Highlights: - elfboot.c Now can load images to the ram location where linuxBIOS is running - Added the standalone directory for bootloaders built from the linuxBIOS source Other things: - Correctly maode fallback_boot.c conditional - Added entry32.lds to do the math for segment descriptor table entries - Merged ldscript.cacheram and ldscript.base - Moved assembly code to the sections .rom.text and .rom.data - Modified linuxBIOS so C code completely runs from RAM as the SiS630 case does - Updated and commented example config files for the supermicro p4dc6 - Bumped the elfboot loader version to 1.0 - Removed extra carriage returns in dump_northbridge.inc (DOS->UNIX) - General cleanups to the config of the supermicro p4dc6
