Add basic i2c driver for Tegra2 with 8- and 16-bit address support.
The driver requires CONFIG_OF_CONTROL to obtain its configuration
from the device tree.

Some devices can deal with multiple compatible properties. The devices
need to know which nodes to bind to which features. For example an
I2C driver which supports two different controller types will want to
know which type it is dealing with in each case.
The new fdtdec_add_aliases_for_id() function deals with this by allowing
the driver to search for additional compatible nodes for a different ID.
It can then detect the new ones and perform appropriate processing.
Another option considered was to return a tuple (node offset, compat id)
and have the function be passed a list of compatible IDs. This is more
overhead for the common case though. We may add such a function later if
more drivers in U-Boot require it.

This switches Ventana over to use FDT for run-time config instead of
CONFIG options.
At present Ventana does not have its own device tree file - it just uses
the Seaboard one.

CONFIG_OF_CONTROL requires a valid device tree. However, we cannot call
panic() before the console is set up since the message does not appear,
and we get a silent failure.
Remove the panic from fdtdec_check_fdt() and provide a new function to
prepare the fdt for use. This will be called after the console is ready.

This adds basic support for the Tegra2 USB controller. Board files should
call board_usb_init() to set things up.
Configuration is performed through the FDT, with aliases used to set the
order of the ports, like this fragment:
aliases {
/* This defines the order of our USB ports */
usb0 = "/usb@0xc5008000";
usb1 = "/usb@0xc5000000";
};

This adds some support into fdtdec for reading GPIO definitions from
the fdt. We permit up to FDT_GPIO_MAX GPIOs in the system. Each GPIO
is of the form:
gpio-function-name = <phandle gpio_num flags>;
where:
phandle is a pointer to the GPIO node
gpio_num is the number of the GPIO (0 to 223)
flags is a flag, as follows:
bit meaning
0 0=polarity normal, 1=active low (inverted)
An example is:
enable-propounder-gpios = <&gpio 43 0>;
which means that GPIO 43 is used to enable the propounder (setting the
GPIO high), or that you can detect that the propounder is enabled by
checking if the GPIO is high (the fdt does not indicate input/output).
Two main functions are provided:
fdtdec_decode_gpio() reads a GPIO property from an fdt node and decodes it
into a structure.
fdtdec_setup_gpio() sets up the GPIO by calling gpio_request for you.
Both functions can cope with the property being missing, which is taken to
mean that that GPIO function is not available or is not needed.
[For reference, from Stephen Warren <[email protected]>. It may be that
we add this extra complexity later if needed:
The correct way to parse such a GPIO property in general is:
* Read the first cell.
* Find the node referenced by the phandle (the controller).
* Ensure property gpio-controller is present in the controller node.
* Read property #gpio-cells from the controller node.
* Extract #gpio-cells from the original property.
* Keep processing more cells from the original property; there may be
multiple GPIOs listed.
According to the binding documentation in the Linux kernel, Samsung
Exynos4 doesn't use this format, and while all other chips do have a
flags cell, about 50% of the controllers indicate the cell is unused.

Add a function to look up a property which is a phandle in a node, and
another to read a fixed-length integer array from an fdt property.
Also add a function to read boolean properties, although there is no
actual boolean type in U-Boot.

This fixes five trivial issues in fdtdec.c:
1. fdtdec_get_is_enabled() doesn't really need a default value
2. The fdt must be word-aligned, since otherwise it will fail on ARM
3. The compat_names[] array is missing its first element. This is needed
only because the first fdt_compat_id is defined to be invalid.
4. Added a header prototype for fdtdec_next_compatible()
5. Change fdtdec_next_alias() to only increment its 'upto' parameter
on success, to make the display error messages in the caller easier.

Stephen Warren pointed out that we should use nodes whether or not they
have an alias in the /aliases section. The aliases section specifies the
order so far as it can, but is not essential. Operating without alisses
is useful when the enumerated order of nodes does not matter (admittedly
rare in U-Boot).
This is considerably more complex, and it is important to keep this
complexity out of driver code. This patch creates a function
fdtdec_find_aliases() which returns an ordered list of node offsets
for a particular compatible ID, taking account of alias nodes.

This patch adds the support for high speed in usb device framework and usbtty
driver. This feature has been kept within a macro CONFIG_USBD_HS, so the board
configuration files have to define this macro to enable high speed support.
Along with that specific peripheral drivers also need to define a function to
let the framework know that the enumeration has happened at high speed.
This function prototype is "int is_usbd_high_speed(void)"
