* supervisor mode so the VBR may be changed. It places the address of the
* function that makes a 167Bug .RETURN syscall in the trap 13 entry in the
* exception vector, and then issues a trap 13 call. It is also possible that
* the code was copied from some other OS that does run tasks in user mode.
* In any case, it appears to be a bit of paranoia, and could lead to
* problems if 167Bug is invoked before we get to switch the VBR back to
* 167Bug because trap 13 is documented as being reserved for the internal
* use of the debugger.

/* page_table.c
*
* The code submitted by Eric Vaitl <vaitl@viasat.com> for the MVME162 appears
* to be for a uniprocessor implementation. The function that sets up the
* page tables, page_table_init(), is not data driven. For all processors, it
* sets up page tables to map virtual addresses from 0x20000 to 0x3FFFFF to
* physical addresses 0x20000 to 0x3FFFFF. This presumably maps a subset of
* a local 4 MB space, which is probably the amount of RAM on Eric Vailt's
* MVME162.
*
* It is possible to set up the various bus bridges in the MVME167s to create
* a flat physical address space across multiple boards, i.e., it is possible
* for each MVME167 in a multiprocessor system to access a given memory
* location using the same physical address, whether that location is in local
* or VME space. Addres translation can be set up so that each virtual address
* maps to its corresponding physical address, e.g. virtual address 0x12345678
* is mapped to physical address 0x12345678. With this mapping, the MMU is
* only used to control the caching modes for the various regions of memory.
* Mapping the virtual addresses to their corresponding physical address makes
* it unnecessary to map addresses under software control during the
* initialization of RTEMS, before address translation is turned on.
*
* With the above approach, address translation may be set up either with the
* transparent address translation registers, or with page tables. If page
* tables are used, a more efficient use of page table space can be achieved
* by sharing the page tables between processors. The entire page table tree
* can be shared, or each processor can hold a private copy of the top nodes
* which point to leaf nodes stored on individual processors.
*
* In this port, only the transparent address translation registers are used.
* We map the entire virtual range from 0x0 to 0x7FFFFFFF to the identical
* physical range 0x0 to 0x7FFFFFFF. We rely on the hardware to signal bus
* errors if we address non-existent memory within this range. Our two
* MVME167s are configured to exist at physical addresses 0x00800000 to
* 0x00BFFFFF and 0x00C00000 to 0x00FFFFFF respectively. We map the space
* from 0x0 to 0x7FFFFFFF as copyback, unless jumper J1-5 is removed, in
* which case we map as writethrough. If jumper J1-7 is removed, the data
* cache is NOT enabled. If jumper J1-6 is removed, the instruction cache
* is not enabled.

* These functions are prototyped in rtems/c/src/lib/include/timerdrv.h and
