Machine privilege level was specially designed to use in vendor's

mode in FreeBSD as part of understanding RISC-V ISA, but it is time
to remove it.
We now use BBL (Berkeley Boot Loader) -- standard RISC-V firmware,
which provides operation in machine mode for us.
We now use standard SBI calls to machine mode, instead of handmade
'syscalls'.
o Remove HTIF bus.
HTIF bus is now legacy and no longer exists in RISC-V specification.
HTIF code still exists in Spike simulator, but BBL do not provide
raw interface to it.

OpenZFS uses feature flags instead of a zpool version number to track
features since the split from Oracle. In addition to avoiding confusion
on ZFS vs OpenZFS version numbers, this also allows features to be added
to different operating systems that use OpenZFS in different order.
The previous zfs boot code (gptzfsboot) and loader (zfsloader) blindly
tries to read the pool, and if failed provided only a vague error message.
With this change, both the boot code and loader check the MOS features
list in the ZFS label and compare it against the list of features that
the loader supports. If any unsupported feature is active, the pool is
not considered as a candidate for booting, and a helpful diagnostic
message is printed to the screen. Features that are merely enabled via
zpool upgrade, but not in use, do not block booting from the pool.

parse() is the boot loader's interp_parse.c is too naive about quotes
both single and double quotes were allowed to be mixed, and single
quotes did not follow the usual semantics (re variable expansion).
The old code did not check for terminating quotes
This update implements:
* distinguishing single and double quote
* variable expansion will not be done inside single quote protected area
* will preserve inner quote for values like "value 'some list'"
* ending quote check.
this diff does not implement ending quote order check, it shouldn't
be too hard, needs some improvements on parser state machine.

Summary:
This driver supports the following methods to trigger gathering random bits from the hardware:
1. interrupt when the FIFO is full (default) fed into the harvest queue
2. callout (when BCM2835_RNG_USE_CALLOUT is defined) every second if hz is less than 100, otherwise hz / 100, feeding the random bits into the harvest queue
If the kernel is booted with verbose enabled, the contents of the registers will be dumped after the RBG is started during the attach routine.
Author: hackagadget_gmail.com (Stephen J. Kiernan)
Test Plan: Built RPI2 kernel and booted on board. Tested the different methods to feed the harvest queue (callout, interrupt) and the interrupt driven approach seems best. However, keeping the other method for people to be able to experiment with.

There is no reason to return non-zero value from zfs_probe_partition()
as that causes following partitions to not be probed for ZFS vdevs.
A particular scenario that I encountered is a GPT partitioned disk
where several partitions have freebsd-zfs type. A partition with a lower
index is used as a cache (l2arc) vdev and in that case case zfs_probe()
returned a non-zero status. That status was returned to ptable_iterate()
and caused it to abort the iteration. Because of that the subsequent
partitions were not probed and a root pool was not discovered resulting
in a boot failure.
While there fix the style for nearby return statements.

memory resource in DTS to reflect that. This change is needed to support

In consequence, CESA_WRITE and CESA_READ macros have been split depending
on which range of registers is accessed. Offsets for CESA registers have

In r277943, the efinet_match() routine was changed to use an off by one
when matching network interfaces. The effect was that using "net1"
actually used the device attached to "net0".
Digging into the hardware that needed this workaround more, I found that
UEFI was creating two simple network protocol devices for each physical
NIC. The first device was a "raw" Ethernet device and the second device
was a "IP" device that used the IP protocol on top of the underlying
"raw" device. The PXE code in the firmware used the "IP" device to pull
across the loader.efi, so currdev was set to "net1" when booting from the
physical interface "net0". (The loaded image's device handle referenced
the "IP" device that "net1" claimed.)
However, the IP device isn't suitable for doing raw packet I/O (and the
current code to open devices exclusively actually turns the "IP" devices
off on these systems).
To fix, change the efinet driver to only attach to "raw" devices. This
is determined by fetching the DEVICE_PATH for each handle which supports
the simple network protocol and examining the last node in the path. If
the last node in the path is a MAC address, the device is assumed to be
a "raw" device and is added as a 'netX' device. If the last node is not
a MAC address, the device is ignored.
However, this causes a new problem as the device handle associated with
the loaded image no longer matches any of the handles enumerated by
efinet for systems that load the image via the "IP" device. To handle
this case, expand the logic that resolves currdev from the loaded image
in main(). First, the existing logic of looking for a handle that
matches the loaded image's handle is tried. If that fails, the device
path of the handle that loaded the loaded image is fetched via
efi_lookup_image_devpath(). This device path is then walked from the
end up to the beginning using efi_handle_lookup() to fetch the handle
associated with a path. If the handle is found and is a known handle,
then that is used as currdev. The effect for machines that load the
image via the "IP" device is that the first lookup fails (the handle
for the "IP" device isn't claimed by efinet), but walking up the
image's device path finds the handle of the raw MAC device which is used
as currdev.
With these fixes in place, the hack to subtract 1 from the unit can now
be removed, so that setting currdev to 'net0' actually uses 'net0'.

- efi_lookup_devpath() uses the DEVICE_PATH_PROTOCOL to obtain the
DEVICE_PATH for a given EFI handle.
- efi_lookup_image_devpath() uses the LOADED_IMAGE_DEVICE_PATH_PROTOCOL
to lookup the device path of the device used to load a loaded image.
- efi_devpath_name() uses the DEVICE_PATH_TO_TEXT_PROTOCOL to generate
a string description of a device path. The returned string is a CHAR16
string that can be printed via the recently added '%S' format in
libstand's printf(). Note that the returned string is returned in
allocated storage that should be freed by calling
efi_free_devpath_name().
- efi_devpath_last_node() walks a DEVICE_PATH returning a pointer to the
final node in the path (not counting the terminating node). That is,
it returns a pointer to the last meaninful node in a DEVICE_PATH.
- efi_devpath_trim() generates a new DEVICE_PATH from an existing
DEVICE_PATH. The new DEVICE_PATH does not include the last
non-terminating node in the original path. If the original DEVICE_PATH
only contains the terminating node, this function returns NULL.
The caller is responsible for freeing the returned DEVICE_PATH via
free().
- efi_devpath_handle() attempts to find a handle that corresponds to a
given device path. However, if nodes at the end of the device path do
not have valid handles associated with them, this function will return
a handle that matches a node earlier in the device path. In particular,
this function returns a handle for the node closest to the end of the
device path which has a valid handle.
