This commit introduces the implementation of dm regulator API.
Device tree support allows for auto binding. And by the basic
uclass operations, it allows to driving the devices in a common
way. For detailed informations, please look into the header file.

Core files:
- drivers/power/regulator-uclass.c - provides regulator common functions api
- include/power/regulator.h - define all structures required by the regulator

Changes:
- new uclass-id: UCLASS_REGULATOR
- new config: CONFIG_DM_REGULATOR

At present CONFIG options are split across Kconfig and board config headers
files. Also we have multiple files containing these CONFIG options.

In order to see exactly what is being used for building, create a .cfg
file which holds these options as reported by the C preprocessor.

With sandbox we want to be able to emulate USB devices so that we can test
the USB stack. Add a uclass to support this. It implements the same
operations as a normal USB device driver, but in this case passes them on
to an emulation driver.

Work_92105 from Work Microwave is an LPC3250-
based board with the following features:
- 64MB or 128MB SDR DRAM
- 1 GB SLC NAND, managed through MLC controller.
- Ethernet
- Ethernet + PHY SMSC8710
- I2C:
  - EEPROM (24M01-compatible)
  - RTC (DS1374-compatible)
  - Temperature sensor (DS620)
  - DACs (2 x MAX518)
- SPI (through SSP interface)
  - Port expander MAX6957
- LCD display (HD44780-compatible), controlled
  through the port expander and DACs

This board has SPL support, and uses the LPC32XX boot
image format.

Since the Kconfig conversion, config.mk has been included only when
include/config/auto.conf is newer than the .config file.

It causes build error if both files have the same time-stamps.
It is actually possible because EXT* file systems have a 1s time-stamp
resolution.

The config.mk should be included when include/config/auto.conf is
*not older* than the .config file.

We have switched to the single .config configuration system,
the same one as used in Linux Kernel.

The necessary glue code is small enough now, so move it to the
top-level Makefile and scripts/kconfig/Makefile, and then delete

Commit a93648d1 introduced linker generated
lists for imagetool which is the base for some host tools (mkimage, dumpimage,
et al.).  Unfortunately some host tool chains do not support the used type of
linker scripts. Therefore this commit broke these host-tools for them, namely
FreeBSD and Darwin (OS/X).

This commit tries to fix this. In order to have a clean distinction between host
and embedded code space we need to introduce our own linker generated list
instead of re-using the available linker_lists.h provided functionality.  So we
copy the implementation used in linux kernel script/mod/file2alias.c which has
the very same problem (cause it is a host tool). This code also comes with an
abstraction for Mach-O binary format used in Darwin systems.

We cannot do this by default since it requires binary blobs. Without these

For boards which use multiple I2C devices, or for SOCs which support
multiple boards, we might want to convert these to driver model at different
times. At present this is difficult because we need to either use
CONFIG_DM_I2C for a board or not.

Add a compatibility layer which implements the old API, thus allowing a
board to move to driver model for I2C without requiring that everything it
uses is moved in the same commit.

Introduce a Makefile under arch/$ARCH/ and include it in the
top Makefile (similar to Linux kernel). This allows further
refactoringi like moving architecture-specific code out of global
makefiles, deprecating config variables (CPU, CPUDIR, SOC) or
deprecating arch/$ARCH/config.mk.

In contrary to Linux kernel, U-Boot defines the ARCH variable by
Kconfig, thus the arch Makefile can only included conditionally
after the top config.mk.

On x86 machines U-Boot needs to be added to a large ROM image which is
then flashed onto the target board. The ROM has a particular format so it
makes sense for U-Boot to build this image automatically. Unfortunately
it relies on binary blobs so we cannot require this for the default
build as yet.

Create a u-boot.rom output file for this purpose.

Since Linux 3.15, relative path feature and related fixes,

[6] commit 3f1d9a6cec01 by Michal Marek
