This option refers only to the tegra20 video driver, so name it as such
to avoid confusion with tegra124.
Also move this option to Kconfig.

Make sure SODIMM pin 87 nRESET_OUT is released properly by explicitly
setting its pin mux function to GMI. This solves some issues with e.g.
USB not being fully operational on carrier boards with USB hubs
connected to reset if U-Boot got loaded via recovery mode aka rcm.

Various clean-ups either in comments, order or spacing without any
functional impact:
- Add some comments in the device trees resp. reorder some parameters
for consistency across all our modules.
- Sort some include files alphabetically (while leaving common.h on
top of course).
- Streamline some comments in the configuration files and fix the
spacing from using spaces to tabs.

The Colibri T20's PMIC enters a sleep mode on low supply voltage < 3.0V
±2.5% (2.92...3.08V). Rising the main supply voltage again does not
bring it back to regular operation. Not even a full reset does bring
the module back. A full power cycle was required to reboot the system.
A long positive pulse on the PMICs resume pin also reboots the system
but this pin is only accessible as a test point on the module.
This patch configures the PMIC through I2C to not enter this sleep mode
plus force it to normal state upon sleep request exit should this ever
happen.

Add IOMUX for the pad used as USB pen. This needs to be driven low for
the Iris and Viola boards where it is pulled up high by default. This is
required for the USB host functionality to work on these boards. Use the

would be called on "usb start".

All the Tegra boards borrow the files from board/nvidia/common/
directory, i.e., board/nvidia/common/* are not vendor-common files,
but SoC-common files.
Move NVIDIA common files to arch/arm/mach-tegra/ to clean up
Makefiles.
As arch/arm/mach-tegra/board.c already exists, this commit renames
board/nvidia/common/board.c to arch/arm/mach-tegra/board2.c,
expecting they will be consolidated as a second step.

This adds initial support for Colibri VF50/VF61 based on Freescale
Vybrid SoC.
- CPU clocked at 396/500 MHz
- DDR3 at 396MHz
- for VF50, use PLL2 as memory clock (synchronous mode)
- for VF61, use PLL1 as memory clock (asynchronous mode)
- Console on UART0 (Colibri UART_A)
- Ethernet on FEC1
- PLL5 based RMII clocking (E.g. No external crystal)
- UART_A and UART_C I/O muxing
- Boot from NAND by default
Tested on Colibri VF50/VF61 booting using serial loader over UART.

Rather than assuming that the chip offset length is 1, allow it to be

Add a dm_ prefix to driver model I2C functions so that we can keep the old
ones around.

This converts all Tegra boards over to use driver model for I2C. The driver
is adjusted to use driver model and the following obsolete CONFIGs are

- CONFIG_SYS_I2C_INIT_BOARD
- CONFIG_I2C_MULTI_BUS
- CONFIG_SYS_MAX_I2C_BUS
- CONFIG_SYS_I2C_SPEED
- CONFIG_SYS_I2C
This has been tested on:
- trimslice (no I2C)
- beaver
- Jetson-TK1
It has not been tested on Tegra 114 as I don't have that board.

CPU_ARM1176, CPU_V7, CPU_PXA, CPU_SA1100.
Also, it adds the CPU feature Kconfig symbol HAS_VBAR which is selected
for CPU_ARM1176 and CPU_V7.
For each target, the corresponding CPU is selected and the definition of
SYS_CPU in the corresponding Kconfig file is removed.
Also, it removes redundant "string" type in some Kconfig files.

This patch adds board support for the Toradex Apalis T30 a computer on
module which can be used on different carrier boards.
For the sake of ease of use we do not distinguish between different
carrier boards for now as the base module features are deemed
sufficient enough for regular booting.
The following functionality is working so far:
- eMMC boot and environment storage
- Gigabit Ethernet (once Thierry's PCIe as well as my E1000 resp. i210
fixes hit mainline)
- MMC/SD cards (both 8-bit as well as 4-bit slot)
- USB client/host (dual role port as client e.g. for DFU/UMS, other two
ports as host)

We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.
The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.
After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.
TODO:
Modify get_maintainer.pl to scan multiple MAINTAINERS files.

This commit adds:
- arch/${ARCH}/Kconfig
provide a menu to select target boards
- board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
set CONFIG macros to the appropriate values for each board
- configs/${TARGET_BOARD}_defconfig
default setting of each board
(This commit was automatically generated by a conversion script
based on boards.cfg)
In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.
But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

Unlike Linux Kernel, U-Boot historically had *.dts files under
board/$(VENDOR)/dts/ and *.dtsi files under arch/$(ARCH)/dts/.
I think arch/$(ARCH)/dts dicretory is a better location
to store both *.dts and *.dtsi files.
For example, before this commit, board/xilinx/dts directory
had both Microblaze dts (microblaze-generic.dts) and
ARM dts (zynq-*.dts), which are totally unrelated.
This commit moves *.dts to arch/$(ARCH)/dts/ directories,
allowing us to describe nicely mutiple DTBs generation in the next commit.
