15d107308f Add a new -B flag for use with list mode (-l) that lists details about
bridges.  Currently this includes information about what resources a
bridge decodes on the upstream side for use by downstream devices including
bus numbers, I/O port resources, and memory resources.  Windows and bus
ranges are enumerated for both PCI-PCI bridges and PCI-CardBus bridges.

To simplify the implementation, all enumeration is done by reading the
appropriate config space registers directly rather than querying the
bridge driver in the kernel via new ioctls.  This does result in a few
limitations.

First, an unimplemented window in a PCI-PCI bridge cannot be accurately
detected as accurate detection requires writing to the window base
register.  That is not safe for pciconf(8).  Instead, this assumes that
any window where both the base and limit read as all zeroes is
unimplemented.

Second, the PCI-PCI bridge driver in a tree has a few quirks for
PCI-PCI bridges that use subtractive decoding but do not indicate that
via the progif config register.  The list of quirks is duplicated in
pciconf's source.

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

The pd_name field of struct pci_conf is an array, so it can never be null.

84b755dfe5 Add support for displaying VPD for PCI devices via pciconf.
- Store the length of each read-only VPD value since not all values are
  guaranteed to be ASCII values (though most are).
- Add a new pciio ioctl to fetch VPD for a single PCI device.  The values
  are returned as a list of variable length records, one for the device
  name and each keyword.
- Add a new -V flag to pciconf's list mode which displays VPD data for
  each device.

389c8bd51e Align the PCI Express #defines with the style used for the PCI-X
#defines.  This also has the advantage that it makes the names more
compact, iand also allows us to correct the non-uniform naming of
the PCIM_LINK_* defines, making them all consistent amongst themselves.

This is a mostly mechanical rename:
  s/PCIR_EXPRESS_/PCIER_/g
  s/PCIM_EXP_/PCIEM_/g
  s/PCIM_LINK_/PCIEM_LINK_/g

When this is MFC'd, #defines will be added for the old names to assist
out-of-tree drivers.

770e4c5bc0 Only attempt to list extended capabilities for devices that have a
PCI-express capabilities.  Non-PCI-express PCI devices may simply ignore
the upper bits in a config register address effectively aliasing the
device ID register to 0x100 rather than returning 0xFFFFFFFF.  Previously
the code relied on these reads returning 0xFFFFFFFF.
