This series extracts the u-boot configuration from the config header files and makes it usable by the build system. The obvious application for this is to allow conditional compiliation of files without wrapping every file with a large #if defined() block (which results in shorter build times).
This is another step towards using a kconfig style build system. This step just enables make and gcc to have the same configuration data. Next step I think is to allow boards to supply a Kconfig style config file instead of a header file (and in this case, do the opposite of this patch; generate the header file based on the .config file). Until all boards are ported over, both methods can be supported based on what kind of config file (either .h or .config) is present.
Word of warning: I've most certainly broken stuff in this version. If there is suppport for this direction, then I'll make sure I get it sorted out for real.
