d05becf2b6 Use -Wl,-N instead of the undocumented -N option for GCC.
GCC forwards the -N flag directly to ld. This flag is not documented and
not supported by (for example) Clang. Just use -Wl,-N.

5a8336816e Add support for SPARC64 V (and where it already makes sense for other
HAL/Fujitsu) CPUs. For the most part this consists of fleshing out the
MMU and cache handling, it doesn't add pmap optimizations possible with
these CPU, yet, though.
With these changes FreeBSD runs stable on Fujitsu Siemens PRIMEPOWER 250
and likely also other models based on SPARC64 V like 450, 650 and 850.
Thanks go to Michael Moll for providing access to a PRIMEPOWER 250.

9b824f84d5 Some machines can not only consist of CPUs running at different speeds
but also of different types, f.e. Sun Fire V890 can be equipped with a
mix of UltraSPARC IV and IV+ CPUs, requiring different MMU initialization
and different workarounds for model specific errata. Therefore move the
CPU implementation number from a global variable to the per-CPU data.
Functions which are called before the latter is available are passed the
implementation number as a parameter now.

606e071c41 Use the SUNW,{d,i}tlb-load methods for entering locked TLB entries like
OpenBSD and OpenSolaris do instead of fiddling with the MMUs ourselves.
Unlike direct access the firmware methods don't automatically use the
next free (?) TLB slot, instead the slot to be used has to be specified.
We allocate the TLB slots for the kernel top-down as OpenSolaris suggests
that the firmware will always allocate the ones for its own use bottom-up.
Besides being simpler, according to OpenBSD using the firmware methods is
required to allow booting on Sun Fire E10K with multi-systemboard domains.

4f607e8ef2 - Assert that HEAPSZ is a multiple of PAGE_SIZE as at least the firmware
of Sun Fire V1280 doesn't round up the size itself but instead lets
  claiming of non page-sized amounts of memory fail.
- Change parameters and variables related to the TLB slots to unsigned
  which is more appropriate.
- Search the whole OFW device tree instead of only the children of the
  root nexus device for the BSP as starting with UltraSPARC IV the 'cpu'
  nodes hang off of from 'cmp' (chip multi-threading processor) or 'core'
  or combinations thereof. Also in large UltraSPARC III based machines
  the 'cpu' nodes hang off of 'ssm' (scalable shared memory) nodes which
  group snooping-coherency domains together instead of directly from the
  nexus.
- Add support for UltraSPARC IV and IV+ BSPs. Due to the fact that these
  are multi-core each CPU has two Fireplane config registers and thus the
  module/target ID has to be determined differently so the one specific
  to a certain core is used. Similarly, starting with UltraSPARC IV the
  individual cores use a different property in the OFW device tree to
  indicate the CPU/core ID as it no longer is in coincidence with the
  shared slot/socket ID.
  While at it additionally distinguish between CPUs with Fireplane and
  JBus interconnects as these also use slightly different sizes for the
  JBus/agent/module/target IDs.
- Check the return value of init_heap(). This requires moving it after
  cons_probe() so we can panic when appropriate. This should be fine as
  the PowerPC OFW loader uses that order for quite some time now.

ccb1921ee0 - Add code allowing a network device to only be open and closed once
by keeping it opened after the first open and closing it via the
  cleanup handler when NETIF_OPEN_CLOSE_ONCE is defined in order to
  avoid the open-close-dance on every file access which with firmware
  that for example performs an auto-negotiation on every open causes
  netbooting to take horribly long. Basically the behavior with this
  knob enabled resembles the one employed between r60506 and r177108
  (and for sparc64 also again since r182919) with the addition that
  the network device now is closed eventually before entering the
  kernel and before rebooting. Actually I think this should be the
  desired MI behavior, however the U-Boot loader actually requires
  net_close() to be called after every transaction in order for some
  local shutdown operations to be performed (and which I think thus
  will break on concurrent opens, i.e. when netdev_opens is > 1, like
  the loader does at least for disks when LOADER_GZIP_SUPPORT is
  enabled).
- Use NETIF_OPEN_CLOSE_ONCE to replace the hack, which artificially
  increased netdev_opens for sparc64 in order to keep the network
  device opened forever, as at least some firmware versions require
  the network device to be closed eventually before entering the
  kernel or otherwise will DMA received packets to stale memory.
  The powerpc OFW loader probably wants NETIF_OPEN_CLOSE_ONCE to be
  set as well for the same reasons.

2611aba180 USIII and beyond CPUs have stricter requirements when it comes
to synchronization needed after stores to internal ASIs in order
to make side-effects visible. This mainly requires the MEMBAR #Sync
after such stores to be replaced with a FLUSH. We use KERNBASE as
the address to FLUSH as it is guaranteed to not trap. Actually,
the USII synchronization rules also already require a FLUSH in
pretty much all of the cases changed.
We're also hitting an additional USIII synchronization rule which
requires stores to AA_IMMU_SFSR to be immediately followed by a DONE,
FLUSH or RETRY. Doing so triggers a RED state exception though so
leave the MEMBAR #Sync. Linux apparently also has gotten away with
doing the same for quite some time now, apart from the fact that
it's not clear to me why we need to clear the valid bit from the
SFSR in the first place.

20e6aaf533 - Read ASI_{D,I}TLB_DATA_ACCESS_REG twice in order to work around
errata of USIII and beyond (USIII erratum #19, USIII+ erratum #1,
  USIIIi erratum #1).
- Use the cheetah PA mask in {d,i}tlb_va_to_pa_sun4u() for USIII
  and beyond. This is done so that these functions will still mask
  the debug bits of spitfire-class CPUs once we increase TD_PA_BITS
  to match the number of bits used for the PA by cheetah-class CPUs.
- Change {d,i}tlb_enter_sun4u() to also set TLB_CTX_KERNEL as the
  context of the mappings entered. This is more or less cosmetic as
  TLB_CTX_KERNEL is 0.
- Now that we have to distinguish between different sun4u CPUs in
  the loader anyway, no longer do trial and error when reading the

042df2e2da Enable GCC stack protection (aka Propolice) for userland:
- It is opt-out for now so as to give it maximum testing, but it may be
  turned opt-in for stable branches depending on the consensus.  You
  can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
  It is harmless to steal the knob as SSP symbols have been provided
  by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
  (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
  libc will be automatically downgraded to -fstack-protector because it
  breaks rtld otherwise.
- This option is unavailable on ia64.

Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

aa785996fd - Make better use of the global chosen, memory and mmu handles instead
of obtaining them over and over again and pretending we could do
  anything useful without them (for chosen this includes adding a
  declaration and initializing it in OF_init()).
- In OF_init() if obtaining the memory or mmu handle fails just call
  OF_exit() instead of panic() as the loader hasn't initialized the
  console at these early stages yet and trying to print out something
  causes a hang. With OF_exit() one at least has a change to get back
  to the OFW boot monitor and debug the problem.
- Fix OF_call_method() on 64-bit machines (this is a merge of
  sys/dev/ofw/openfirm.c rev 1.6).
- Replace OF_alloc_phys(), OF_claim_virt(), OF_map_phys() and
  OF_release_phys() in the MI part of the loader with wrappers around
  OF_call_method() in the sparc64. Beside the fact that they duplicate
  OF_call_method() the formers should never have been in the MI part
  of the loader as contrary to the OFW spec they use two-cell physical
  addresses.
- Remove unused functions which are also MD dupes of OF_call_method().
- In sys/boot/sparc64/loader/main.c add __func__ to panic strings as
  different functions use otherwise identical panic strings and make
  some of the panic strings a tad more user-friendly instead of just
  mentioning the name of the function that returned an unexpected
  result.

1b279bfb52 - Change the code that determines whether to use a serial console and
which serial device to use in that case respectively to not rely on
  the OFW names of the input/output and stdin/stdout devices. Instead
  check whether input and output refers to the same device and is of
  type serial (uart(4) was already doing this) and for the fallback
  to a serial console in case a keyboard is the selected input device
  but unplugged do the same for stdin and stdout in case the input
  device is nonexistent (PS/2 and USB keyboards) or has a 'keyboard'
  property (RS232 keyboards). Additionally also check whether the OFW
  did a fallback to a serial console in the same way in case the
  output device is nonexistent. While at it save on some variables
  and for sys/boot/sparc64/loader/metadata.c move the code in question
  to a new function md_bootserial() so it can be kept in sync with
  uart_cpu_getdev_console() more easily.
  This fixes selecting a serial console and the appropriate device
  when using a device path for the 'input-device' and 'output-device'
  OFW environment variables instead of an alias for the serial device
  to use or when using a screen alias that additionally denotes a
  video mode (like e.g. 'screen:r1024x768x60') but no keyboard is
  plugged in (amongst others). It also makes the code select a serial
  console in case the OFW did the same due to a misconfiguration like
  both 'input-device' and 'output-device' set to 'keyboard' or to a
  nonexisting device (whether the OFW does a fallback to a serial
  console in case of a misconfiguration or one ends up with just no
  console at all highly depends on the OBP version however).
- Reduce the size of buffers that only ever need to hold the string
  'serial' accordingly. Double the size of buffers that may need to
  hold a device path as e.g. '/pci@8,700000/ebus@5/serial@1,400000:a'
  exceeds 32 chars.
- Remove the package handle of the '/options' node from the argument
  list of uart_cpu_getdev_dbgport() as it's unused there and future
  use is also unlikely.

fa662cc9b2 To quote the submitter:
"...If "keyboard" is the selected input-device and "screen" the
output-device (both via /options) but the keyboard is unplugged,
OF automatically switches to ttya for the console, it even prints
a line telling so on "screen". Solaris respects this behaviour and
uses ttya as the console in this case and people probably expect
FreeBSD to do the same (it's also very handy to temporarily switch
consoles)..."
"...I changed the comparison of the console device with "ttya" ||
"ttyb" to "tty" because on AXe boards all 4 onboard UARTs end in
SUB-D connectors (ttya and ttyb being 16550 and ttyc and ttyd a
SAB82532) and there's no Sun keyboard connector (but PS/2). If one
plugs a serial card in a box there also can be more than just ttya
and ttyb available for a console..."
