Adjust the sandbox serial driver to use the new driver model uclass. The
driver works much as before, but within the new framework.

Serial devices support simple byte input/output and a few operations to find
out whether data is available. Add a basic uclass for serial devices to be
used by drivers that are converted to driver model.

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.

Commit fa9c021632473 ("mx6: add example DTB for mx6qsabreauto") introduced
'imx6q-sabreauto.dts' but it adds no real value as the dts file only contains
the 'model' and 'compatible' strings.
After this commit the final binary is also changed from 'u-boot.imx' to
'u-boot-dtb.imx', which may confuse users.
So revert it until a more complete and useful device tree could be provided.

the Tx stops functioning after a fair amount of Tx traffic

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.

For LS102xA, the processor is in little-endian mode, while esdhc IP is
in big-endian mode. CONFIG_SYS_FSL_ESDHC_LE and CONFIG_SYS_FSL_ESDHC_BE

endian mode.

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.

Previously, we used to statically assign values for vl_col, vl_row and
vl_bpix using #defines like LCD_XRES, LCD_YRES and LCD_COLOR16.
Introducing the function exynos_lcd_early_init() would take care of this
assignment on the fly by parsing FIMD DT properties, thereby allowing us
to remove LCD_XRES and LCD_YRES from the main config file.

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.

- set_dfu_alt_info() - put dfu system and bootloader setting
into $dfu_alt_info.
functions declaration:
- char *get_dfu_alt_system(void)
- char *get_dfu_alt_boot(void)
- void set_dfu_alt_info(void)

- CONFIG_SET_DFU_ALT_INFO
This function can be used for auto setting dfu configuration on boot.
Such feature is useful for multi board support by one u-boot binary.
Each board should define two functions:
- get_dfu_alt_system()
- get_dfu_alt_boot()

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

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.
