Masahiro Yamada 237c36379c ARM: tegra: move NVIDIA common files to arch/arm/mach-tegra
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.

boards that support CONFIG_ARMV7_NONSEC, and it only works on those.

Arun Bharadwaj 2a3c25d242 overo: Fix regression introduced in a6b541b
U-Boot has been broken on Overo boards since commit
a6b541b090.

This is because the gd pointer is not set early enough anymore,
such that the i2c_set_bus_num in get_board_revision can safely
execute. This results in a console hang at SPL and the boot does
not proceed.

This piece of code is anyway necessary only for really old Overo
boards with revision numbers <= 2410 and not required for the newer
boards. For these older boards, u-boot v2014.10 still works fine.

Hannes Petermaier 99f7247211 board/BuR/tseries: Add simplefb support
Since the used AM3352 SoC doesn't have GPU it isn't allways necessary to build
in complete drm-stuff into linux kernel. In very small applications only we use
the simple-framebuffer.

So we have 2 use-cases:
- device operating on drm-driver (let simplefb node disabled)
- device operating on simplefb-driver (activate simplefb node and reserve mem)

The decision is made by means of "simplefb" environment variable.

simplefb = 0
we don't enable the (maybe) existing simplefb node and all the rest around
display is up to the linux-kernel. We just disable the backlight, beceause we
do not want see the flicker during take over of drm-driver.

simplefb = 1
we enable the (maybe) existing simplefb node and reserve framebuffers size
in memory.

Supported peripherals are:

- Ethernet (mvneta)
- I2C
- SPI (including SPI NOR flash)

Please note that this board support right now only supports the
main U-Boot. Without the bin_hdr integration (DDR training etc). This
will be added in a few days / weeks to complete this board port. But
till then this U-Boot version can be run on the target via the
original Marvell U-Boot via this command:

Hans de Goede e13afeef6f sunxi: usb: Do not call phy_probe from hcd code
The 2/3 usb-phys on the sunxi SoCs are really a single separate functional
block, and are modelled as such in devicetree. So once we've moved all the
sunxi usb code to the driver-model then phy_probe will be called once
for the entire block from the driver-model enumeration code.

Move to this now as this also avoids problems with phy_probe being called
multiple times once we introduce ohci support. This also allows us to get rid
of the sunxi_usb_phy_enabled_count variable as phy_probe now is guaranteed
to be called only once.

Since we're effectively rewriting the probe / remove functions, move them
to the end of the file while we are at it, as that is the most logical place
for them.

Hans de Goede 25acd33f85 sunxi: dts: Add a CONFIG_DEFAULT_DEVICE_TREE setting to all sunxi boards
This is a preparation patch for switching all sunxi boards over to using
the driver model.

Note that rather then defining both CONFIG_DEFAULT_DEVICE_TREE (for u-boot)
and CONFIG_FDTFILE (for the kernel), this commit simply replaces all
CONFIG_FDTFILE defconfig settings with CONFIG_DEFAULT_DEVICE_TREE and
uses CONFIG_DEFAULT_DEVICE_TREE for setting the default fdtfile env value
in sunxi-common.h .

Hans de Goede 2fcf033d36 sunxi: axp: Move axp gpio code to a separate axpi-gpio driver
Move the axp-gpio code out of the drivers/power/axp*.c code, and into
a new separate axpi-gpio driver.

This change drops supports for the gpio3 pin on the axp209, as that requires
special handling, and no boards are using it.

Besides cleaning things up by moving the code to a separate driver, as
a bonus this change also adds support for the (non vusb) gpio pins on the
axp221 and the gpio pins on the axp152.

The new axp-gpio driver gets its own Kconfig option, and is only enabled
on boards which need it. Besides that it only gets enabled in the regular
u-boot build and not for the SPL as we never need it in the SPL.

Hans de Goede 4f7e01c961 sunxi: soft-i2c: Fix gpio handling to work with the driver-model
i2c_init_board() gets called before the driver-model (gpio) code is
initialized, so move the setup of the soft-i2c pins out of i2c_init_board()
and into board_init(), at which time the driver-model setup has been done.

Also add proper error checking and properly request the gpios as that is
mandatory with the driver-model.
