Commit 47508843 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.

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.

Since we want want to have a standard GPIO interface, this adds a definition

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.

By default sections are 16-byte aligned on some architectures, but the
command name structure (struct cmd_tbl_s) does not have padding to
16 bytes. This reduces the alignment to 4-bytes so that the command
table can be accessed correctly on any architecture.

(Note: this needs doing properly)
