ARM: dts: i.MX6: fix usdhc3 pinmuxing on tqma6x ...

The usdhc3 pin group wrongly referred the SD4 pads instead of the SD3 pads.
This leads to issues when muxing the SD4_CMD and SD4_CLK pads for uart3.

This regression was introduced by code refactoring in commit a5207a6 ("ARM:
dts: i.MX6: drop usage of pin group defines").

ARM: i.MX6 Wandboard Quad: fix PBL UART MUX ...

Three variants of the Wandboard exist: WBSOLO, WBDUAL and WBQUAD.
For all variants, the external serial port is connected to UART1 via
PAD_CSI0_DATA10 (TX) and PAD_CSI0_DATA11 (RX). Unfortunately, the IOMUX
register adresses for this mux differ between i.MX6Q (WBQUAD) and others.
Make the UART IOMUX for PBL compatible for WBQUAD.

ARM: i.MX6 Wandboard: dont do MMDC Write Leveling Calibration ...

The hardware requirements to perform a write leveling calibration are
not fulfilled by the Wandboard modules.
IMX6DQRM §44.11.6 "Write leveling Calibration" Note2 states that the first
bit of each data byte group (D0, D8, ..., D56) from memory must be connected
to the same data bus bit on the controller, which is not given on the
Wandboard modules, resulting in unpredictable calib results and breaking the
WBQUAD 2GiB SDRAM setup. Similar restrictions exist for the i.MX6SD.

Remove this calibration and use the MPWLDECTRL defaults.

sandbox: fix registering multiple consoles ...

Consoles need to be registered with the "console" device name so that
they are probed by the correct driver. The barebox_register_console()
was already forcing this as it was overwriting the name that was being
passed as argument, but it was failing to provide a unique id for
each new console, so the underlying register_device() would just
return an error when wanting to re-register a device with device name
"console" and id 0.

We remove the unused name parameter from barebox_register_console() as
it is really nowhere used, and also specify DEVICE_ID_DYNAMIC as id,
so that a new unique device id is given to each newly registered
console device.

area where the stack is located for the PPC architecture.

On PPC the stack is below the barebox binary. Below the stack the malloc
area is located. Until this change some routines used the macros
from 'memory_layout.h', some other calculated their values by their
own - which resulted into an unrequested and unprotected stack area.
