This patch disables outer cache sync in PL310 driver
by adding "arm,io-coherent" property. In addition to
the previous patches it was the last bit needed
for enabling proper operation of Armada 38x SoCs

Implement simple chain loader in loader; this update does add chain command,
taking device or file as argument to load and start new boot loader.
In case of BIOS, the chain will read the boot block to address 0000:7c00 and
jumps on it. In case of UEFI, the chain command is to be used with efi
application, typically stored in EFI System Partition.
The update also does add simple menu entry, if the variable chain_disk is set.
The value of the variable chain_disk is used as argument for chain loading.

This commit enables usage of HWPMC interrupts for the
Marvell SoCs, which use MPIC (Armada38x and ArmadaXP).
Those interrupts require extra unmasking, comparing to
others. Also, in order to process counters per-CPU,
they are masked/unmasked using separate registers' sets
for each core.

While it sounds like a good idea to extract the RFC1048 data from PXE, in the
end it is not and it is causing lots of issues. Our pxeloader might need
options which are incompatible with other pxe servers (for example iPXE, but
not only).
Our pxe loaders are also now settings their own user class, so it is useful to
issue our own pxe request at startup

The current read from network is working from up to down - we have some
protocol needing the data from the network, so we build the buffer space
for that protocol, add the extra space for headers and pass this buffer
down to be filled by nif get call in hope, we have guessed the incoming
packet size right. Amazingly enough this approach mostly does work, but
not always...
So, this update does work from down to up - we allocate buffer (based
on MTU or frame size info), fill it up, and pass on for upper layers.
The obvious problem is that when we should free the buffer - if at all.
In the current implementation the upper layer will free the packet on error
or when the packet is no longer needed.
While working on the issue, the additional issue did pop up - the bios
implementation does not have generic get/put interface but is using pxe
udpsend/udpreceive instead. So the udp calls are gone and undi interface
is implemented instead. Which in turn means slight other changes as we
do not need to have duplicated pxe implementation and can just use dev_net.
To align packet content, the actual read from nic is using shifted buffer by
ETHER_ALIGN (2).

gptzfsboot: error 1 lba 4294967288
gptzfsboot: error 1 lba 1
gptzfsboot: no ZFS pools located, can't boot
The first two errors above are from issuing INT13 EAX=0x4800, meaning we
need to check if EDD is available and use EAX=0x800 if not.
For an workaround I'm using the similar idea as in biosdisk.c - first probe
ah=8h, then check if we have EDD.
Note we would like to see the correct disk size info, but we *may*
get away with anything >64MB, so we could at least test 2 zfs pool labels
on whole disk setup and not to freak out the INT13 interface.
If we get away with initial disk probing, then we have partition sizes from
the partition table and we should be able to complete the disk probing.
Note: this update does not provide full fix to all errors, but we get
the drvsize() errors removed.

The current reboot command in efi/loader/main.c is passing extra data with
ResetSystem, however, UEFI spec 2.6, page 265 does state:
"ResetData is only valid if ResetStatus is something other than EFI_SUCCESS
unless the ResetType is EfiResetPlatformSpecific where a minimum amount of
ResetData is always required."
Therefore we should use DataSize 0 and ResetData NULL - those are two last

Maintaining an address family and framework has real costs when we make
infrastructure improvements. In the case of NATM we support no devices
manufactured in the last 20 years and some will not even work in modern
motherboards (some newer devices that patm(4) could be updated to
support apparently exist, but we do not currently have support).
With this change, support remains for some netgraph modules that don't
require NATM support code. It is unclear if all these should remain,
though ng_atmllc certainly stands alone.
Note well: FreeBSD 11 supports NATM and will continue to do so until at
least September 30, 2021. Improvements to the code in FreeBSD 11 are
certainly welcome.

instead of reading the pool GUID for the actual boot device (partition),

The work to implement zfs reader to inspect all pool label copies did

Since userboot is already using common/disk.c API (disk_open() etc),
the fix is quite simple - we only need to make sure the userdisk_iocl()
will call disk_ioctl(). In addition, the diskioctl callback does return
int, not pointer.

The current zfs reader is only checking first label from each device, however,
we do have 4 labels on device and we should check all 4 to be protected
against disk failures and incomplete label updates.
The difficulty is about the fact that 2 label copies are in front of the
pool data, and 2 are at the end, which means, we have to know the size of
the pool data area.
Since we have now the mechanism from common/disk.c to use the partition
information, it does help us in this task; however, there are still some
corner cases.
Namely, if the pool is created without partition, directly on the disk,
and firmware will give us the wrong size for the disk, we only can check
the first two label copies.
