0a4dfa3cb8 Add support for the StrataFlash on 2348 boards:
o add bus shim for cfi driver
o add static mapping for CS0 (we map all 16M as the cfi driver doesn't
  support demand mapping)

Note this needs some tweaking to work for 2358 boards which is why the
CAMBRIA config is not touched.

73288922b2 Don't over-commit the DMA. Use the passed in size of the transfer
rather than a fixed 512...  This fixes the mount root problem on at91.
Prior to the SD card reorg, all data transfers were 512 bytes, so we
didn't notice.

e68dc65ae1 Store at91_master_clock in a global variable as opposed to a compile
time constant.  This allows us to potentially change it at runtime or
autodetect it early in the boot (the latter being much more likely to

43f8f3168f o The f_max is really at91_master_clock / 2, not 30MHz, so compute it as such.
o Only set 4-bit caps on those boards that have 4-bit caps (this means that
  because we don't set wire4 yet, this forces us to always use 1-bit bus).
o Don't test wire4 when setting up the bus width, since bad things will
  happen if we do.

# This likely won't fix the busted at91 sd card support, but these are
# needful changes for correctness.

9a3c731c25 Fix confusing naming of Marvell ARM CPU specific routines.
- The contents of 'feroceon_cpufuncs' dispatch table was really dedicated for the
  new Sheeva CPU (in 88F6xxx and MV-78xxx SOCs), and NOT Feroceon.

o add support for IXP435 cpu's (e.g. 64 irq's)
o add support for Cambria-specific devices: npe, led's (front panel and
  octal latch), ehci, mcu, ide cf
o redo memory mapping for xscale/ixp4xx boards: previously memory
  was assumed aliased to 0x10000000 but this appears to be true only
  for ixp425 systems and breaks operation on others; rework so memory
  is assumed to start at 0
o rework NPE configuration support to use NPE id's instead of port #'s;
  these changes also rename the associated MAC's to follow the NPE's
  they are attached to
o update npe firmware to latest rev (same license) and update default fw
  imageid's to match; in particular this adds NPE-A and crypto support
o re-style NPE fw handling code and add a console msg identifying the
  attributes of the loaded fw
o fix numerous problems with handling failures during npe setup
o fix npe rx q setup; need to spin waiting for mailbox responses during
  early boot stages as qmgr interrupts are not delivered; this fixes
  the problem where all 8 traffic classifications were not tied to the
  rx q (and eliminates the console msg "remember to fix rx q setup")
o add DELAY to npe MII wait logic for IXP435
o strip down builtin phys->virt address translation table in resource
  handling to just those resources that require it and add a console msg
  to alert people when this (kludge) table needs to be extended
o purge a bunch of dead netbsd-ism's
o cleanup avila led driver
o add Cambria support to boot2 and rework code for better multi-board support

Notes:
  1. NPE-A doesn't work and causes NPE-C to stop working; it is disabled
     in the hints
  2. USB isn't working yet; controller communicates ok but device
     discovery fails
  3. Cambria support must be configured separately from IXP425 boards;
     multi-board support is TBD

gives you the same chip support that the binary hal did but you
must also include

options AH_SUPPORT_AR5416

It is now possible to control the chip support included in a
build by specifying exactly which chips are to be supported
in the config file; consult ath_hal(4) for information.

d-cache (most ARMs) when write-allocate feature is enabled, we can have
modified but unflushed content pertaining to this physical page still in the
d-cache due to its primary (pre-existing) mapping. In such scenario that
cached content upon flush is likely to overwrite [portions of] the physical
page we want to zero here..

This is a general problem with multiple virtual mappings covering the same
physical page with write-allocate and virtual d-cache: there is inherent
potential for corruptions of this kind, which are not easily resolved; it is
best policy that such multiple mappings be not allowed.

4efdef565f Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.

This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

9b394a3293 Add locking to the various iicbus(4) bridge drivers:
- Just grab Giant in the ixp425_iic(4) driver since this driver uses
  a shared address/data register window pair to access the actual
  I2C registers.  None of the other ixp425 drivers lock access to these
  shared address/data registers yet and that would need to be done before
  this could use any meaningful locking.
- Add locking to the interrupt handler and 'iicbus_reset' methods of the
  at91_twi(4) driver.
- Add locking to the pcf(4) driver.  Other pcf(4) fixes include:
  - Don't needlessly zero the softc.
  - Use bus_foo rather than bus_space_foo and remove bus space tag and
    handle from softc.
- The lpbb(4) driver just grabs Giant for now.  This will be refined later
  when ppbus(4) is locked.
- As was done with smbus earlier, move the DRIVER_MODULE() lines to match
  the bus driver (either iicbus or iicbb) to the bridge driver into the
  bridge drivers.

ALT_BREAK_TO_DEBUGGER.  In addition to "Enter ~ ctrl-B" (to enter the
debugger), there is now "Enter ~ ctrl-P" (force panic) and
"Enter ~ ctrl-R" (request clean reboot, ala ctrl-alt-del on syscons).

We've used variations of this at work.  The force panic sequence is
best used with KDB_UNATTENDED for when you just want it to dump and
get on with it.

The reboot request is a safer way of getting into single user than
a power cycle.  eg: you've hosed the ability to log in (pam, rtld, etc).
It gives init the reboot signal, which causes an orderly reboot.

I've taken my best guess at what the !x86 and non-sio code changes
should be.

This also makes sio release its spinlock before calling KDB/DDB.

8d647da1ed Now that all platforms use genclock, shuffle things around slightly
for better structure.

Much of this is related to <sys/clock.h>, which should really have
been called <sys/calendar.h>, but unless and until we need the name,
the repocopy can wait.

In general the kernel does not know about minutes, hours, days,
timezones, daylight savings time, leap-years and such.  All that
is theoretically a matter for userland only.

Parts of kernel code does however care: badly designed filesystems
store timestamps in local time and RTC chips almost universally
track time in a YY-MM-DD HH:MM:SS format, and sometimes in local
timezone instead of UTC.  For this we have <sys/clock.h>

<sys/time.h> on the other hand, deals with time_t, timeval, timespec
and so on.  These know only seconds and fractions thereof.

Move inittodr() and resettodr() prototypes to <sys/time.h>.
Retain the names as it is one of the few surviving PDP/VAX references.

Move startrtclock() to <machine/clock.h> on relevant platforms, it
is a MD call between machdep.c/clock.c.  Remove references to it
elsewhere.

Remove a lot of unnecessary <sys/clock.h> includes.

Move the machdep.disable_rtc_set sysctl to subr_rtc.c where it belongs.

- On amd64, i386, and powerpc this is effectively a NOP.
- On arm, don't bother masking the interrupt unless the ithread is
  scheduled in the non-INTR_FILTER case to match what INTR_FILTER did.
  Also, don't bother unmasking the interrupt in the post_filter case if
  we never masked it.  The INTR_FILTER case had been doing this by having
  arm_unmask_irq for the post_filter (formerly 'eoi') hook.
- On ia64, stray interrupts are now masked for the non-INTR_FILTER case.
  They were already masked in the INTR_FILTER case.
- On sparc64, use the a NULL pre_ithread hook and use intr_enable_eoi() for
  both the 'post_filter' and 'post_ithread' hooks to match what the
  non-INTR_FILTER code did.
- On sun4v, retire the ithread wrapper hack by using an appropriate

c04bb048f6 Simplify the interrupt code a bit:
- Always include the ie_disable and ie_eoi methods in 'struct intr_event'
  and collapse down to one intr_event_create() routine.  The disable and
  eoi hooks simply aren't used currently in the !INTR_FILTER case.
- Expand 'disab' to 'disable' in a few places.
- Use function casts for arm and i386:intr_eoi_src() instead of wrapper
  routines since to trim one extra indirection.

9c113163fb Add preliminary support for binding interrupts to CPUs:
- Add a new intr_event method ie_assign_cpu() that is invoked when the MI
  code wishes to bind an interrupt source to an individual CPU.  The MD
  code may reject the binding with an error.  If an assign_cpu function
  is not provided, then the kernel assumes the platform does not support
  binding interrupts to CPUs and fails all requests to do so.
- Bind ithreads to CPUs on their next execution loop once an interrupt
  event is bound to a CPU.  Only shared ithreads are bound.  We currently
  leave private ithreads for drivers using filters + ithreads in the
  INTR_FILTER case unbound.
- A new intr_event_bind() routine is used to bind an interrupt event to
  a CPU.
- Implement binding on amd64 and i386 by way of the existing pic_assign_cpu
  PIC method.
- For x86, provide a 'intr_bind(IRQ, cpu)' wrapper routine that looks up
  an interrupt source and binds its interrupt event to the specified CPU.
  MI code can currently (ab)use this by doing:

	intr_bind(rman_get_start(irq_res), cpu);

  however, I plan to add a truly MI interface (probably a bus_bind_intr(9))
  where the implementation in the x86 nexus(4) driver would end up calling
  intr_bind() internally.

De-hardcode usage of ARM_TP_ADDRESS and RAS local storage, and move this
special purpose page to a more convenient place i.e. after the vectors high
page, more towards the end of address space. Previous location (0xe000_0000)
caused grief if KVA was to go beyond the default limit.

Note that ARM world rebuilding is required after this change since the
location of ARM_TP_ADDRESS is shared between kernel and userland.

4c1734c71d Bring in the nice work from Mark Tinguely on arm pmap.
The only downside is that it renames pmap_vac_me_harder() to pmap_fix_cache().
From Mark's email on -arm :
pmap_get_vac_flags(), pmap_vac_me_harder(), pmap_vac_me_kpmap(), and
pmap_vac_me_user() has been rewritten as pmap_fix_cache() to be more
efficient in the kernel map case. I also removed the reference to
the md.kro_mappings, md.krw_mappings, md.uro_mappings, and md.urw_mappings
counts.

In pmap_clearbit(), we can also skip over tests and writeback/invalidations
in the PVF_MOD and PVF_REF cases if those bits are not set in the pv_flag.
PVF_WRITE will turn caching back on and remove the PV_MOD bit.

In pmap_nuke_pv(), the vm_page_flag_clear(pg, PG_WRITEABLE) has been moved
to the pmap_fix_cache().

We can be more agressive in attempting to turn caching back on by calling
pmap_fix_cache() at times that may be appropriate to turn cache on
(a kernel mapping has been removed, a write has been removed or a read
has been removed and we know the mapping does not have multiple write
mappings to a page).

In pmap_remove_pages() the cpu_idcache_wbinv_all() is moved to happen
before the page tables are NULLed because the caches are virtually
indexed and virtually tagged.

In pmap_remove_all(), the pmap_remove_write(m) is added before the
page tables are NULLed because the caches are virtually indexed and
virtually tagged. This also removes the need for the caches fixing routine
(whichever is being used pmap_vac_me_harder() or pmap_fix_cache()) to be
called on any of these mappings.

In pmap_remove(), I simplified the cache cleaning process and removed
extra TLB removals. Basically if more than PMAP_REMOVE_CLEAN_LIST_SIZE
are removed, then just flush the entire cache.
