d1de41d7fa exynos: Add support for spring
Spring is the first ARM-based HP Chromebook 11. It is similar to snow
and it uses the same Samsung Exynos5250 chip. But has some unusual
features. Mainline support for it has lagged snow (both in kernel and
U-Boot). Now that the exynos5 code is common we can support spring just
by adding a device tree and a few lines of configuration.

c65dc7d874 exynos: Add common board code for exynos5 boards that use device tree
Some boards use device tree for almost all board-specific configuration.
They therefore do not need their own separate board code, but can all use
the same version. Add a common version of the board code. It uses the
PMIC, regulator and video bridge uclasses. This will support smdk5250,
smdk5420, snow, spring, pit and pi.

01acd6abbd usb: USB download gadget and functions config options coherent naming
This introduces a coherent scheme for naming USB download gadget and functions

function's config option is moved to a CONFIG_USB_FUNCTION_ prefix.

2911bd1858 samsung: common: add example boot scripts
This commit adds example scripts of boot.scr:
- bootzimg.cmd - check if dtb exists and boot zImage
- autoboot.cmd - check which image exists: Image.itb, zImage or uImage
                 and optionally load fdt file for u/zImage

The blank spaces are added to improve readability and can be removed
before use mkimage.

Required U-Boot environment variables: $boardname, $fdtfile, $console,
$mmcbootdev, $mmcbootpart, $mmcrootdev, $mmcrootpart, $rootfstype.

Making boot.scr from file.cmd:
 mkimage -C none -A arm -T script -d file.cmd boot.scr

The Odroid XU3 default environment is ready for those boot scripts and
the right script can be loaded by DFU.

58d423b88e dm: select CONFIG_DM* options
As mentioned in the previous commit, adding default values in each
Kconfig causes problems because it does not co-exist with the
"depends on" syntax.  (Please note this is not a bug of Kconfig.)
We should not do so unless we have a special reason.  Actually,
for CONFIG_DM*, we have no good reason to do so.

Generally, CONFIG_DM is not a user-configurable option.  Once we
convert a driver into Driver Model, the board only works with Driver
Model, i.e. CONFIG_DM must be always enabled for that board.
So, using "select DM" is more suitable rather than allowing users to
modify it.  Another good thing is, Kconfig warns unmet dependencies
for "select" syntax, so we easily notice bugs.

Actually, CONFIG_DM and other related options have been added
without consistency: some into arch/*/Kconfig, some into
board/*/Kconfig, and some into configs/*_defconfig.

This commit prefers "select" and cleans up the following issues.

[1] Never use "CONFIG_DM=n" in defconfig files

It is really rare to add "CONFIG_FOO=n" to disable CONFIG options.
It is more common to use "# CONFIG_FOO is not set".  But here, we
do not even have to do it.
Less than half of OMAP3 boards have been converted to Driver Model.
Adding the default values to arch/arm/cpu/armv7/omap3/Kconfig is
weird.  Instead, add "select DM" only to appropriate boards, which
eventually eliminates "CONFIG_DM=n", etc.

[2] Delete redundant CONFIGs

Sandbox sets CONFIG_DM in arch/sandbox/Kconfig and defines it again
in configs/sandbox_defconfig.
Likewise, OMAP3 sets CONFIG_DM arch/arm/cpu/armv7/omap3/Kconfig and
defines it also in omap3_beagle_defconfig and devkit8000_defconfig.

As a side note calls to max77686_set_buck_mode(OPMODE_OFF/OPMODE_ON) have

I looked into the documentation and there is a "ENB8" pin in PMIC package.
This pin allows steering BUCK8 ON/OFF by the hardware. If ENB8 is set to low
then you can do on/off. If high, then you cannot change its state by I2C
write, which seems to be the case with the Odroids.

73186c9460 dm: exynos: Convert SPI to driver model
Move the exynos SPI driver over to driver model. This removes quite a bit
of boilerplate from the driver, although it adds some for driver model.

A few device tree additions are needed to make the SPI flash available.

7f1961018c dm: exynos: Make sure that GPIOs are requested
With driver model GPIOs must be requested before use. Make sure this is
done correctly.

(Note that the soft SPI part of universal is omitted, since this driver
is about to be replaced with a driver-model-aware version)
