Since the CS of a device connected to the GPMC was
stored in the global variable, it was not possible to
use multiple devices. In this patch the CS is stored per
device in its 'struct omap_nand_info'. This makes it
possible to use up to 'GPMC_MAX_CS' NAND Flash devices
connected to U-boot.

This allows the USB code to determine whether a USB bus reset was issued,
which in turn allows the code to differentiate between a detach (return
to shell prompt) and a board reset/reboot request.

New dfu_usb_get_reset() method is necessary to distinct two different
use cases of dfu-util program.
This method checks if the USB bus reset has been really performed after
DFU DETACH.

Without this function the previous DFU behavior is preserved.

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
 dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage

 target board reset

Add a bank of GPIOs for sandbox which can be used for testing this

The gpio command mostly relies on gpio_request() and gpio_free() being
nops, in that you can request a GPIO twice. With driver model this is
now implemented correctly, so it fails.

Change the command to deal with a failure to claim the GPIO.

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

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.

The QS Systems TQMa6 board support was added by commit cb07d74e
and lost by commit e82abaeb.

Commit e82abaeb merged the IMX branch based on pre-Kconfig
and the mainline based on post-Kconfig, simply deleting
the boards.cfg file.  As a result, some boards added just before
the merge were lost.

This commit adds Kconfig, defconfig, MAINTAINERS for TQMa6 board
to work on the Kconfig infrastructure.
