d9c9c81c08 sys: use our roundup2/rounddown2() macros when param.h is available.
rounddown2 tends to produce longer lines than the original code
and when the code has a high indentation level it was not really
advantageous to do the replacement.

This tries to strike a balance between readability using the macros
and flexibility of having the expressions, so not everything is
converted.

d3ec8e547e __LP64__ is what's defined, not _LP64_, according to the manual (and
also experience).

1f97c78986 First cut at fixing memory mapping botch. Nobody must use the ray(4)
driver since it couldn't have worked with NEWCARD w/o these fixes.
This should allow selecting 16-bit memory width as well (which was
what was broken).

00362cddbe - Fix exca_(io|mem)_map() to return proper errno values.
- Change exca_activate_resource() to call BUS_ACTIVATE_RESOURCE() before
  calling exca_(io|mem)_map() since the latter use rman_get_bus(tag|handle)
  and the recent changes to nexus(4) mean that you need to activate a
  resource before reading the bus tag and handle.  This was true before,
  but now the nexus(4) drivers on x86 and ia64 are more forceful about it.

e2ae5821fe exca->pccarddev should always be non-null now. Only call it when the
device is actually attached.

21de43a1ec It turns out that it is easier to not NULL out pccard and cardbus
device pointers.  They don't change as the children device drivers
come and go.  Rather, check to see if the device is attached where we
would have checked ! NULL.  This solves many asymmetries in the code
that likely could lead to crashes when loading/unloading cbb without
one or more of the expected children's driver not present.

3c48d33eec The TOPIC97 and TOPIC100 seem to have a special register in the exca
space that enables low voltage operation (and maybe other stuff).
Enable the bits in this register so low voltage 16-bit cards may work.

Existance noticed in NetBSD driver.

703ef1e74c Properly calculate the offset in mapping the memory of pccards. This
allows my 3com cards to work again.  It appears that this code was
once there, but I removed it when I added the alignment issues.

26824d8c47 CARDMEM is the offset of the address ON THE CARD (eg which page).
Instead, use EXCA_MEMREG_WIN_SHIFT which is the amount we shift the
bus address by to write into upper memory (eg above 24MB).  Use the
latter in this case.

d029ead3cb When we went to the set_flags interface for the memory resource, we
switched from PCCARD_MEM_FOO to PCCARD_A_MEM_FOO, yet we didn't change
exca in all the right places.  Do so now.  Also use PCCARD_WIDTH_AUTO
rather than the magic cookie 0.

39c50d587a A number of minor fixes to the mapping of memory. This should help
reading the CIS on some cards.  However, not all just yet.  This makes
at least some of the xircom cards that weren't working to work.  It
doesn't make my home and away card work, however.

o Don't get the card offset wrong.  This is the biggest hassle for
  reading the CIS.  The old code was just so wrong I can't believe that
  it worked at all.
o Don't set the bit that allows/forces 16-bit memory access to the
  memory.  It is hard coded with 0x80.
o Don't need to slow down memory access with wait-states.  OLDCARD didn't
  need them and it doesn't hurt anything.
o remove bogus grousying in comment.

e4e7b5bc54 Add two of three workarounds for interrupt storms for o2micro parts as
obtained from o2micro.  These should only be needed for 'older'
o2micro bridges (anything before the 7xxx series of bridges), but will
work with the new bridges.

# oldcard if someone else needs them.

o chip_name arrays ifdef'd out.
o use the OLDCARD-like get/put functions so we can support differnt types

o Write the beggings of is this a valid exca device and introduce more
  chipset support.

c3ee5891b9 First draft of common code between pccbb and pcic drivers for talking
to ExCA register sets.  These registers exist in both ISA and PCI
devices in a couple different ways, and this will provide a common
base for future building.  This code is a rehash of the pccbb 16-bit
code, which was a rehash of the pcic code, which was a rehash of the
netbsd i82365 code.  More hashing to come.
