While looking to upgrade to zlib-1.2.5, the current mondo merge of
multiple files into a single was making things way more difficult
than it should have been.  Hard to pick out what has been changed
to port it to U-Boot, been removed as useless, and bug fixes added
after the fact.

So split the single file up into the original file names, and merge
non-essential changes back from the original tree (for some reason,
style in code in a bunch of places was changed to U-Boot style even
though this isn't "U-Boot" code).

The original build style is retained -- we have a single zlib.c that
includes all the other files, and that is the only file we compile.

Linker needs to use the proper endian/bfd flags even when doing partial linking.
LDFLAGS_u-boot sets linker option which is called it when U-boot is built
(u-boot final).
LDFLAGS sets necessary option by partial linking (use in cmd_link_o_target).

.boards.depend was created in the source tree even when calling make

When building with srctree != objtree, the build creates arch/soc/cpu
specific symlinks in the source tree.  This means that the same source
tree can't be used for multiple builds at the same time.  Also, these
symlinks in the source tree are only cleaned up if one passes the same
O= to distclean.

When srctree != objtree, mkconfig creates an $objtree/include2 directory
in the objtree to host the asm -> arch/$arch/include/asm symlink so that
"#include <asm>" can be used.  But it also creates another identical
symlink in $objtree/include.

Then, mkconfig creates two symlinks:
$objtree/include/asm/arch -> arch/$arch/include/asm/arch-$cpu (or $soc)
$objtree/include/asm/proc -> arch/$arch/include/asm/proc-armv (on arm)
but because $objtree/include/asm points at $srctree already, the two
symlinks are created under $srctree.

To fix this, create a real $objtree/include/asm directory, instead of a
symlink.  Update cleanup code accordingly.

Before this commit, weak symbols were not overridden by non-weak symbols
found in archive libraries when linking with recent versions of
binutils.  As stated in the System V ABI, "the link editor does not
extract archive members to resolve undefined weak symbols".

This commit changes all Makefiles to use partial linking (ld -r) instead
of creating library archives, which forces all symbols to participate in
linking, allowing non-weak symbols to override weak symbols as intended.
This approach is also used by Linux, from which the gmake function
cmd_link_o_target (defined in config.mk and used in all Makefiles) is
inspired.

The name of each former library archive is preserved except for
extensions which change from ".a" to ".o".  This commit updates
references accordingly where needed, in particular in some linker
scripts.

This commit reveals board configurations that exclude some features but
include source files that depend these disabled features in the build,
resulting in undefined symbols.  Known such cases include:
- disabling CMD_NET but not CMD_NFS;
- enabling CONFIG_OF_LIBFDT but not CONFIG_QE.

For ARM systems, before ELF relocation was introduced,
CONFIG_SKIP_RELOCATE_UBOOT coul be used to prevent *COPYING* the
U-Boot image from whereever it was loaded to it's link address
(CONFIG_SYS_TEXT_BASE).  The name was badly chosen, as no relocation
was performed at all, it was just a memcpy().

With ELF relocation, this does not work like that any more, and
related boards need to be fixed anyway.  So don't keep this relict any
longer.

After moving the definition of CONFIG_SYS_TEXT_BASE to the respective
board config files, all Marvell kirkwood board have just a single and
common entry in their config.mk files:

	KWD_CONFIG = $(SRCTREE)/board/$(BOARDDIR)/kwbimage.cfg

Replace the only reference to KWD_CONFIG in the top level Makefile by
an equivalent setting, and remove all kirkwood config.mk files.

A recurrent issue is that certain C level constructs like sizeof() or
offsetof() cannot be used in assembler files, which is inconvenient
when such constructs are used in the definition of macro names etc.

To avoid duplication of such definitions (and thus another cause of
problems), we adapt the Linux way to automatically generate the
respective definitions from the respective C header files.

In Linux, this is implemented in include/linux/kbuild.h, Kbuild, and
arch/*/kernel/asm-offsets.c; we adapt the code from the Linux v2.6.36
kernel tree.

We also copy the concept of the include/generated/ directory which can
be used to hold other automatically generated files as well.

We start with an architecture-independent lib/asm-offsets.c which
generates include/generated/generic-asm-offsets.h (included by
include/asm-offsets.h, which is what will be referred to in the actual
source code).  Later this may be extended by architecture-specific
arch/*/lib/asm-offsets.c files that will generate a
include/generated/asm-offsets.h.

Boards often have a reserved size limit on the flash where they're stored.
Sometimes during upgrades or config changes, those limits are exceeded,
but no one notices until they try to upgrade and the limit screws things
up.  Either not enough of U-Boot is written to flash (and so the reboot
fails), or too much is written (and so things after it get clobbered).

So allow boards to declare a size limit (in bytes) and have the build
system check it while building.
