Two modules with the same name cannot be loaded, so Marvell specific drivers
cannot have the same name as generic drivers.
Files with the same name, even in different folder overlaps their .o files.
Change armada38x/rtc.c to armada38x/armada38x_rtc.c fix it.
Preparation for adding this driver to GENERIC config for ARMv7
Marvell platforms.

It will be needed by hn(4) to configure its RSS key and hash
type/function in the transparent VF mode in order to match VF's
RSS settings. The description of the transparent VF mode and
the RSS hash value issue are here:
https://svnweb.freebsd.org/base?view=revision&revision=322299https://svnweb.freebsd.org/base?view=revision&revision=322485
These are generic enough to promise two independent IOCs instead
of abusing SIOCGDRVSPEC.
Setting RSS key and hash type/function is a different story,
which probably requires more discussion.
Comment about UDP_{IPV4,IPV6,IPV6_EX} were only in the patch
in the review request; these hash types are standardized now.

superblocks created in revision 322297 only works on disks
with sector sizes up to 4K. This update allows the recovery
information to be created by newfs and used by fsck on disks
with sector sizes up to 64K. Note that FFS currently limits
filesystem to be mounted from disks with up to 8K sectors.
Expanding this limitation will be the subject of another
commit.

There is no big need to burn CPU if other side may be not there yet. For
example, the PLX hardware by default enables the NTB link up on reset, not
dependig on driver to do it. In case of Intel hardware this also reduces
race between MSI-X workaround negotiation and upper layers, using the same
scratchpad registers in different time.

This creates conflicts with FreeBSD variations that may use it. The
usage of the flag M_TOOBIG is limited to iflib queue, thus using
one of M_PROTO flags is fine. There is no need to grab global flag.

In theory this allows to avoid one more expensive doorbell register read
later in some scenarios. But in practice it also significantly increases
packet rate on PLX hardware, that I can't explain yet, possibly work-

compatible string to check if the board is compatible with a given quirk.
It's possible this will be moved later, however as it's currently only used
by the MP code put it there.
So far the only instance of a quirk is when the list of CPUs may be
incorrect. This can happen on virtual machines with a hard coded
devicetree, but where the user may then set the number of CPUs as an
argument. This is the case on the ARM models so include the model specific
compat strings for these, including the spelling mistake found in some of
the OpenplatformPkg dtb files.

Record the file path for boot1.efi as the UEFI environemnt variable
FreeBSDBootVarGUID:Boot1Path. Record the device this came from as
FreeBSDBootVarGUID:Boot1Dev. While later stages of the boot may be
able to guess these values by retrieving UEFIGlobal:BootCurrent and
groveling through the correct UEFIGlobal:BootXXXX, this provides
certanty in the face of behavior from any part of the boot loader
chain that might "guess" what to do next. These env variables are
volatile and will disappear on reboot.

In the FreeBSD UEFI boot protocol, boot1.efi exits back to UEFI if it
can't boot the image for most reasons (so that further items in the
EFI boot manger list can be tried). Rename panic to efi_panic, make it
static and give it an extra status argument. Exit back to UEFI with
that status argument so the next loader can be tried.
Use malloc/free exclusively instead of mixing malloc/free and
AllocatePool/FreePool. The code is smaller.

Print the device that boot1.efi was loaded from. Print the path as

The default value for arc_no_grow_shift may not be optimal when using
several GiB ARC. Expose it via sysctl allows users to tune it easily.
Also expose arc_grow_retry via sysctl for the same reason. The default value of
60s might, in case of intensive load, be too long.

This driver supports both NTB-to-NTB and NTB-to-Root Port modes (though
the second with predictable complications on hot-plug and reboot events).
I tested it with PEX 8717 and PEX 8733 chips, but expect it should work
with many other compatible ones too. It supports up to two NT bridges
per chip, each of which can have up to 2 64-bit or 4 32-bit memory windows,
6 or 12 scratchpad registers and 16 doorbells. There are also 4 DMA engines
in those chips, but they are not yet supported.
While there, rename Intel NTB driver from generic ntb_hw(4) to more specific
ntb_hw_intel(4), so now it is on par with this new ntb_hw_plx(4) driver and
alike to Linux naming.

In particular, MIPS now has COMPAT_FREEBSD32 for n64 kernels so this
cannot be ignored for n64. On the other hand, it is unneeded for o32
MIPS kernels as the issue is only present when using 64-bit registers,
so remove the workaround from o32 kernels.
