Add 'copy_staging' command to control this. For now, by default the
old mode of copying kernel to 2M phys is retained. It is going to be

On amd64, add some slop to the staging area to satisfy both requirements
of the kernel startup allocator, and to have space for minor staging data

'staging_slop' to control its size.

Compressed debug was enabled by default in commit c910570e75, but
broke the build on big-endian targets, and so was disabled in
89ed2ecb14.
Older versions of LLD fail with big-endian compressed debug sections.
This was fixed in LLD upstream (commit c6ebc651b6fa) and merged to
FreeBSD main (commit d69d07569e) by dim.
External toolchains (e.g. the llvm12 package) will not yet have the fix.
These may be used to link against base system .a archives, so compressed
debug sections would cause trouble even though the base system is fixed.
Enable compressed debug sections again, for little-endian targets only.
As discussed on freebsd-hackers[1] I expect to undo this in the future
(using compressed debug everywhere), once fixed versions of lld are
widely available.
Note that to be pedantically correct we should check both the compiler
and the linker for compressed debug support, but given the external
toolchain constraint the extra complexity does not seem worthwhile.

This has been present since the first revision of the file. The debugf
macros have always been unused so it doesn't actually do anything
useful, and besides, debugging should not be unconditionally turned on
for a production driver. Moreover, this breaks the riscv LINT kernel
build as sys/conf/NOTES includes options DEBUG, resulting in a macro
redefinition error. This does not show up in the arm64 LINT kernel build
since that has an explicit nooptions DEBUG, which is dubious and should
be revisited. Rather than copy such a hack to riscv's NOTES, fix this
specific instance of DEBUG breaking.

If we allocate a new window for a bridge rather than reusing an existing
one set up by firmware to cover all the devices then the new window only
includes the range needed for the first device to allocate the resource.
If a request comes in to adjust this resource in order to extend a
downstream window for another device then this will fail as the rman
doesn't have any space, so we must first grow the bridge's own window.
This is needed to support successfully attaching more than one PCI
device on SiFive's HiFive Unmatched, which has the following topology:
Root Port <---> Bridge <---> Bridge <-+-> Bridge <---> (Unused)
(pcib0) (pcib1) (pcib2) | (pcib3)
+-> Bridge <---> xHCI
| (pcib4)
+-> Bridge <---> M.2 E-key
| (pcib5)
+-> Bridge <---> M.2 M-key
| (pcib6)
+-> Bridge <---> x16 slot
(pcib7)
Without this, the xHCI endpoint successfully attaches but NVMe M.2 M-key
endpoint fails to attach as, when its adjacent bridge (pcib6) attempts
to allocate a window from its parent (pcib2) on the other side of the
switch, its parent attempts to grow its own window by calling
bus_adjust_resource on its own parent (pcib1) which fails to call the
root port device (pcib0) to request more memory to grow its own window.
Had the root port been directly connected to the switch without the
bridge in the middle then the existing code would have worked, but the
extra hop broke it.

The FU740 has a very similar controller and will reuse most of the
driver. This also drops the dependency on the device-tree include for
the binding indices; the header doesn't namespace its contents (and nor
does the FU740 one) so using both would require seperate translation
units which would be unnecessarily complicated just to avoid defining
local copies of the small number of constants.
Whilst here, add the missing l to gemgxlclk's name and drop the prci_
prefix from tlclk's name as we don't prefix any of the others and it's
entirely unnecessary.

If the cn_flags also indicates if the open is for Reading, Writing or Both,

This patch defines two new cn_flags bits called OPENREAD and OPENWRITE

Similar to TSO, iSCSI segmentation offload permits the upper layers to
submit a "large" virtual PDU which is split up into multiple segments
(PDUs) on the wire. Similar to how the TCP/IP headers are used as
templates for TSO, the BHS at the start of a large PDU is used as a
template to construct the specific BHS at the start of each PDU. In
particular, the DataSN is incremented for each subsequent PDU, and the
'F' flag is only set on the last PDU.
struct icl_conn has a new 'ic_hw_isomax' field which defaults to 0,
but can be set to the largest virtual PDU a backend supports. If this
value is non-zero, the iSCSI target and initiator use this size
instead of 'ic_max_send_data_segment_length' to determine the maximum
size for SCSI Data-In and SCSI Data-Out PDUs. Note that since PDUs
can be constructed from multiple buffers before being dispatched, the
target and initiator must wait for the PDU to be fully constructed
before determining the number of DataSN values were consumed (and thus
updating the per-transfer DataSN value used for the start of the next
PDU).
The target generates large PDUs for SCSI Data-In PDUs in
cfiscsi_datamove_in(). The initiator generates large PDUs for SCSI
Data-Out PDUs generated in response to an R2T.
