de1c392c86 On an AS 600 5/266 (and possibly others), accessing the configuration
space of PCI devices that don't exist cause PCI master & target aborts
rather than returning ~0 or giving a machine check.  Bring in some code
from NetBSD to handle this properly.

37dec27558 Add support for SYS_RES_DENSE and SYS_RES_BWX resource types. These are
equivalent to SYS_RES_MEMORY for x86 but for alpha, the rman_get_virtual()
address of the resource is initialised to point into either dense-mapped
or bwx-mapped space respectively, allowing direct memory pointers to be
used to device memory.

8d262eb793 Add support for the DEC_ST6600 family of alphas. This includes the
Compaq XP1000, AlphaServer DS20, AlphaServer DS10, and DP264

This has been tested *only* on XP1000's.  I'll be interested to hear from
owners of other types of DEC_ST6600 alphas.

I'd like to thank Don Rice of Compaq for providing the documentation required
to support this platform on FreeBSD.  I'd also like to thank Doug Rabson for newbus,
and for helping me get a multiple hoses working with newbus.

f8d64a0d5d Add support for multiple PCI "hoses" used on various alpha platforms.
The specific intent of this commit is to pave the way for importing
Compaq XP1000 support.  These changes should not affect the i386 port.

fa628c268c Stage 1 of a cleanup of the i386 interrupt registration mechanism.
Interrupts under the new scheme are managed by the i386 nexus with the
awareness of the resource manager.  There is further room for optimizing
the interfaces still.  All the users of register_intr()/intr_create()
should be gone, with the exception of pcic and i386/isa/clock.c.

087d4857e5 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

954236024b Added support for the DEC EB64PLUS systype. (part I)
The new file pci_eb64plus_intr.s deals with the interrupt hardware
on the EB64PLUS and was obtained from NetBSD with the NetBSD
copyright intact

The apecs chipset support code was altered to allow routing interrupts
through pci if we're not running on an avanti.  Avanti's route all
interrupts through isa.

9238b8271d Fix some 64bit truncation problems which crept into SYSCTL_LONG() with the
last cleanup.  Since the oid_arg2 field of struct sysctl_oid is not wide
enough to hold a long, the SYSCTL_LONG() macro has been modified to only
support exporting long variables by pointer instead of by value.

982e80577d Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

3331f029dc * Add hooks to allow the X server to access I/O ports and memory.
* Update drivers to the latest version of the bus interface.

The ISA drivers' use of the new resource api is minimal.  Garrett has
some much cleaner drivers which should be more easily shared between
i386 and alpha.  This has only been tested on cia based machines.  It
should work on lca and apecs but I might have broken something.

6140797f7f Fix type 0 configuration accesses, and use a virtual rather than physical
address for the LCA PCI configuration register address.

FreeBSD/Alpha now boots on the NoName (aka AXPpci 33, Alpha PC), and probably
also on the Multia (mine hasn't arrived yet, so I can't tell for sure).
