is running the VSA in the geode lx northbridge. It builds but is not tested. lar.h: make LAR functions SHARED lar.c: make process_file non-static (i.e. global) vsmsetup.c: modify to use LAR functions. stage1.c: new function, init_archive, which is SHARED and will set up the initial archive struct. Note that some work remains. The use of unsigned longs and unsigned shorts should be changed to u32/u16 as Carl-Daniel has pointed out, Because this change requires changes elsewhere I am not including them in this patch.
