c0d57304eb sandbox: Use defconfig to enable features
Stop using the sandbox arch Kconfig to override defaults for config
options. This is a bit of abuse and may be causing build problems.

9038cd5313 sandbox: dts: add sandbox_pmic.dtsi and include it to sandbox.dts and test.dts
This commit adds dtsi file for Sandbox PMIC.
It fully describes the PMIC by:
- i2c emul node - with a default settings of 16 registers
- 2x buck regulator nodes
- 2x ldo regulator nodes

The default register settings are set with preprocessor macros:
- VAL2REG(min[uV/uA], step[uV/uA], val[uV/uA])
- VAL2OMREG(mode id)
Both defined in file:
- include/dt-bindings/pmic/sandbox_pmic.h

The Voltage ranges of each regulator can be found in:
- include/power/sandbox_pmic.h

The new file is included into:
- sandbox.dts
- test.dts

f64000c302 test: dm: test.dts - move to sandbox dts directory
The file test.dts from driver model test directory,
was compiled by call dtc in script: test/dm/test-dm.sh.

This doesn't allow for including of dtsi files and using
of C preprocessor routines in this dts file.

Since the mentioned script builds U-Boot before tests,
then moving the test.dts file into sandbox dts directory
is reasonable.

ebaa832e99 sandbox: Don't try distro_bootcmd by default
For the distro_bootcmds to succeed on the sandbox a bit of setup is

Add a -b/--boot command to the sandbox binary, which triggers the
distro_bootcmds to run after the other command-line commands.

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.

3fbb78711c cros_ec: exynos: Match up device tree with kernel version
The U-Boot device trees are slightly different in a few places. Adjust them
to remove most of the differences. Note that U-Boot does not support the
concept of interrupts as distinct from GPIOs, so this difference remains.

For sandbox, use the same keyboard file as for ARM boards and drop the
host emulation bus which seems redundant.

22f68524f8 sandbox: eth: Add support for using the 'lo' interface
The 'lo' interface on Linux doesn't support thinks like ARP or
link-layer access like we use to talk to a normal network interface.
A higher-level network API must be used to access localhost.

As written, this interface is limited to not supporting ICMP since the
API doesn't allow the socket to be opened for all IP traffic and be able
to receive at the same time. UDP is far more useful to test with, so it
was selected over ICMP. Ping won't work, but things like TFTP should
work.
