Add N1213 cpu core (N12 Core family) support for NDS32 arch.
This patch includes start.S for the initialize procedure of N1213.
Start procedure:
start.S will start up the N1213 CPU core at first,
then jump to SoC dependent "lowlevel_init.S" and
"watchdog.S" to configure peripheral devices.

Not draining the FIFO and waiting for the UART to be non-busy
before changing baudrate results in crap characters on the
console, so let's wait for the FIFO to drain and the last
character to be clocked out before we do that.

The examples/api is not configured with USE_PRIVATE_LIBGCC. This makes
building examples/api break on certain boards that do not/cannot use the
public libgcc.
Nevertheless, this patch has to also touch the top-level Makefile to fix
this problem because the current top-level Makefile does not specify
libgcc as a prerequisite of examples/api, and explicitly builds
examples/api _before_ libgcc.
For testing this patch, I added the following to configs/seaboard.h and
ran demo.bin on a Seaboard.
+#define CONFIG_API
+#define CONFIG_SYS_MMC_MAX_DEVICE 2
+#define CONFIG_CMD_NET
+#define CONFIG_NET_MULTI

This patch move the reset function from initialization to
driver register procedure.
Some embedded system supports wake on lan nowadays. On this kind of system,
the ftgmac100 will be still supplied power after the system has been
shut-down by Linux. Hence the register used by linux won't be clear
when the system has been powered-off.
The origin ftgmac100 driver in u-boot will only register
driver and functions to network stack and won't reset the ftgmac100
hardware if the network won't be used during boot-up.
This will lead ftgmac100 continue receiving packets and then might corrupt
linux kernel when booting up.
So we reorder the hardware reset function earlier to force the hardware
to be reset whether it will be used or not.

To ease the implementation of other MPC85xx board ports, several common
GPIO helpers are added to <asm/mpc85xx_gpio.h>.
Since each of these compiles to no more than 4-5 instructions it would
be very inefficient to call them out of line, therefore we put them
entirely in the header file.
The HWW-1U-1A board port which these were written for strongly prefers
to set multiple GPIOs as a single batch operation, so the API is
designed around that basis.
To assist other board ports, a small set of wrappers are used which
provides a standard gpio_request() interface around the MPC85xx-specific
functions. This can be enabled with CONFIG_MPC85XX_GENERIC_GPIO

Commit 4750884 introduced a change in the dependency generation which
breaks SPL, because the source files being built are not initially present
and are symlinked as part of the build.
The .depend file must depend not only on the files in the DEPS list but
also on the sources which did not contribute files to the DEPS list, since
these sources will otherwise not get a dependency and will not be built.

Add common function fdt_set_node_status() to assist in various locations
that we set a nodes status. This function utilizes the status values
that are part of the EPAPR spec (on power.org).
fdt_set_status_by_alias() is based on fdt_set_node_status() but uses an
alias string to identify the node to update.
We also add some shortcut functions to help the common cases of setting
"okay" and "disabled":
fdt_status_okay()
fdt_status_disabled()
fdt_status_okay_by_alias()
fdt_status_disabled_by_alias()
Finally, we fixup the corenet_ds ethernet code which previously had
a function by the same name that can be replaced with the new helpers.

There is a rather subtle build problem where the build time stamp is not
updated for out-of-tree builds if there exists an in-tree build which
has a valid timestamp file. So if you do an in-tree build, then an
out-of-tree build your timestamp will not change.
The correct timestamp_autogenerated.h lives in the object tree, but it
is not always found there. The source still lives in the source tree and
when compiling version.h, it includes timestamp_autogenerated.h. Since
the current directory is always searched first, this will come from the
source tree rather than the object tree if it exists there. This affects
dependency generation also, which means that common/cmd_version.o will not
even be rebuilt if you have ever done an in-tree build.
A similar problem exists with the version file.
This change moves both files into the 'generated' subdir, which is already
used for asm-offsets.h. Then timestamp.h and version.h are updated to
include the files from there.
There are other places where these generated files are included, but I
cannot see why these don't just use the timestamp.h and version.h headers.
So this change also tidies that up.
I have tested this with in- and out-of-tree builds, but not SPL. I have
looked at various other options for fixing this, including sed on the dep
files, -I- and -include flags to gcc, but I don't think they can be made
to work. Comments welcome.

At this point U-Boot will build and run on x86 under Linux.
The idea is to define a new architecture called 'sandbox', alongside ARM
and x86. This runs natively on Linux to suit the host machine. All
hardware access is either omitted or emulated.
The purpose of this system is to test the bulk of the non-hardware-specific
U-Boot code. We can mock the SPI flash, GPIOs, UART and keyboard, then test
that U-Boot behaves as we wish.

The dependency rules are currently done in a shell 'for' loop. This does not
permit Makefile variables to adjust preprocessor flags as is done with normal
compile flags, using the CFLAGS_path/file.o syntax.
This change moves the dependency generation into the Makefile itself, and
permits a CPPFLAGS_path/file.o to adjust preprocessor flags on a file or
directory basis.
The CPPFLAGS_... variable is also folded into CFLAGS during the build.
