PCI ports differ between Marvell SoCs, but have the same compatible in FDT.
Identification is made based on parent compatible during attach.
For ArmadaXP skipping enable procedure is necessary. To achieve it
sc_skip_enable_procedure flag is used.
For Armada38x find root procedure is necessary. For other SoCs root link is
always at slot 0. sc_enable_find_root_slot flag is used to select proper
behaviour.
Marvell armv5 platforms does not support msi.

Defining INTRNG remove some necessary registers and declarations of
pic_init_secondary, pic_ipi_send, pic_ipi_read and pic_ipi_clear.
Because Marvell ArmadaXP and Armada38X always use INTRNG, include all
INTRNG code and remove code that does not use it.
Separate pic registers declarations for Armada38X are unnecessary, it
works properly with ArmadaXP config.

Device removal code does not set spa_indirect_vdevs_loaded for pools
that never experienced device removal. At least one visual consequence
of it is completely blocked speculative prefetcher. This patch sets
the variable in such situations.
This can be used to check existing images but will be used in the future to
find EFI ESP images placed in El Torito catalogs so they can be used for
hybrid boot purposes.

captured and reported the highest window advertisement with the same
SEQ/ACK. However, the window comparison uses modulo 2**16 math, rather
than directly comparing the absolute values. Because windows use
absolute values and not modulo 2**16 math (i.e. they don't wrap), we
need to compare the absolute values.

The Zynq/Zedboard GPIO driver attempts to tri-state all GPIO pins on
boot up but the order in which I reset the hardware can cause the pins
to be briefly held low before being tri-stated. This is a problem on
boards that use GPIO pins to reset devices.
In particular, the Zybo and ZC-706 boards use a GPIO pin as a USB PHY
reset. If U-boot enables the USB port before booting the kernel, the
GPIO driver attach causes a glitch on the USB PHY reset and the USB
port loses power. My fix is to have the GPIO driver leave the pins in
whatever configuration U-boot placed them.

Effectively disabling the mode changing bits in the loader. No matter which
way we go with it, it seems to be wrong- either the firmware doesn't change
the resolution and reports the resolution we requested, or the firmware
changes the resolution and doesn't report the resolution we requested. It
some cases, it does the right thing, but the bad cases outweight those.
Interested individuals can still set efi_max_resolution to 1080p or whatnot
in loader.conf(5) to restore the new behavior, but the new behavior does not
work out well for many cases.

The TCB is read using a memory window right now. A better alternate to
get self-consistent, uncached information would be to use a GET_TCB
request but waiting for a reply from hw while holding non-sleepable

As with AIM64, map the DMAP at the beginning of the fourth "quadrant" of
memory, and move the KERNBASE to the the start of KVA.
Eventually we may run the kernel out of the DMAP, but for now, continue
booting as it has been.
It should fix ck_pr_[load|store]_ptr on mips and riscv, make sure no
*fence instructions are used on i386, as older cpus don't support it, and
make sure we don't rely on gcc builtins that can lead to calls to
libatomic when linked with -O0.

The division added in r331732 meant that we wouldn't attempt a
background laundering until at least v_free_target - v_free_min clean
pages had been freed by the page daemon since the last laundering. If
the inactive queue is depleted but not completely empty (e.g., because
it contains busy pages), it can thus take a long time to meet this
threshold. Restore the pre-r331732 behaviour of using a non-zero
background laundering threshold if at least one inactive queue scan has
elapsed since the last attempt at background laundering.

The processor is "parked" in a spin-loop already and that's sufficient
for the reset. There is nothing that stop_cpus() would add here, only
extra complexity and fragility.
The original processor does not need to enable interrupts now, in fact,
it must not do that.

This commit splits all of the logodefs/graphics out into their own own files
and provides a method for these files to register their logodefs with the
drawer. Graphics are now loaded on demand if they don't exist in the current
set of logodefs.
The drawer module becomes a little easier to navigate through without all of
the graphics mixed in. It's also easy to do one-off graphics like the
9.2 Die Hard tribute by dteske@ without adding even more to our memory
requirements.
- No need for a 'goto' when our entire loop body is then wrapped in a
conditional.
- No need to leave commented out prints laying around
- If an expression is clearly going to be either nil or an expression that
isn't likely to be a boolean, we might as well use `or` to specify a
default value for the expression. e.g. `loader.getenv(...) or "no"`
The previous iteration of this assumed that {module}_load was set. In the
old world order of default loader.conf(5), this was probably a safe
assumption given that we had almost every module explicitly not-loaded in
it.
In the new world order, this is no longer the case, so one could delete a
_load line inadvertently while leaving a _name, _type, _flags, _before,
_after, or _error. This would have caused a confusing Lua error and borked
module loading.
When I implemented my EFI support I failed to check if the upstream version
of makefs in NetBSD had done the same. Override my version with theirs to
make it easier to stay in sync with them in the future.

(which sets MK_AUTO_OBJ=yes) and installkernel (which sets MK_AUTO_OBJ=no)
are run as separate steps. r329232 partially fixed this scenario by removing
MAKEOBJDIR, but it seems the AUTO_OBJ setting also needs to be on the same
