Subject: board/freescale: Use unified setup_ddr_tlbs for spl boot and non-spl
 boot

We should use unified setup_ddr_tlbs() for spl boot and non-spl boot
to make sure 'M' bit is set for DDR TLB to maintain cache coherence.

Subject: dm: gpio: Add driver for MPC85XX GPIO controller

This patch adds a driver for the built-in GPIO controller of the MPC85XX
SoC (probably supporting other PowerQUICC III SoCs as well).

Each GPIO bank is identified by its own entry in the device tree, i.e.

gpio-controller@fc00 {
      #gpio-cells = <2>;
      compatible = "fsl,pq3-gpio";
      reg = <0xfc00 0x100>
}

By default, each bank is assumed to have 32 GPIOs, but the ngpios
setting is honored, so the number of GPIOs for each bank in configurable
to match the actual GPIO count of the SoC (e.g. the 32/32/23 banks of
the P1022 SoC).

The usual functions of GPIO drivers (setting input/output mode and output
value setting) are supported.

The driver has been tested on MPC85XX, but it is likely that other
PowerQUICC III devices will work as well.

Subject: dm: gpio: Add methods for open drain setting

Certain GPIO devices have the capability to switch their GPIOs into
open-drain mode, that is, instead of actively driving the output
(Push-pull output), the pin is connected to the collector (for a NPN
transistor) or the drain (for a MOSFET) of a transistor, respectively.
The pin then either forms an open circuit or a connection to ground,
depending on the state of the transistor.

This patch adds functions to the GPIO uclass to switch GPIOs to
open-drain mode on devices that support it.
