Some MIPS board have ability to add alternate window if flash bigger than 4M, for BCM5354 chip it is 0x1c000000, when flash 8M size. Then lower 4M accessible via 0x1fc00000 and via 0x1c000000, bigger 4M only via 0x1c000000, because 0x1fc00000 segment end on 0x20000000 boundary. >> >> Warner >> _______________________________________________ >> freebsd-mips@freebsd.org mailing list >> http://lists.freebsd.org/mailman/listinfo/freebsd-mips >> To unsubscribe, send any mail to >> "freebsd-mips-unsubscribe@freebsd.org" -- Alexandr Rybalko <ray@dlink.ua>
