Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.

No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Fix the build.

Replace several bus_alloc_resource() calls using default arguments with bus_alloc_resource_any()

Since these calls only use default arguments, bus_alloc_resource_any() is the
right call.

Differential Revision: https://reviews.freebsd.org/D5306

o break newbus api: add a new argument of type driver_filter_t to
bus_setup_intr()

o add an int return code to all fast handlers

o retire INTR_FAST/IH_FAST

Use BUS_PROBE_DEFAULT for pci probe return value

Start each of the license/copyright comments with /*-, minor shuffle of lines

Add missing <sys/module.h> includes

Reduce differences with cy_isa.c: fixed an unsorted include.

Remove unused includes.

Adjust pathnames for the move from i386/isa to dev/cy.

Adjust staticness and a variable name for the split of cy.c into cy.c and
cy_isa.c. Use the new header required for the split to avoid repeating
declarations in cy_pci.c.

Converted the isa probe and attach to new-bus so that this driver works
without the (defunct) isa compatibility shims. The new-bus-specific
parts are very similar to the ones for the pci probe and attach.

This was held up too long waiting for a repo copy to src/sys/dev/cy,
so I decided to fix the files in their old place. This gives easier
to read and merge diffs anyway.

The "count" line in src/sys/conf/files won't be changed until after
the repo copy, so old kernel configs that specify a count need not be
(and must not be) changed until then. The count is just ignored in
the driver. One unfinished detail is dynamic allocation of arrays
with <count> and (<count> * 32) entries, and iteration over the arrays.
This is now kludged with a fixed count of 10 (up to 10 cards with up
to 32 ports each).

Fixed some minor indentation bugs.

Fixed breakage of the pci case of the cy driver by the new interrupt
code. Both the driver and the new code were wrong. Driver interrupt
handlers are supposed to take "void *vsc" arg, but some including all
COMPAT_ISA drivers and the pci part of the cy driver want an "int unit"
arg. They got this using bogus casts of function pointers which should
have kept working despite their bogusness. However, the new interrupt
code doesn't honor requests to pass an arg of ((void *)0), so things
are very broken if the arg is actually a representation of unit 0.

The fix is to use a normal "void *vsc" arg for the pci case and a
wrapper for the COMPAT_ISA case (of the cy driver). This cleans up
new-busification of the pci case but takes the COMPAT_ISA case a little
further from new-bus. The corresponding bug for the COMPAT_ISA case
has already been fixed similarly using a wrapper in compat_isa.c and
we need another wrapper just to undo that.

Fixed some directly related style bugs (mainly by removing compatibility
cruft).

cy.c:
Fixed an indirectly related old bug in cyattach_common(). A wrong status
was returned in the unlikely event that malloc() failed.

Use __FBSDID().

- Express hard dependencies on bus (pci, isa, pccard) and
network layer (ether).
- Don't abuse module names to facilitate ifconfig module loading;
such abuse isn't really needed. (And if we do need type information
associated with a module then we should make it explicit and not
use hacks.)

Remove __P.

Work around a PLX9050 bug that causes system lockup in certain systems,
depending on the MMIO addresses allocated to the board.

Merged cy_pcireg.h into the one file that uses it (cy_pci.c).

Fixed breakage of interrupt setup in previous commit. It used an
uninitialized variable in the !CY_PCI_FASTINTR case (*blush*).

Converted to new-bus.

Disable cy - it is now completely broken and needs non-trivial work.

Special case for compiling LINT - just give a warning and continue on.
At least we have a chance at getting test compile coverage for the rest
of the kernel now.

Make LINT compile again.

Ahhrggg. Put the test for the compat shims AFTER the file that includes
them.

Pointed out by: bde

Per conversations in -current, add #error to these drivers when you don't
have the right compatibility shims enabled. ISA drivers to follow later.

$Id$ -> $FreeBSD$

Eliminate a bunch of #include "pci.h" and #if NPCI > 0 around entire
files. config will leave the whole file out if configured to do so.

Detect PCI device IDs for latest boards. Simplified the ID comparisons.

Submitted by: Ivan Passos <ivan@cyclades.com> (rewritten by me)

Simplify the COMPAT_PCI_DRIVER/DATA_SET hack. We can add:
#define COMPAT_PCI_DRIVER(name,data) DATA_SET(pcidevice_set,data)
.. to 2.2.x and 3.x if people think it's worth it. Driver writers can do
this if it's not defined. (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)

Make this compile with CY_PCI_FASTINTR again.

Use COMPAT_PCI_DRIVER() for registration if it exists. This shouldn't
hurt the driver portability to 3.x too much for where drivers are shared.

Added missing newline to "no ports found!" message.

Use a fast interrupt handler for the PCI version of the cy driver
if option CY_PCI_FASTINTR is configured and mapping the irq to a
fastintr is possible. Unfortunately, this has to be optional because
pci_map_int_right() doesn't handle the INTR_EXCL flag right --
INTR_EXCL is honoured even if the interrupt needs to be non-exclusive
for other devices to work.

Fixed minor style bugs in previous commit.

Updated for not-so-new version of Cyclom-Y PCI boards (with a custom
register for the PLX id). Merge the vendor's modification of the 2.2.*
release version into -current for reference. Will be cleaned up in next
commit.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been

serial adapter, and support for multiple Cyclom controllers.
