 1.43  13-May-2024  msaitoh s/slighly/slightly/ in comment.
 1.42  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.
 1.41  12-Oct-2023  skrll Fix non-DIAGNOSTIC builds
 1.40  20-Apr-2023  skrll Provide a shared pmap_devmap implementation and convert all pmap_devmap
arrays to use DEVMAP_ENTRY{,_END}
 1.39  03-Jul-2022  andvar branches: 1.39.4;
s/bounaries/boundaries/ in comments.
 1.38  17-Aug-2021  andvar fix multiplei repetitive typos in comments, messages and documentation. mainly because copy paste code big amount of files are affected.
 1.37  18-Apr-2020  skrll PMAP_DEBUG has been deleted on arm
 1.36  18-Apr-2020  skrll Trailing whitespace
 1.35  16-Jul-2019  skrll branches: 1.35.8;
Consistently use vaddr_t as initarm and friends return type.

Makes no difference to binaries except for aarch64 where it's required
 1.34  16-Jul-2019  skrll KNF
 1.33  28-Oct-2018  skrll Fix a commit
 1.32  21-Sep-2018  skrll Centralise defparam CONSADDR, CONSPEED, CONMODE and CONADDR into
opt_console.h and adjust.
 1.31  31-Jul-2018  skrll Sprinkle #include "opt_arm_debug.h" where VERBOSE_INIT_ARM is used
 1.30  22-Dec-2016  cherry branches: 1.30.14; 1.30.16;
switch all ports to use uvm_init.c:uvm_md_init()

uvm_setpagesize() is now subsumed within this funciton.
 1.29  13-Sep-2014  matt branches: 1.29.2; 1.29.4;
Replace more vm_offset_t, vm_size_t with vaddr_t, vsize_t
Use paddr_t for msgbufphys
 1.28  18-Aug-2013  matt <arm/locore.h> fallout (fixes some include ordering errors)
 1.27  22-Sep-2012  matt branches: 1.27.2;
Don't use an asm in pmap_activate to update the TTBR, use cpu_setttb instead
but add a second argument to it to indicate whether the TLB/caches need to be
flushed. Default cortex to pmap_needs_fixup = 1. But check the MMFR3 field
to see if the fixed can be skipped.
Use a cf_flag bit 0 to indicate whether the A9 L2 cache should disable (bit 0 = 1)
or enabeld (bit = 0).

With these changes, the A9 MMU can use traverse caches to do MMU tablewalks
Also, make sure all memory has the shareable bit for the A9.
 1.26  16-Aug-2012  matt branches: 1.26.2;
Move the standard definitions of the {UND,IRQ,FIQ,ABT}_STACK_SIZE to
<arm32/machdep.h>
Move the extern for cpu_reset_address to the same file.
Add cpu_reset_address_paddr.
Kill cpu_reset_v4_MMU_disable.
if cpu_reset_address is NULL, then the MMU will be disabled.
 1.25  29-Jul-2012  matt Fix more -fno-common fallout.
Move more variables to common locations.
 1.24  01-Jul-2011  dyoung branches: 1.24.2;
#include <sys/bus.h> instead of <machine/bus.h>.
 1.23  30-Jun-2011  wiz dependant -> dependent
 1.22  28-Nov-2010  hannken As md(4) no longer has "needs-count" there is no "md.h" anymore.
Remove the inclusion of this file.

Acorn32 now always builds load_memory_disc_from_floppy(). This should
not be a problem as all configs have md(4).

Observed by: Masao Uebayashi <uebayasi@netbsd.org>
 1.21  28-Dec-2009  uebayasi branches: 1.21.4;
More setttb() -> cpu_setttb() for readability & consistency. Missing instances
pointed out by tsutsui@ & nonaka@, thanks.
 1.20  26-Dec-2009  uebayasi Use cpu_* prefix to call cpu_* functions (setttb() -> cpu_setttb()); no
functional changes.
 1.19  26-Dec-2009  uebayasi Garbage collect an unused global, vm_offset_t pagetables_start.
 1.18  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.
 1.17  26-Nov-2009  matt Kill proc0paddr. Use lwp0.l_addr instead.
 1.16  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)
 1.15  11-Nov-2008  dyoung It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.
 1.14  27-Apr-2008  matt branches: 1.14.6; 1.14.8;
Merge kernel changes in matt-armv6 to HEAD.
 1.13  19-Jan-2008  chris branches: 1.13.6; 1.13.8; 1.13.10;
Remove arm support for IPKDB.

It hasn't worked since arm was broken out from arm32 in Jan 2001, and
no-one has noticed or cared to fix it.
 1.12  17-Oct-2007  garbled branches: 1.12.2; 1.12.8;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.
 1.11  21-Aug-2007  kiyohara branches: 1.11.2;
The initarm() should initialize GPIO. We must not initialize GPIO in
foo_attach() of the each drivers. And, it is necessary to confirm whether
to be initialized in foo_match(). To avoid a dangerous configuring on the
evaluation boards.
 1.10  24-Nov-2006  wiz branches: 1.10.8; 1.10.16; 1.10.22; 1.10.24; 1.10.26;
s/independant/independent/, from Zafer.
 1.9  24-Oct-2006  bjh21 parse_mi_bootargs() is declared in <arm/arm32/machdep.h>, so there's no need
to declare it here too.
 1.8  17-May-2006  mrg branches: 1.8.8; 1.8.10;
in initarm(), initialise kernel_l1pt.pv_va as well as kernel_l1pt.pv_pa.
 1.7  08-Mar-2006  lukem branches: 1.7.2;
Use the SI capitalization for "Hz", "kHz", and "MHz" in comments and strings.
Add a space between numbers and Hz unit.
 1.6  24-Dec-2005  perry branches: 1.6.4; 1.6.6; 1.6.8; 1.6.10;
Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.
 1.5  11-Dec-2005  christos merge ktrace-lwp.
 1.4  04-Jul-2005  bsh branches: 1.4.2;
adapt to changes for PXA270 support.
 1.3  18-Mar-2005  bsh branches: 1.3.2; 1.3.4;
modify comments for clarity.

Original comments made several people misunderstand that the comment
says kernel's pagetable is at 0xa0004000. What the comment says is
about RedBoot's pagetable.
 1.2  17-Mar-2005  bsh Switch kernels for Lubbock and TwinTail to use pmap_devmap to map
I/O registers that are used in early start-up stage. Also stop using
special bootstrap-time-only bus_space_map function in {lubbock,g42xxeb}_machdep.c.

This makes initarm() for them a bit simpler, and gives us smaller diffs
to other evbarm platforms.
 1.1  26-Feb-2005  bsh branches: 1.1.2;
TWINTAIL (official product name is G4255EB) is an evaluation board
with Intel PXA255 processor from Genetec corp. You can get some
information on the board from http://ad.genetec.co.jp/ but only in Japanese.
