 1.30  20-Feb-2024  andvar Fix format specifier for physmem from %d to 0x%"PRIxPSIZE" in multiple places.

Should fix VERBOSE_INIT_ARM for various evbarm kernel configs.
Also add 0x prefix in few previously fixed places to improve readability.
 1.29  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.28  24-Apr-2021  thorpej branches: 1.28.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

 1.25  16-Jul-2019  skrll branches: 1.25.8;
Consistently use vaddr_t as initarm and friends return type.

Makes no difference to binaries except for aarch64 where it's required
 1.24  16-Jul-2019  skrll KNF
 1.23  28-Oct-2018  skrll Fix a commit
 1.22  21-Sep-2018  skrll Centralise defparam CONSADDR, CONSPEED, CONMODE and CONADDR into

 1.19  22-Dec-2016  cherry branches: 1.19.14; 1.19.16;
switch all ports to use uvm_init.c:uvm_md_init()

uvm_setpagesize() is now subsumed within this funciton.
 1.18  13-Sep-2014  matt branches: 1.18.2; 1.18.4;
Replace more vm_offset_t, vm_size_t with vaddr_t, vsize_t
Use paddr_t for msgbufphys
 1.17  18-Aug-2013  matt <arm/locore.h> fallout (fixes some include ordering errors)
 1.16  12-Nov-2012  skrll branches: 1.16.2;
C99 types
 1.15  29-Oct-2012  chs add missing arg to cpu_setttb().
 1.14  01-Sep-2012  matt branches: 1.14.2;
Move things around for <arm/arm32/machdep.h>
 1.13  30-Jul-2012  matt More -fno-common fixes
 1.12  04-Nov-2011  aymeric add preliminary support for AT91SAM9260
 1.11  01-Jul-2011  dyoung branches: 1.11.2;
#include <sys/bus.h> instead of <machine/bus.h>.
 1.10  26-Dec-2009  uebayasi Use cpu_* prefix to call cpu_* functions (setttb() -> cpu_setttb()); no
functional changes.
 1.9  27-Nov-2009  rmind - Use uvm_lwp_setuarea() instead of directly setting address to lwp_t::l_addr.
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places. Reduce sys/user.h inclusions.
 1.8  26-Nov-2009  matt Kill proc0paddr. Use lwp0.l_addr instead.
 1.7  23-Oct-2009  snj Drop 3rd and 4th clauses. Approved by all copyright holders:
joff and Embedtronics Oy's owners (Jukka Marin and Sami Kantoluoto).
 1.6  11-Aug-2009  matt Remove all declarations of physmem from sys/arch. Add an include of
<sys/systm.h> to the one file that did not already contain it.
This now means that physmem can be changed by updating systm.h and uvm_page.c
(excluding fixing printfs)
 1.5  14-Mar-2009  dsl Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
 1.4  30-Nov-2008  martin branches: 1.4.4;
As discussed on tech-kern: mutex_init is too heavyweight for early bootstrap
phases, so move the initialization of the ksyms mutex back into main via
a function called ksyms_init. Rename the existing (but quite different)
ksyms_init* variations into ksyms_addsyms_elf() and ksyms_addsyms_explicit()
and adapt machdep code accordingly.
 1.3  12-Nov-2008  ad Remove LKMs and switch to the module framework, pass 1.

Proposed on tech-kern@.
 1.2  03-Jul-2008  matt branches: 1.2.2; 1.2.4; 1.2.6;
Add AT91 support. (XXX need to finish timecounter support).

 1.27.4.8  05-Apr-2021  thorpej Treat config_probe() as if it were a boolean function; don't compare
return value > 0... except for the odd balls, which are now really easy
to spot.
 1.27.4.7  05-Apr-2021  thorpej config_match() -> config_probe() for the straight-forward indirect config
cases. There are still a few odd balls using config_match() which should
be sorted out later.
 1.27.4.6  04-Apr-2021  thorpej CFARG_SUBMATCH -> CFARG_SEARCH for the indirect configuration uses.
 1.27.4.5  03-Apr-2021  thorpej Give config_attach() the tagged variadic argument treatment and
mechanically convert all call sites.
 1.27.4.4  22-Mar-2021  thorpej Audit CFARG_IATTR in config_found() calls, and remove it in situations
where the interface attribute is not ambiguous.
 1.27.4.3  22-Mar-2021  thorpej Mechanical conversion of config_found_sm_loc() -> config_found().
CFARG_IATTR usage needs to be audited.
 1.27.4.2  21-Mar-2021  thorpej CFARG_IATTR usage audit:

If a device carries only one interface attribute, there is no need
to specify it when calling config_search(); that specification is
meant only to disambiguate which interface attribute (which is a
proxy for "what kind of attach args are being used") is having
children attached. cfparent_match() will take care of ensuring that
any potential children can attach to one of the parent's iterface
attributes, and if the parent only carries one, no disambiguation is
necessary.
 1.27.4.1  20-Mar-2021  thorpej The proliferation if config_search_*() and config_found_*() combinations
is a little absurd, so begin to tidy this up:

- Introduce a new cfarg_t enumerated type, that defines the types of
tag-value variadic arguments that can be passed to the various
config_*() functions (CFARG_SUBMATCH, CFARG_IATTR, and CFARG_LOCATORS,
for now, plus a CFARG_EOL sentinel).
- Collapse config_search_*() into config_search() that takes these
variadic arguments.
- Convert all call sites of config_search_*() to the new signature.
Noticed several incorrect usages along the way, which will be
audited in a future commit.
 1.28.8.1  04-Aug-2021  thorpej Adapt to CFARGS().
