 6281 HW manual as output only but the iconnect
board from iomega is using it as GPIO (there's a button connected on it). So,
I'm adding a definition for the MPP12 as GPIO. As I've no informations about
this and which kirkwood are "affected", I'm adding a new #define instead of
modifying the current one for MPP12.

b2f427a108 ARM: orion: Refactor the MPP code common in the orion platform
mv78xx0 and kirkwood use identical mpp code.

It should also be possible to rewrite the orion5x mpp to use this
platform code.

0100defd28 [ARM] Kirkwood: MPP initialization code
This allows for board support code to set up their MPP config if the
bootloader didn't do it all or did it wrong.  This also allows to
register usable GPIOs.
