update to provide usable implementation to U-Boot
Signed-off-by: NSteve Rae <srae@broadcom.com>

U-Boot has imported various source files from other projects,
mostly Linux.

Something like

  #ifdef __UBOOT__
    [ modification for U-Boot ]
  #else
    [ original code ]
  #endif

is an often used strategy for clarification of adjusted parts,
that is, easier re-sync in future.

Instead of defining __UBOOT__ in each source file,
passing it from the top Makefile would be easier.

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.
Signed-off-by: NSimon Glass <sjg@chromium.org>

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 full serial port nodes from Linux tree (commit fc9d4dbe)

Add driver model support so that ns16550 can support operation both with

The driver needs a clock frequency so cannot stand alone unfortunately. The
clock frequency must be provided by a separate driver.

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.

Allocate 1KB so that driver model can operate before relocation.

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.

JEDEC spec allows DRAM vendors to use prime DQ for write leveling. This
is not an issue unless some DQ pins are not connected. If a platform uses
regular DIMMs but with reduced DDR ECC pins, the prime DQ may end up on
those floating pins for the second rank. The workaround is to use a known
good chip select for this purpose.

fsl_enet.h defines the mapping of the usual MII management
registers, which are included in the MDIO register block
common to Freescale ethernet controllers. So it shouldn't
depend on the CPU architecture but it should be actually
part of the arch independent fsl_mdio.h.

To remove the arch dependency, merge the content of
asm/fsl_enet.h into fsl_mdio.h.
Some files (like fm_eth.h) were simply including fsl_enet.h
only for phy.h. These were updated to include phy.h instead.

On an Odroid U3 board, the SOC is unable to reset the eMMC card
in the DWMMC mode by the cpu software reset. Manual reset of the card
by switching proper gpio pin - fixes this issue.

Such solution needs to add a call to pre reset function.
This is done by the reset_misc() function, which is called before reset_cpu().
The function reset_misc() is a weak function.

This commit provides distinction between DFU device detach and reset.
The -R behavior is preserved with proper handling of the dfu-util's -e
switch, which detach the DFU device.

By running dfu-util -e; one can force device to finish the execution of
dfu command on target and execute some other scripted commands.

Moreover, some naming has been changed - the dfu_reset() method now is known
as dfu_detach(). New name better reflects the purpose of the code.

It was also necessary to increase the number of usb_gadget_handle_interrupts()
calls since we also must wait for detection of the USB reset event.

Example usage:
1. -e (detach) switch
 dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e

 access to u-boot prompt.

2. -R (reset) switch

The GPIO list is very long in many cases and most of them are not used.
By default, show only the GPIOs that are in use, and provide a flag to show
all of them. This makes the 'gpio status' command much more pleasant.

In order to do this, driver model now exposes a method for obtaining the
'function' of a GPIO, which describes whether it is an input or output, for
example. Implementation of this method is optional.
