We currently only use one slave, so drop for_each_slave and hardcode
slave[0] until we pass the proper context to the functions that makes
this hack unnecessary.

Instead of requiring a device pointer, add a functions to select
the pinctrl state based on a device node.
The AM33xx cpsw devicetree description has several subdevices with
pinctrl information attached to them. In barebox we do not handle
the subdevices as distinct devices, so the pinctrl is never configured
correctly and the mdio bus subdevice stops working. This patch makes
it possible to configure the pinctrl without having a device.

We want to check whether boarddata contains a valid dtb if it's inside
valid memory. This includes the base of SDRAM, so use '>=' instead of '>'.

CONFIG_MAXARGS is only used with the simple console support, so add
a 'depends on'. While at it, move it below the shell selection.

A function should either return an ERR_PTR or NULL on failure, but not both.
Let get_phy_device() return an ERR_PTR and fix the return checks in mdiobus_scan
and phy_device_connect.

| ARM: omap4: Use writel where appropriate

This introduces a single omap_init function which detects the
SoC and does all further SoC initialization. This is done to get
rid of initcalls without proper SoC protection. The same has been
done for i.MX already.

Devicetree probed cpsw devices won't have platform_data, so inline
the fields from slave_data instead of keeping a pointer.

The omap3 and omap4/am33xx spi cores differ in the offset of the
registers in the address space. Instead of encoding this into the
resources use the platform_device_id mechanism. This is done in
preparation for devicetree probe support where the address space
is in the devicetree and can't be adjusted.

Since we use the generic ns16550 driver we need the regshift property
to correcty access the UART.

For making #include <dt-bindings/...> work
We already have the necessary -I flag in dtc_cpp_flags, no nothing
needs to be done here.

Also import related functions gpio_request_one() and
gpio_free_array().
This commit imports code from linux 3.7 as
the more recent linux kernel versions use gpiolib descriptors,

gpiolib: use descriptors internally
Make sure gpiolib works internally with descriptors and (chip, offset)
pairs instead of using the global integer namespace. This prepares the
ground for the removal of the global gpio_desc[] array and the
introduction of the descriptor-based GPIO API.

The build of target tools fails on sandbox architecture.
We don't need any target tools in this case, so add a dependency.
