The semantics of  * these parameters are: * *  ROM_START      is the 32-bit target address of the start of the ROM *                 words containing dualport memory.  This is *not* *                 the address of dualport memory itself, but is the base *                 address of the rom word containing pod 0. *  *  ROMWORDWIDTH   is the number of bytes making up a 'word'.  The *                 value describes the memory sybsystem of the target, *                 not the word size of the CPU.  For example, *                 if ROM memory is organized as an array of 16 bit *                 words, this number is two.  If the processor has a *                 32-bit architecture, but only one 8-bit ROM is *                 used to provide ROM memory, this value is 1. * *  POD_0_INDEX    is the index within a rom word of pod 0.  This number *                 reflects the ROM byte emulated by pod 0.  The following *                 table shows what value to use for common word sizes *                 and podorder environment variable: *                       * *                          Word size      podorder        POD_0_INDEX *                          --------       --------        ----------- *                           8-bits     (any podorder)         0 *                          16-bits     podorder == 0:1        0 *                                      podorder == 1:0        1 *                          32-bits     podorder == 0:1:2:3    0 *                                      podorder == 3:2:1:0    3 * *  NUMACCESSES    is the number of accesses the target processor makes *                 to pod 0 in the course of reading a single 8-bit *                 value from the pod. * *  ROMSIZE        is the number of bytes in an individual ROM.  This *                 number should agree with NetROM's romtype environment *                 variable. * *  DP_BASE        is the 32-bit target address of the first byte of dualport *                 memory.  Dualport memory is always in pod 0.  The default *                 location is 2K from the end of pod 0.  The formula below *                 is correct for this default location.  If you have moved *                 dualport RAM, you must adjust the formula to give the *                 correct address.  This define should be the first argument *                 in your call to config_dpram(). * * Consult the NetROM user's manual for more information on the readaddress * protocol and on the parameters to config_dpram(). * *//*		***	PORT THIS SECTION	*** */#if 0#define	ROM_START	 0x00000000L #define	ROMWORDWIDTH     2#define	POD_0_INDEX	 0#define	NUMACCESSES	 1#define	ROMSIZE		 RS_27C020/* The following formula is correct ONLY if dualport is at the default    location, at the top of pod 0 */#define DP_BASE (ROM_START + ((ROMSIZE - DUALPORT_SIZE) * ROMWORDWIDTH))#endif#define	HASCACHE	 False #define READONLY_TARGET /* #define READWRITE_TARGET */#define VETHER#define USE_MSGS#endif	/* _dpconfig_h */
