Given a device tree node, a property name and an index, the new function
fdt_get_string_index() will return in an output argument a pointer to
the index'th string in the property's value.
The fdt_get_string() is a shortcut for the above with the index being 0.

This is the USB host controller used on the Altera SoCFPGA and Raspbery Pi.
This code has three checkpatch warnings, but to make sure it stays at least
readable and clear, these are not fixed. These bugs are in the USB request
handling combinatorial logic, so any abstracting of those is out of question.
Tested on DENX MCV (Altera SoCFPGA 5CSFXC6C6U23C8N) and RPi B+ (BCM2835).

Adjust the driver so that leaf functions take a pointer to the serial port
register base. Put all the global configuration in the init function, and
use the same settings from then on.
This makes it much easier to move to driver model without duplicating the
code, since with driver model we use platform data rather than global
settings.
The driver is compiled with either the CONFIG_PL010_SERIAL or
CONFIG_PL011_SERIAL option and this determines the uart type. With driver
model this needs to come in from platform data, so create a new
CONFIG_PL01X_SERIAL config which brings in the driver, and adjust the
driver to support both peripheral variants.

This feature provides for init of a single SPI port for the soft SPI
feature. It is not really compatible with driver model since it assumes a
single SPI port. Also, inserting SPI init into the driver by means of
a #define is not very nice.
This feature is not used by any active boards, so let's remove it.

U-Boot includes a SPI emulation driver already but it is not explicit, and
is hidden in the SPI flash code.
Conceptually with sandbox's SPI implementation we have a layer which
creates SPI bus transitions and a layer which interprets them, currently
only for SPI flash. The latter is actually an emulation, and it should be
possible to add more than one emulation - not just SPI flash.
Add a SPI emulation uclass so that other emulations can be plugged in to
support different types of emulated devices on difference buses/chip
selects.

Add a uclass which provides access to SPI buses and includes operations
required by SPI.
For a time driver model will need to co-exist with the legacy SPI interface
so some parts of the header file are changed depending on which is in use.
The exports are adjusted also since some functions are not available with
driver model.
Boards must define CONFIG_DM_SPI to use driver model for SPI.

The driver model supports two ways for passing device parameters;
Device Tree and platform_data (board file).
Each driver should generally support both of them because some
popular IPs are used on various platforms.
Assume the following scenario:
- The driver Foo is used on SoC Bar and SoC Baz
- The SoC Bar uses Device Tree control (CONFIG_OF_CONTROL=y)
- The SoC Baz does not support Device Tree; uses a board file
In this situation, the device driver Foo should work with/without
the device tree control. The driver should have .of_match and
.ofdata_to_platdata members for SoC Bar, while they are meaningless
for SoC Baz; therefore those device-tree control code should go
inside #ifdef CONFIG_OF_CONTROL.
The driver code will be like this:
#ifdef CONFIG_OF_CONTROL
static const struct udevice_id foo_of_match = {
{ .compatible = "foo_driver" },
{},
}
static int foo_ofdata_to_platdata(struct udevice *dev)
{
...
}
#endif
U_BOOT_DRIVER(foo_driver) = {
...
.of_match = of_match_ptr(foo_of_match),
.ofdata_to_platdata = of_match_ptr(foo_ofdata_to_platdata),
...
}
This idea has been borrowed from Linux.

This patch adds board support for the Toradex Apalis T30 a computer on
module which can be used on different carrier boards.
For the sake of ease of use we do not distinguish between different
carrier boards for now as the base module features are deemed
sufficient enough for regular booting.
The following functionality is working so far:
- eMMC boot and environment storage
- Gigabit Ethernet (once Thierry's PCIe as well as my E1000 resp. i210
fixes hit mainline)
- MMC/SD cards (both 8-bit as well as 4-bit slot)
- USB client/host (dual role port as client e.g. for DFU/UMS, other two
ports as host)
