new-bus: Remove the 'rid' and 'type' arguments from BUS_RELEASE_RESOURCE

The public bus_release_resource() API still accepts both forms, but
the internal kobj method no longer passes the arguments.
Implementations which need the rid or type now use rman_get_rid() or
rman_get_type() to fetch the value from the allocated resource.

newbus: Move from bus_child_{pnpinfo,location}_src to bus_child_{pnpinfo,location} with sbuf

Now that the upper layers all go through a layer to tie into these
information functions that translates an sbuf into char * and len. The
current interface suffers issues of what to do in cases of truncation,
etc. Instead, migrate all these functions to using struct sbuf and these
issues go away. The caller is also in charge of any memory allocation
and/or expansion that's needed during this process.

Create a bus_generic_child_{pnpinfo,location} and make it default. It
just returns success. This is for those busses that have no information
for these items. Migrate the now-empty routines to using this as
appropriate.

Document these new interfaces with man pages, and oversight from before.

sys/dev: further adoption of SPDX licensing ID tags.

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.

Fix device delete child function.

When detaching device trees parent devices must be detached prior to
detaching its children. This is because parent devices can have
pointers to the child devices in their softcs which are not
invalidated by device_delete_child(). This can cause use after free
issues and panic().

Device drivers implementing trees, must ensure its detach function
detaches or deletes all its children before returning.

While at it remove now redundant device_detach() calls before
device_delete_child() and device_delete_children(), mostly in
the USB controller drivers.

Replace some more default range checks with RMAN_IS_DEFAULT_RANGE().

This is a follow-on to r295832.

Convert rman to use rman_res_t instead of u_long

Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources. For
now, this is still compatible with u_long.

This is step one in migrating rman to use uintmax_t for resources instead of
u_long.

Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.

This change has been broken out to facilitate MFC'ing drivers back to 10 without

Fix interrupt handling.

PR: kern/140947

Fix interrupt handling. It started off broken and grew worse over time.
The rewrite of the interrupt handler includes:
o loop until all pending interrupts are handled. This closes a
race condition.
o count the number of interrupt sources we handled so that we can
properly return FILTER_HANDLED or FILTER_STRAY when we break out
of the loop.
o When matching the interrupt source to the devices that have that
source pending, check only from the set of devices we found to
have a pending interrupt.

Fix building with GCC 4.2: ensure types are defined before refering to them.

Rewrite of puc(4). Significant changes are:
o Properly use rman(9) to manage resources. This eliminates the
need to puc-specific hacks to rman. It also allows devinfo(8)
to be used to find out the specific assignment of resources to
serial/parallel ports.
o Compress the PCI device "database" by optimizing for the common
case and to use a procedural interface to handle the exceptions.
The procedural interface also generalizes the need to setup the
hardware (program chipsets, program clock frequencies).
o Eliminate the need for PUC_FASTINTR. Serdev devices are fast by
default and non-serdev devices are handled by the bus.
o Use the serdev I/F to collect interrupt status and to handle
interrupts across ports in priority order.
o Sync the PCI device configuration to include devices found in
NetBSD and not yet merged to FreeBSD.
o Add support for Quatech 2, 4 and 8 port UARTs.
o Add support for a couple dozen Timedia serial cards as found
in Linux.

Use bus_setup_intr() rather than invoking BUS_SETUP_INTR() directly so that
puc still prints out [FAST] on Peter's box.

Don't enable PUC_FASTINTR by default in the source. Instead, enable it
via the DEFAULTS kernel configs. This allows folks to turn it that option
off in the kernel configs if desired without having to hack the source.
This is especially useful since PUC_FASTINTR hangs the kernel boot on my
ultra60 which has two uart(4) devices hung off of a puc(4) device.

I did not enable PUC_FASTINTR by default on powerpc since powerpc does not
currently allow sharing of INTR_FAST with non-INTR_FAST like the other
archs.

Eliminate tinderbox errors.

Avoid trouble with PUC_FASTINTR if it is already defined.

Now that fast interrupts can be shared we can use them in puc.

puc(4) does strange things to resources in order to fool the
subdrivers to hook up.

It should probably be rewritten to implement a simple bus to which
the sub drivers attach using some kind of hint.

Until then, provide a couple of crutch functions with big warning
signs so it can survive the recent changes to struct resource.

__RMAN_RESOURCE_VISIBLE not needed.

- sparc64/fhc/fhc.c:
Change fhc(4) to use IRQ numbers instead of RIDs for allocating the
IRQs of children. This works similar to e.g. sbus(4), i.e. add the
IRQ resources as fully specified to the resource lists of the children,
allocate them like normal. When establishing the interrupt search the
interrupt maps of the children for a matching INO to determine which
map we need to write the fully specified interrupt number to and to
enable the mapping (before the RID was used to indicate which interrupt
map to use).

- dev/puc/puc.c:
Revert rev. 1.38, with the above change fhc(4) no longer needs special
treatment for allocating IRQs.

Thanks to: joerg for providing access to an E3500

o Introduce port sub-types (eg PUC_PORT_UART_NS8250, PUC_PORT_UART_Z8530)
to handle different hardware and determine resource sizes.
o Introduce two new IVARs: PUC_IVAR_SUBTYPE and PUC_IVAR_REGSHFT. Both
are used by uart(4) to get sufficient information to talk to the HW.
o Introduce PUC_FLAGS_ALTRES to tell puc(4) to try memory mapped I/O

o Have ports of type PUC_PORT_TYPE_COM attach to uart(1) if attaching
to sio(4) fails (due to not having the sio driver).
o Put struct puc_device_description in struct puc_softc instead of
having a pointer to a device description in the softc. This allows
us to create device descriptions on the fly without having to use
malloc() or otherwise have them staticly defined.
o Move puc_find_description() from puc.c to puc_pci.c as it's specific

o Add EBUS and SBUS frontends for use on sparc64. Note that the P in
puc stands for PCI, so we kinda mess things up here. It's too soon
to worry about it though. We'll know what to do about it in time.
