These are declared as extern in a number of files (some with the wrong

declarations as well that are no longer used. No functional change.
Note: I've not tried to cope with the bi_load() functions which are the
same logical thing. These will be handled separately.

Both ofw_disk and ofw_net use the same parsedev routine, except for the
string passed in to match the ofw device node's type. Create a routine
to do that and connect these two users up to that.

Add a parsedev support for OpenFirmware disks. We must look at
characteristics of the OFW node to know if we match this device (so
supply a match routine) or not. Add a parsing routine to allocate
devdesc for OpenFirmware disks as well.

We need to match devices in a slightly special way: We have to look up

To support more flexible device matching, we now pass in the full
devspec to the parsedev routines. For everything execpt uboot, this is
just a drop in (since everything except uboot and openfirmware always
uses disk...: and/or zfs:, but openfirmware isn't really affected).
uboot we kludge around it by subtracting 4 from where the rest of the
device name starts. This is unforunate, and can compute the address one
before the string. But we never dereference that address. uboot needs
more work, and this is an acceptable UB until that other work happens.
OFW doesn't really use the parsedev routines these days (since none of
the supported device uses this... yet). It too needs more work, but it
needs device matching support first.

The rest of the code in the tree assumes that a DEVT_DISK uses a
disk_devdesc to represent the device. However ofw_disk diesn't, so we
can't use disk_fmtdev, nor disk_parsedev. ofw needs to have a
dv_match-like routine to use devpasrse, though, since we have two
drivers (net and block) that claim the same sort of devices (eg
/path/to/ofw-dev) based on the device-type property. In the interim, we
can't use devmatch and ofw_disk's and the default net driver's parsing
is offloaded ofw_parsedev.

We don't need to check if something is a ZFS device. Instead, if the

Change the first argument to zfs_parsedev() to be a pointer to a struct
devdesc *. This now gets filled in with a malloc'd structure that's
returned to the caller that the caller is repsonsible for freeing. Most
nplaces in the tree passed in a malloc'd pointer anyway, and this moves
knowledge of zfs_devdesc more firmly into the zfs.c code.

Fix boot1 and loader on PowerPC64 little-endian (LE).
Due to endian issues, boot1 couldn't find the UFS boot partition
and loader wasn't able to load the kernel. Most of the issues
happened because boot1 and loader were BE binaries trying to access
LE UFS partitions and because loader expects the kernel ELF image
to use the same endian as itself.
To fix these issues, boot1 and loader are now built as LE binaries
on PPC64LE. To support this, the functions that call OpenFirmware
were enhanced to correctly perform endian conversion on its input
and output arguments and to change the CPU into BE mode before
making the calls, as OpenFirmware always runs in BE. Besides that,
some other small fixes were needed.

Adjust a couple of printf() lines that deal with dumping out addresses
to cast to uintmax_t.
This allows building a 64-bit libofw for use in things like a future

Also, dmabuf appears to only be set for sparc64 case, but there was a

The vectx API, computes the hash for verifying a file as it is read.
This avoids the overhead of reading files twice - once to verify, then
again to load.
For doing an install via loader, avoiding the need to rewind
large files is critical.
This API is only used for modules, kernel and mdimage as these are the
biggest files read by the loader.
The reduction in boot time depends on how expensive the I/O is
on any given platform. On a fast VM we see 6% improvement.
For install via loader the first file to be verified is likely to be the
kernel, so some of the prep work (finding manifest etc) done by
verify_file() needs to be factored so it can be reused for
vectx_open().
For missing or unrecognized fingerprint entries, we fail
in vectx_open() unless verifying is disabled.
Otherwise fingerprint check happens in vectx_close() and
since this API is only used for files which must be verified
(VE_MUST) we panic if we get an incorrect hash.
