o Remove All Rights Reserved from my notices
o imp@FreeBSD.org everywhere
o regularize punctiation, eliminate date ranges
o Make sure that it's clear that I don't claim All Rights reserved by listing
All Rights Reserved on same line as other copyright holders (but not
me). Other such holders are also listed last where it's clear.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
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.
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).
- 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.

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.

Enable the bits in this register so low voltage 16-bit cards may work.

once there, but I removed it when I added the alignment issues.

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.
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.
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.

work with the new bridges.
# I don't plan on porting it to oldcard, but will happily commit to

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

o Protect .h against multiple includes.
o eliminate the pointers to the read/write routines. The

field.
o Print a warning if the requested map address is > 16M and

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.
