* Makefile.am, shared/flash, shared/flash/flash.c, shared/flash/flashPgm.h, shared/flash/flashPgmPvt.h, shared/flash/intelFlash.c, shared/flash/spansionFlash.c: Added flash programmer API, implementation and chip drivers for some intel + spansion flash chips (as found on mvme5500, mvme6100 and mvme3100 boards). A more appopriate place would probably be libchip but I don't know if the API is acceptable and if the implementation is generic enough (e.g., no CFI support) so I leave it here for now.
