2979b26323 autoconfig.mk: Make it possible to define configs from other configs
Give more flexibility to define configs that can be interpreted by make, e.g. to
define fallback values of configs like in the example below.

Before this change, the config lines:
 #define CONFIG_SPL_MAX_SIZE	2048
 #define CONFIG_SPL_PAD_TO	CONFIG_SPL_MAX_SIZE
would have been changed in autoconfig.mk into:
 CONFIG_SPL_MAX_SIZE=2048
 CONFIG_SPL_PAD_TO="CONFIG_SPL_MAX_SIZE"

Hence, a make recipe using as an argument to $(OBJCOPY):
 --pad-to=$(CONFIG_SPL_PAD_TO)
would have issued:
 --pad-to="CONFIG_SPL_MAX_SIZE"
which means nothing for $(OBJCOPY) and makes it fail.

Thanks to this change, the config lines above are changed in autoconfig.mk into:
 CONFIG_SPL_MAX_SIZE=2048
 CONFIG_SPL_PAD_TO=$(CONFIG_SPL_MAX_SIZE)

Hence, the make recipe above now issues:
 --pad-to=2048
as expected from the defined config.

e4691f5ed1 make-asm-offsets: fix sed script
When copying the "sed" script to generate the asm-offsets.h file from
the Linux Kbuild script into the make-asm-offsets file I missed the
fact that the former runs in a "make" context and thus uses double
"$$" to escape a single "$", while the latter is a shell script, where
this must not be done.  Unfortunately the problem did not show up
during the initial tests on Power Architecture systems, but on ARM the
generated asm-offsets.h was not correct.

16a354f920 include/asm-offsets.h: automatically generate assembler constants
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.

2bad5df727 autoconfig.mk: avoid apostophes around hex values
When generating include/autoconfig.mk, hex numbers would be quoted.
This caused some false positives during automatic testing of the
builds, and is known to cause some real issues for some Blackfin
configurations. Don't use apostophes for decimal and hex numbers (nor
for octal numbers).

02409f8cf5 make define2mk.sed work on FreeBSD
In the thread "[1.3.2-rc1] MPC8548CDS/MPC8555CDS configs fails to link",
the define2mk.sed script was identified as the source of the link
failure on FreeBSD. The problem is that sed(1) does not always support
the '+' operator. It isn't on FreeBSD. The attach patch implements the
equivalent, using the '*' operator instead and should work everywhere.

2f155f6c0a [BUILD] Generate include/autoconf.mk from board config files
Use cpp and sed to postprocess config.h and import the defined values
into include/autoconf.mk.  autoconf.mk is then included by config.mk to
give 'make' access to the board configuration.

Doing this enables conditional compilation at the Makefile level instead
of by wrapping every .c file with #ifdef/#endif wrappers.
