This patch imports i2c_smbus_{read,write}* functions from linux-3.15.
Here is a quote from linux.git/Documentation/i2c/smbus-protocol:
If you write a driver for some I2C device, please try to use the SMBus
commands if at all possible (if the device uses only that subset of the
I2C protocol). This makes it possible to use the device driver on both
SMBus adapters and I2C adapters (the SMBus command set is automatically
translated to I2C on I2C adapters, but plain I2C commands can not be
handled at all on most pure SMBus adapters).
So having i2c_smbus_{read,write}* functions in barebox makes
porting of linux i2c client drivers much easier as many drivers rely on
these smbus functions.

This patch does probably too much, but it's hard (and very
cumbersome/time consuming) to break it out. What is does is this:
* each command has one short description, e.g. "list MUX configuration"
* made sure the short descriptions start lowercase
* each command has one usage. That string contains just the
options, e.g. "[-npn]". It's not part of the long help text.
* that is, it doesn't say "[OPTIONS]" anymore, every usable option
is listed by character in this (short) option string (the long
description is in the long help text, as before)
* help texts have been reworked, to make them
- sometimes smaller
- sometimes describe the options better
- more often present themselves in a nicer format
* all long help texts are now created with BUSYBOX_CMD_HELP_
macros, no more 'static const __maybe_unused char cmd_foobar_help[]'
* made sure the long help texts starts uppercase
* because cmdtp->name and cmdtp->opts together provide the new usage,
all "Usage: foobar" texts have been removed from the long help texts
* BUSYBOX_CMD_HELP_TEXT() provides the trailing newline by itself, this
is nicer in the source code
* BUSYBOX_CMD_HELP_OPT() provides the trailing newline by itself
* made sure no line gets longer than 77 characters
* delibertely renamed cmdtp->usage, so that we can get compile-time
errors (e.g. in out-of-tree modules that use register_command()
* the 'help' command can now always emit the usage, even without
compiled long help texts
* 'help -v' gives a list of commands with their short description, this
is similar like the old "help" command before my patchset
* 'help -a' gives out help of all commands

Linux specifies the linux,stdout-path property in the /chosen node

For cases in which barebox uses this property for its own use we
translate this into a Linux boot arg with:
- the console name provided by the serial driver
- the the instance from the 'serial' alias
- the baudrate from the actual baudrate.
So with this it's for devicetee enabled boards no longer necessary
to manually assign a console= parameter. Should a user not want
to use the automatically assigned parameter it should do:
global.linux.bootargs.console=
in the environment.

The eMMC and the SD-Card specifications describe the optional SET_DSR command.
During measurements at our lab we found that some cards implementing this feature
having really strong driver strengts per default. This can lead to voltage peaks
above the specification of the host on signal edges for data sent from a card to
the host.
Since availability of a given card type may be shorter than the time a certain
hardware will be produced it is useful to have support for this command (Alternative
would be changing termination resistors and adapting the driver strength of the
host to the used card.)

eMMC is available up to version 4.5 but the
correct version is not decoded. Change version
definitions to support more minor verions, add
missing versions and parse the minor versions from
ext_csd.
After this, card detection code and devinfo reports
correct versions.
Handling is inspired by u-boot code.

The common bootm code used to load uImage contents to SDRAM
before calling into the handlers if possible. This makes the
handlers complicated since they have to handle many cases. Instead,
introduce a helper to load the os after the handlers have figured
out a good load address.

ubiformat needs the subpagesize to work correctly. The kernel uses
sysfs to pass the subpagesize, but in barebox we have the possibility
to extend struct mtd_info_user. Add a corresponding field and use it
in ubiformat.

Sometimes execution of a function has to be delayed, for example
when a backlight can only be turned on when the picture has stabilized.
To help in such situations add a convenience function around the poller
stuff to call a function after a delay.

With this phy_device_connect only registers a phy device if it wasn't
registered already. This allows us to register phy devices outside
of ethernet drivers. phy_device_connect will now pick up an already
registered phy given that it's not attached to another ethernet device.

If an ethernet device already has a phy in phy_device_connect all we
have to do is to start autonegotiation. Do this early and bail out
so that for the rest of the code it's clear that we have to search for
a phy device.

We currently have functions to add a device based on function parameters.
This adds the corresponding functions to add resources to a device without
registering the device itself. This is useful to manipulate devices before
registering them.

Instead of requiring a device pointer, add a functions to select
the pinctrl state based on a device node.
The AM33xx cpsw devicetree description has several subdevices with
pinctrl information attached to them. In barebox we do not handle
the subdevices as distinct devices, so the pinctrl is never configured
correctly and the mdio bus subdevice stops working. This patch makes
it possible to configure the pinctrl without having a device.

gpiolib: use descriptors internally
Make sure gpiolib works internally with descriptors and (chip, offset)
pairs instead of using the global integer namespace. This prepares the
ground for the removal of the global gpio_desc[] array and the
introduction of the descriptor-based GPIO API.

The current implementation of the bootloader specification depends on the
hardware name and the name of the device in /dev to match. As the default
hardware name is mciX and the device name is diskY the bootloader spec
cannot be used as is.
This patch implements a way to overwrite the device name similar to what is
possible for the imx-esdhc driver.
