[U-Boot-Users] [PATCH 0/2] Enable Makefile conditional compilation

These 2 patches enable conditional compilation at the Makefile level in u-boot. Using this we can finally start getting rid of the #ifdef/#endif wrappers around every .c file.
Wolfgang, I've also pushed this to the 5xxx git tree (see below). This change is much easier to merge, but is far more risky (because it's the first one). If we're doing a short cycle just for build changes, then this is probably the best time to do it.
I've tested with MAKEALL and verified image sizes didn't change when working with an earlier version of this series. Only things that have changes since them is dependency calculation on the new autoconf.mk file and rebasing to top of tree.
Cheers, g.

From: Grant Likely grant.likely@secretlab.ca
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.

Unfortunately this breaks building with older (GCC-3.x) compilers.

The effect is even more nasty, as make will not stop afgter the error; if you ignore the "compilation of header file requested" message, but continues until it runs into problems later (when linking).

In message 20071121053731.19848.87826.stgit@trillian.cg.shawcable.net you wrote:
These 2 patches enable conditional compilation at the Makefile level in u-boot. Using this we can finally start getting rid of the #ifdef/#endif wrappers around every .c file.
Wolfgang, I've also pushed this to the 5xxx git tree (see below). This change is much easier to merge, but is far more risky (because it's the first one). If we're doing a short cycle just for build changes, then this is probably the best time to do it.
I've tested with MAKEALL and verified image sizes didn't change when working with an earlier version of this series. Only things that have changes since them is dependency calculation on the new autoconf.mk file and rebasing to top of tree.
Cheers, g.
The following changes since commit f92edbd8a0ef16a2b9127cbb564c09685728e4b0: Grant Likely (1): Merge branch 'origin' into kconfig-for-1.3.1
are available in the git repository at:
git://www.denx.de/git/u-boot-mpc5xxx.git master
Grant Likely (2): [BUILD] Generate include/autoconf.mk from board config files [BUILD] conditionally compile common/cmd_*.c in common/Makefile
Merged into u-boot-testing repo.
Previous state is now in mainline.
Thanks a lot.
Best regards,
Wolfgang Denk
