The default KERNLOADADDR does not work on MALTA hardware. On my platform the
"First free SDRAM address" reported by YAMON is 0x800b6e61.
So use a conservative KERNLOADADDR of 0x80100000.

Merge support for very early alchemy port. I wouldn't merge this
except I don't want it to get lost when we retire projects/mips.
Should be consiered pre-alpha at this stage. Also, alchemy is now
owned by rmi, but started out life as a separate processor line, so
I'm leaving it in its own directory rather than try to shoe-horn it
into the unrelated rmi directory. Its future location is an open
question.

Define __ELF_WORD_SIZE appropriately for n64. Note for N32 I believe

device in the table based on the count rather than the maxcount.
Also the previous code didn't work properly as it would have been
necessary to reserve the entire maxcount range in order keep later
requests from filling the spare MSIs between count and maxcount,
which would be complicated to unreserve in fire_release_msi().
- For MSIs with filters rather than handlers only don't clear the
event queue interrupt via fire_intr_clear() since given that these
are executed directly would clear it while we're still processing
the event queue, which in turn would lead to lost MSIs.
- Save one level of indentation in fire_setup_intr().
- Correct a bug in fire_teardown_intr() which prevented it from
correctly restoring the MSI in the resource, causing allocation of
a resource representing an MSI to fail after the first pass when
repeatedly loading and unloading a driver module.

as this only allows us to access file systems that EFI knows about.
With a loader that can only use EFI-supported file systems, we're
forced to put /boot on the EFI system partition. This is suboptimal
in the following ways:
1. With /boot a symlink to /efi/boot, mergemaster complains about
the mismatch and there's no quick solution.
2. The EFI loader can only boot a single version of FreeBSD. There's
no way to install multiple versions of FreeBSD and select one
at the loader prompt.
3. ZFS maintains /boot/zfs/zpool.cache and with /boot a symlink we
end up with the file on a MSDOS file system. ZFS does not have
proper handling of file systems that are under Giant.
Implement a disk device based on the block I/O protocol instead and
pull in file system code from libstand. The disk devices are really
the partitions that EFI knows about.
This change is backward compatible.

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.

now type sema_t is a structure which can be put in a shared memory area,
and multiple processes can operate it concurrently.
User can either use mmap(MAP_SHARED) + sem_init(pshared=1) or use sem_open()
to initialize a shared semaphore.
Named semaphore uses file system and is located in /tmp directory, and its
file name is prefixed with 'SEMD', so now it is chroot or jail friendly.
In simplist cases, both for named and un-named semaphore, userland code
does not have to enter kernel to reduce/increase semaphore's count.
The semaphore is designed to be crash-safe, it means even if an application
is crashed in the middle of operating semaphore, the semaphore state is
still safely recovered by later use, there is no waiter counter maintained
by userland code.
The main semaphore code is in libc and libthr only has some necessary stubs,
this makes it possible that a non-threaded application can use semaphore
without linking to thread library.

The PCIR_BIOS BAR does include type bits like other BARs. Instead, it is

- Fix bus_generic_rl_(alloc|release)_resource() to not attempt to fetch a
resource list for grandchild devices, but just pass those requests up to
the parent directly. This worked by accident previously, but it is
better to not let bus drivers try to operate on devices they do not
manage.
o Optimize for memory mapped I/O by making all I/O port acceses function
calls and marking the test for the IA64_BUS_SPACE_IO tag with
__predict_false(). Implement the I/O port access functions in a new
file, called bus_machdep.c.
o Change the bus_space_handle_t for memory mapped I/O to the virtual
address rather than the physical address. This eliminates the PA->VA
translation for every I/O access. The handle for I/O port access is
still the port number.
o Move inb(), outb(), inw(), outw(), inl(), outl(), and their string
variants from cpufunc.h and define them in bus.h. On ia64 these are
not CPU functions at all. In bus.h they are merely aliases for the
new I/O port access functions defined in bus_machdep.h.
o Handle the ACPI resource bug in nexus_set_resource(). There we can
do it once so that we don't have to worry about it whenever we need
to write to an I/O port that is really a memory mapped address.
The upshot of this change is that the KBI is better defined and that I/O
port access always involves a function call, allowing us to change the
actual implementation without breaking the KBI. For memory mapped I/O the
virtual address is abstracted, so that we can change the VA->PA mapping
in the kernel without causing an KBI breakage. The exception at this time
is for bus_space_map() and bus_space_unmap().

- For SSDs use TRIM feature of DATA SET MANAGEMENT command, as defined by
ACS-2 specification working draft.
- For CompactFlash use CFA ERASE command, same as ad(4) does.
With this patch, `newfs -E /dev/ada1` was able to restore write speed of
my heavily weared OCZ Vertex SSD (firmware 1.4) up to the initial level
for the most part of it's capacity. Previous 1.3 firmware, even reportiong
TRIM capabilty bit set, was not working, reporting ABORT error for every
DSM command.
I have no idea whether it is normal, but for some reason it takes 200ms
to handle any TRIM command on this drive, that was making delete extremely
slow. But TRIM command is able to accept long list of LBAs and the length of
that list seems doesn't affect it's execution time. Implemented request
clusting algorithm allowed me to rise delete rate up to reasonable numbers,
when many parallel DELETE requests running.

the Sun Fire V215/V245 and Sun Ultra 25/45 machines. This driver also
already includes all the code to support the `Oberon' Uranus to PCIe
bridges found in the Fujitsu-Siemens based Mx000 machines but due to
lack of access to such a system for testing, probing of these bridges
is currently disabled.
Unfortunately, the event queue mechanism of these bridges for MSIs/
MSI-Xs matches our current MD and MI interrupt frameworks like square
pegs fit into round holes so for now we are generous and use one event
queue per MSI, which limits us to 35 MSIs/MSI-Xs per Host-PCIe-bridge
(we use one event queue for the PCIe error messages). This seems
tolerable as long as most devices just use one MSI/MSI-X anyway.
Adding knowledge about MSIs/MSI-Xs to the MD interrupt code should
allow us to decouple the 1:1 mapping at the cost of no longer being
able to bind MSIs/MSI-Xs to specific CPUs as we currently have no
reliable way to quiesce a device during the transition of its MSIs/
MSI-Xs to another event queue. This would still require the problem
of interrupt storms generated by devices which have no one-shot
behavior or can't/don't mask interrupts while the filter/handler is
executed (like the older PCIe NICs supported by bge(4)) to be solved
though.
