VME.h: VME API; BSP and bridge-chip independent VMEConfig.h: defines BSP specific constants for VME configuration vmeconfig.c configures the VME bridge using the VME.h API calls and BSP specific constants from VMEConfig.h. Independent of the bridge chip, however. vme_universe.c: implements VME.h for the vmeUniverse driver. o other universe BSP --> use its own vmeConfig.h; may reuse vmeconfig.c, vme_universe.c o other non-universe BSP --> use its own VMEConfig.h and vme_xxx.c; may reuse vmeconfig.c
