4866f95d76 Change fb_attach() and fb_detach() to take a integer unit number rather
than a dev_t.

All of the dev_t's passed were bogusly created with makedev()

bf920dafa4 Add a driver for creator upa frame buffers found in many sparc64 machines.
These are fixed resolution and operate only in pixel mode so they present
a challenge to syscons (square peg, round hole, etc, etc).  The driver
provides a video driver interface for syscons and a separate character
device for X to mmap.  Wherever possible the creator's accelarated graphics
functions are used so text mode is very fast.

Based roughly on the openbsd driver.

fe9d118aa2 o Explicitly cast the second argument to bus_space_set_region_#()
to intptr_t. This fixes a compiler warning (integer from pointer
   without cast) in scvgarndr.c when SC_PIXEL_MODE is defined.
o  Define readb() and writeb(). Both are used in scvgarndr.c when,
   guess what, SC_PIXEL_MODE is defined.

Both changes are ia64 specific.

637068b1d3 Low risk amd64 fix. Use a vm_offset_t for the virtual location of the
buffer space instead of a u_int32_t.  Otherwise the upper 32 bits of
the address space get truncated and syscons blows up.

ae3c9aff52 Unbreak alpha and ia64 builds. The previous change made the inclusion
of <machine/pc/bios.h> specific to i386 and added a conditional define
for BIOS_PADDRTOVADDR that depends on ISA_HOLE_START. The latter is
undefined on alpha and ia64. Since the former is defined the same on
both alpha and ia64, assume the ISA_HOLE_START dependent definition
is specific to amd64 and use the identity-mapping in all other cases.

This of course is getting uglier every day...

0ba311ef3a Keep syscons specific I/O functions internal/specific to syscons on
ia64 by defining them in terms of newbus. Add a static inline for
fillw(), which doesn't have anything to do with I/O.
It's still ugly, but now the ugliness can be removed from ia64
specific headers.

227f9a1c58 - Add vm_paddr_t, a physical address type. This is required for systems
where physical addresses larger than virtual addresses, such as i386s
  with PAE.
- Use this to represent physical addresses in the MI vm system and in the
  i386 pmap code.  This also changes the paddr parameter to d_mmap_t.
- Fix printf formats to handle physical addresses >4G in the i386 memory
  detection code, and due to kvtop returning vm_paddr_t instead of u_long.

Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.

b4b138c27f Including <sys/stdint.h> is (almost?) universally only to be able to use

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

07159f9c56 Cleanup of the d_mmap_t interface.
- Get rid of the useless atop() / pmap_phys_address() detour.  The
  device mmap handlers must now give back the physical address
  without atop()'ing it.
- Don't borrow the physical address of the mapping in the returned
  int.  Now we properly pass a vm_offset_t * and expect it to be
  filled by the mmap handler when the mapping was successful.  The
  mmap handler must now return 0 when successful, any other value
  is considered as an error.  Previously, returning -1 was the only
  way to fail.  This change thus accidentally fixes some devices
  which were bogusly returning errno constants which would have been
  considered as addresses by the device pager.
- Garbage collect the poorly named pmap_phys_address() now that it's
  no longer used.
- Convert all the d_mmap_t consumers to the new API.

I'm still not sure wheter we need a __FreeBSD_version bump for this,
since and we didn't guarantee API/ABI stability until 5.1-RELEASE.

f41325db5f With this commit, I hereby pronounce gensetdefs past its use-by date.
Replace the a.out emulation of 'struct linker_set' with something
a little more flexible.  <sys/linker_set.h> now provides macros for
accessing elements and completely hides the implementation.

The linker_set.h macros have been on the back burner in various
forms since 1998 and has ideas and code from Mike Smith (SET_FOREACH()),
John Polstra (ELF clue) and myself (cleaned up API and the conversion
of the rest of the kernel to use it).

The macros declare a strongly typed set.  They return elements with the
type that you declare the set with, rather than a generic void *.

For ELF, we use the magic ld symbols (__start_<setname> and
__stop_<setname>).  Thanks to Richard Henderson <rth@redhat.com> for the
trick about how to force ld to provide them for kld's.

For a.out, we use the old linker_set struct.

NOTE: the item lists are no longer null terminated.  This is why
the code impact is high in certain areas.

The runtime linker has a new method to find the linker set
boundaries depending on which backend format is in use.

linker sets are still module/kld unfriendly and should never be used
for anything that may be modular one day.

21c3015a24 * Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
  which call busspace.
* Rework pci config accesses to route through the pcib device instead of
  calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.
