39e3e683e5 Move device 'cs' into i386/pc98 specific NOTES. It is broken on ppc
because it uses i386 specific calls.  Maybe it could be added to
amd64, but I'm not so sure it would work there so I've not added it
there.

6f55457493 - Use PCIR_BAR() macro for the BAR for the aperture.
- Axe macros used for walking PCI capabilities list.  We now ask the PCI
  bus to find caps for us rather than doing it in the drm and agp drivers.

1bbc1eaa87 - Bump FreeBSD version for the hostb(4) and vgapci(4) drivers as well as
the addition of pci_find_extcap().
- Change the drm drivers to attach to vgapci.  This is #ifdef'd so the
  code can be shared across branches.
- Use pci_find_extcap() to look for AGP and PCIE capabilities in drm.
- GC all the drmsub stuff for i810/i830/i915.  The agp and drm devices are
  now both children of vgapci.

bf7979fcfe Add a vgapci(4) stub device driver for VGA PCI devices. This device serves
as a bus so that other drivers such as drm(4), acpi_video(4), and agp(4)
can attach to it thus allowing multiple drivers for the same device.  It
also removes the need for the drmsub hack for the i8[13]0/i915 drm and agp
drivers.

062cc3da2d Change the various AGP drivers that attach to the Host-PCI bridge device to
attach to the hostb driver instead.  This means that agp can now be loaded
at runtime (in theory at least).  Also, the drivers no longer have to
explicity call device_verbose() to cancel out any earlier calls to
device_quiet() by the hostb(4) driver (this shows a limitation in new-bus,
drivers really shouldn't be doing device_quiet() until they know they are
going to drive that device, i.e. in attach).

fde66b5a2e Move the hostb driver out of the i386 and amd64 PCI code (where it was
duplicated anyways) and into a single MI driver.  Extend the driver a bit
to implement the bus and PCI kobj interfaces such that other drivers can
attach to it and transparently act as if their parent device is the PCI
bus (for the most part).

9f22e2f35e Don't map the AGP aperture into contiguous KVA. The various graphics
drivers already map sections into KVA as needed anyway.  Note that this

54f0fa09ad Add a new method PCI_FIND_EXTCAP() to the pci bus interface that is used
to search for a specific extended capability.  If the specified capability
is found for the given device, then the function returns success and
optionally returns the offset of that capability.  If the capability is
not found, the function returns an error.

b98bf8f1d5 Reduce Giant scope a bit, as fdrop() is believed to be MPSAFE.
The purpose of this change is consistency (not performance improvement:)),
as it was hard to tell if fdrop() is MPSAFE or not when I saw it sometimes
under the Giant and sometimes without it.

239343cecc If LOADER_BZIP2_SUPPORT is defined allocate heap in the 1MB-4MB range to
provide enough room for decompression (up to 2.5MB is necessary). This
should be safe to do since we load i386 kernels after 8MB mark now, so
that 16MB is the minimum amount of RAM necessary to even boot FreeBSD.

This makes bzip2-support  practically useable.

85788ffcca Long-long time ago, when the trees were large and memory expensive amount of
memory directly available to loader(8) and friends was limited to 640K on i386.
Those times have passed long time ago and now loader(8) can directly access
up to 4GB of RAM at least theoretically. At the same time, there are several
places where it's assumed that malloc() will only allocate memory within
first megabyte.

Remove that assumption by allocating appropriate bounce buffers for BIOS
calls on stack where necessary.

This allows using memory above first megabyte for heap if necessary.

cb3a140c1c Bump __FreeBSD_version to 700009 because:
1. The ELF-64 typedefs are now standardized, so that the libelf port
   (devel/libelf) does not need to compensate for not having the
   Elf64_Xword and Elf64_Sxword types.
2. ELF Symbol versioning support has been added. This also affects
   the libelf port (though configure should detect this correctly).
