U-Boot does not have arch/arm/kernel, include/uapi directories,
This commit copies files as follows:
Location in Linux -> Location in U-Boot
arch/arm/kernel/debug.S -> arch/arm/lib/debug.S
arch/arm/include/debug/8250.S -> arch/arm/include/debug/8250.S
include/uapi/linux/serial_reg.h -> include/linux/serial_reg.h

The private libgcc is supported only on ARM, MIPS, PowerPC, SH, x86.
Those architectures should "select" HAVE_PRIVATE_LIBGCC and
CONFIG_USE_PRIVATE_LIBGCC should depend on it.
Currently, this option is enabled on Tegra boards and x86 architecture.
Move the definition from header files to Kconfig.

CONFIG_SYS_HZ is always defined as 1000 in config_fallbacks.h
(but some boards still have redundant definitions).
This commit moves the definition and the document in README to
Kconfig. Since lib/Kconfig can assure that CONFIG_SYS_HZ is 1000,
the sanity check in lib/time.c should be removed.

The Marvell MV78460 eval board DB-78460-BP seems to need a longer
PHY autonegotiation timeout than the "standard" 4 seconds. So lets
make this timeout configurable. If not defined in the board config
header the original 4000ms is used.

XP SoC
This patch adds support for the NETA ethernet controller which is integrated
in the Marvell Armada XP SoC's. This port is based on the Linux driver which
has been stripped of the in U-Boot unused portions.
Tested on the Marvell MV78460 eval board db-78460-bp.

These mbus functions are ported from Barebox. The Barebox version is

these functions as well (Kirkwood, Orion).

To get a display in U-Boot on link you must either build a coreboot that
always sets it up, or use Esc-Refresh-Power to reset the machine.
When we do have a display, it is nice to display the model at the top, so

We may as well use hush. The auto-complete option was incorrect so this was

Adjust the driver so that leaf functions take a pointer to the serial port
register base. Put all the global configuration in the init function, and
use the same settings from then on.
This makes it much easier to move to driver model without duplicating the
code, since with driver model we use platform data rather than global
settings.
The driver is compiled with either the CONFIG_PL010_SERIAL or
CONFIG_PL011_SERIAL option and this determines the uart type. With driver
model this needs to come in from platform data, so create a new
CONFIG_PL01X_SERIAL config which brings in the driver, and adjust the
driver to support both peripheral variants.

This feature provides for init of a single SPI port for the soft SPI
feature. It is not really compatible with driver model since it assumes a
single SPI port. Also, inserting SPI init into the driver by means of
a #define is not very nice.
This feature is not used by any active boards, so let's remove it.

U-Boot includes a SPI emulation driver already but it is not explicit, and
is hidden in the SPI flash code.
Conceptually with sandbox's SPI implementation we have a layer which
creates SPI bus transitions and a layer which interprets them, currently
only for SPI flash. The latter is actually an emulation, and it should be
possible to add more than one emulation - not just SPI flash.
Add a SPI emulation uclass so that other emulations can be plugged in to
support different types of emulated devices on difference buses/chip
selects.

Add a uclass which provides access to SPI buses and includes operations
required by SPI.
For a time driver model will need to co-exist with the legacy SPI interface
so some parts of the header file are changed depending on which is in use.
The exports are adjusted also since some functions are not available with
driver model.
