Summary:
The AmigaOne platform, encompassing the X5000 and A1222 at this time, is
based on the mpc85xx platform, but includes some things not listed in
the device tree. Some custom devices, like CPLD, could be added to the
device tree with an overlay, or other means. However, some cannot
easily be done, such as the power button interrupt.
The directory will also become a location to add AmigaOne platform drivers,
such as the aforementioned CPLD, and its children.

support Energy Efficient Ethernet. Prior to this patch, X552 devices
(device ID 0x15AB) will crash the system when transitioning EEE state

Linkage is controlled by two make knobs:
WANT_COMPAT - Prefer to link against the compat ABI.
NEED_COMPAT - Link against the compat ABI or fail to build.
Supported values are "32", "soft", and "any". The latter meaning pick
the first[0] supported compat ABI.
This can be used to provide test binaries for compat ABIs or to link
ABI-specific programs.
[0] We currently support only one compat ABI at a time, but this may
change in the future and some code in this commit is structured to ease
that change.

Rescan a PCI bus when the ACPI_NOTIFY_BUS_CHECK event is posted to a

Install ACPI notify handlers on PCI devices with an _EJ0 method. This
handler is invoked when devices are added or removed.
- When an ACPI_NOTIFY_DEVICE_CHECK event posts, rescan the parent bus
device. Note that strictly speaking we only need to rescan the
specified device, but BUS_RESCAN is what is available, so we rescan
the entire bus.
- When an ACPI_NOTIFY_EJECT_REQUEST event posts, detach the device
associated with the ACPI handle, invoke the _EJ0 method, and then
delete the device.
Eventually this might be changed to vector notify events to devd in
userspace where devctl can be used instead to permit more complex
actions such as graceful unmounting of filesystems.

GCC compilers set __FreeBSD__ statically to a build-time determined
targeted version (which in ports always matches the build host's
version). This means that when building any version (12 or 13, etc.)
of riscv or some other architecture via GCC on a 12.x host,
__FreeBSD__ will always be set to 12. As a result, __FreeBSD__ cannot
be used to reliably detect the target FreeBSD version being built.
Instead, __FreeBSD_version from either <sys/param.h> (in the kernel)
or <osreldate.h> (in userland) should be used.
This changes the gets() test in libc++ to use __FreeBSD_version from
<osreldate.h>.

- Set the endianness (via MIPS_ENDIAN) and ABI (via MIPS_ABI) in
CFLAGS from MACHINE_ARCH. ARCH_FLAGS now only sets a different
-march value if needed.
- TRAMP_ARCH_FLAGS inherits MIPS_ENDIAN from MACHINE_ARCH but does
not set the ABI since XLPN32 needs an N64 ABI for the trampoline
loader. When TRAMP_ARCH_FLAGS is used it must set both -march

10572 Fix race in dnode_check_slots_free()
https://www.illumos.org/issues/10572
The Fix from ZoL:
Currently, dnode_check_slots_free() works by checking dn->dn_type
in the dnode to determine if the dnode is reclaimable. However,
there is a small window of time between dnode_free_sync() in the
first call to dsl_dataset_sync() and when the useraccounting code
is run when the type is set DMU_OT_NONE, but the dnode is not yet
evictable, leading to crashes. This patch adds the ability for
dnodes to track which txg they were last dirtied in and adds a
check for this before performing the reclaim.
This patch also corrects several instances when dn_dirty_link was
treated as a list_node_t when it is technically a multilist_node_t.

By default next_cmd() initializes only first u32 of opcode. O_ICMP6TYPE
opcode has array of bit masks to store corresponding ICMPv6 types.
An opcode that precedes O_ICMP6TYPE, e.g. O_IP6_DST, can have variable
length and during opcode filling it can modify memory that will be used
by O_ICMP6TYPE opcode. Without explicit initialization this leads to
creation of wrong opcode.
