 *  Changelog:
 *   20-Oct-1996 RMK    Created
 *   31-Dec-1997 RMK    Fixed definitions to reduce warnings
 *   11-Jan-1998 RMK    Uninlined to reduce hits on cache
 *   08-Feb-1998 RMK    Added __virt_to_bus and __bus_to_virt
 *   21-Mar-1999 RMK    Renamed to memory.h
 *           RMK  Added TASK_SIZE and PAGE_OFFSET

 * Physical DRAM offset.
#define PHYS_OFFSET     UL(0x10000000)

 * These are exactly the same on the RiscPC as the
 * physical memory view.
#define __virt_to_bus(x) __virt_to_phys(x)
#define __bus_to_virt(x) __phys_to_virt(x)

 * Cache flushing area - ROM
#define FLUSH_BASE_PHYS       0x00000000
#define FLUSH_BASE            0xdf000000

 * Sparsemem support.  Each section is a maximum of 64MB.  The sections
 * are offset by 128MB and can cover 128MB, so that gives us a maximum
 * of 29 physmem bits.
#define MAX_PHYSMEM_BITS      29
#define SECTION_SIZE_BITS     26
