Use driver model for serial ports.
Since Tegra now uses driver model for serial, adjust the definition of
V_NS16550_CLK so that it is clear that this is only used for SPL.

Some Tegra device tree files do not include information about the serial
ports. Add this and also add information about the input clock speed.
The console alias needs to be set up to indicate which port is used for
the console.
Also add a binding file since this is missing.

Add driver model support so that ns16550 can support operation both with
and without driver model.
The driver needs a clock frequency so cannot stand alone unfortunately. The
clock frequency must be provided by a separate driver.

If the sandbox device tree is provided to U-Boot (with the -d flag) then it

The current sandbox serial driver is a pretty trivial example and does not
have the featues that might be needed for other board serial drivers. To
help provide a better example, add a text colour property to the device
tree for sandbox. This uses platform data, a device tree node, driver
private data and a remove() method.

This is an implementation of GPIOs for Tegra that uses driver model. It has
been tested on trimslice and also using the new iotrace feature.
The implementation uses a top-level GPIO device (which has no actual GPIOS).
Under this all the banks are created as separate GPIO devices.
The GPIOs are named as per the Tegra datasheet/header files: A0..A7, B0..B7,
..., Z0..Z7, AA0..AA7, etc.
Since driver model is not yet available before relocation, or in SPL, a
special function is provided for seaboard's SPL code.

For some boards board_init() will change GPIOs, so we need to have driver
model available before then. Adjust the board init to arrange this, but
enable it for driver model only, just to be safe.
This does create additional #ifdef logic, but it is safer than trying to
make a pervasive change which may cause some boards to break.
Signed-off-by: Simon Glass <sjg@chromium.org>
Since driver model registers itself with the stdio subsystem, and we
want to avoid delayed registration and other complexity associated with
the current serial console, move the stdio subsystem init earlier when
driver model is used for serial.
This simplifies the implementation. Should there be any problems with
this approach they can be dealt with as boards are converted over to
use driver model for serial.
Signed-off-by: Simon Glass <sjg@chromium.org>
In order to support GPIO access in board_early_init_f() we must set up
driver model before this function is called. In any case, earlier is
better since driver model is (or will become) a key function for most
init.

For an occasional user of patman some failures are not obvious: for
instance when checkpatch reports warnings, the dry run still reports

When a build is to be performed, buildman checks to see if it has already
been done. In most cases it will not bother trying again. However, it was
not reading the return code from the 'done' file, so if the result was a
failure, it would not be counted. This depresses the 'failure' count stats
that buildman prints in this case.
Fix this bug by always reading the return code.
