85cd924c0e Remove unused file. Pointed out by Pavel Cahyna. 
Probably unused since kernel config files were moved to i386/conf.

ad560fa074 Give Xen its own linker script, which does not set the physical load address 
specially. In Xen, the system is already in virtual mode when the kernel is
started, so the old behavior of setting physical address to virtual address
was actually correct, and the previous change made NetBSD/Xen kernels
unbootable.

Pointed out, explained and tested by <bouyer>.

b48d779334 Revert previous. HYPERVISOR_set_timer_op() works fine for domU, and using 
HYPERVISOR_yield() cause a domain to busy-wait for some work to do (so
using HYPERVISOR_yield doen't fix the problem for dom0, and makes things much
worse for domU).

2dba0c5647 Initialize the GT64x11 PCI timeout and retry register with a value taken 
from Linux/MIPS, which improves viaide xfer performance significantly.

5ff62d8d84 On my system the CPU frequency reported at boot is off by about 10% (maybe 
because of the jitter caused by the serial console), which is not only
cosmetic but is bad for clock accuracy. Introducing a 1s delay before reading
Xen's idea of the CPU frequency fixes this.

2a649c320b HYPERVISOR_set_timer_op() doesn't seem to work right on a NetBSD Xen3 dom0, 
the dom0 is getting a continous stream of clock interrupts. As we want an
interrupt every hz anyway, just use HYPERVISOR_yield() instead.

498d4ec7e6 The receive buffer, once mapped back in the domU, is read/write and not 
shared so there;s no problems marking the mbuf M_EXT_RW.

de9d456540 A lot of work is needed in the tcp stack to handle read-only ext storage 
so always copy packets from the domU to a fresh mbuf for now.

3b5ae171d2 New linker scripts for the i386 kernel. The main improvement is setting the 
physical load address correctly. (Before, it was set to the same very high
value as the virtual address.)

Provided by Jason Thorpe in
http://mail-index.netbsd.org/port-i386/2006/02/10/0008.html
with some modifications by me, mainly to make the output more similar to
the current one, and to not hardwire the physical and virtual addresses.

Now an unpatched grub can load a NetBSD Multiboot kernel.

5eda3c3cab Use xen_shm_* to map the packet sent to us by the domU, and attach it 
as external storage to the mbuf.

provide backend services to other domains.

c9e13db63a Implement partial support for the RS6K PCI Bridge found on 7025-F40 
models.  This code was made possible by assistance from Cory Bajus.

Add code that asks the PCI bridge what it's config base address is, and
use that when wiring up an indirect bridge type.
Move prep's user segment register to 10, because the 7025's PCI config
address is at 11, where the user segment used to be.
Add a battable entry for 0xbf800000 for machines with RS6K bridges.

There is still probably work left to be done before a 7025-F40 is fully
supported.

237137c875 Add needed framework for backend drivers. 
As we want some control on the name the backend driver will have we
can't use autoconf(9) here. Instead backend drivers registers to
xenbus, which will call a create callback when a new device is there.
Backend devices won't have a "struct device" in xenbus, use a void pointer
instead.

9458b164a6 New stdarg.h and varargs.h based on arm and i386 versions. 
Use __builtin_va_* instead of hand written code in va-sh.h that uses
LHS casts.  Slightly worse code is generated by gcc 3.3.3, but LHS
casts are outlawed in gcc 3.3.6 and gcc 4.

Build-tested on hpcsh (le) and mmeye (be), run-tested on hpcsh.
