It was written basing on:
TCG PC Client Platform TPM Profile (PTP) Specification Version 22, Revision 1.03.
It only supports Locality 0. Interrupts are only supported in FIFO mode.
The driver in FIFO mode was tested on x86 with Infineon SLB9665 discrete TPM chip.
Driver in both modes was also tested on qemu with swtpm running on host.

This fix booting on A64 boards when disabling the unused regulators at boot.
We did disable all the regulator handled by register 0x13 which of course contain
mandatory regulators for the board to be up.

capable IOs. NVME specification supports specific type of scatter gather list
called as PRP (Physical Region Page) for IO data buffers. Since NVME drive is
connected behind SAS3.5 tri-mode adapter, MegaRAID driver/firmware has to convert
OS SGLs in native NVMe PRP format. For IOs sent to firmware, MegaRAID firmware
does this job of OS SGLs to PRP translation and send PRPs to backend NVME device.
For fastpath IOs, driver will do this OS SGLs to PRP translation.

required Write IOs as Fast Path IOs (after the appropriate checks
allowing Fast Path to be used) to the appropriate physical drives
(translated from the OS logical IO) and wait for all Write IOs to complete.
Design: A write IO on RAID volume will be examined if it can be sent in
Fast Path based on IO size and starting LBA and ending LBA falling on to
a Physical Drive boundary. If the underlying RAID volume is a RAID 1/10,
driver issues two fast path write IOs one for each corresponding physical
drive after computing the corresponding start LBA for each physical drive.
Both write IOs will have the same payload and are posted to HW such that
replies land in the same reply queue.
If there are no resources available for sending two IOs, driver will send
the original IO from upper layer to RAID volume through the Firmware.
When both IOs are completed by HW, the resources will be released
and SCSI IO completion handler will be called.

stream to help HBA Firmware do the Full Stripe Writes. For read IOs on
certain RAID volumes like Read Ahead volumes,this will help driver to
send it to Firmware even if the IOs can potentially be sent to
hardware directly (called fast path) bypassing firmware.
Design: 8 streams are maintained per RAID volume as per the combined
firmware/driver design. When there is no stream detected the LRU stream
is used for next potential stream and LRU/MRU map is updated to make this
as MRU stream. Every time a stream is detected the MRU map
is updated to make the current stream as MRU stream.

With the default Qemu parameters, only 128MB RAM gets given to a VM. This causes
the loader to be unable to allocate the 64MB it needs for the heap. This change
makes the cause of the error more obvious.

In the nda(4) driver, only set DISKFLAG_CANDELETE (a.k.a. can support
BIO_DELETE) if the drive supports Dataset Management. There are reports
that without this check, VMWare Workstation does not work reliably.
Fix is to check the ONCS field in the NVMe Controller Data structure for
support. This check previously existed but did not survive the
big-endian changes.

Previous commits have made VM_MIN_KERNEL_ADDRESS its own separate entity,
and rebased the kernel around that address instead of KERNBASE. This commit
pulls the trigger to rebase KERNBASE to a physical load address. The
eventual goal is to align the address with the AIM KERNBASE, but at this
time that's not an option.
Currently a Book-E kernel must be loaded on a 64MB boundary, due to size
issues. The common load address is at the 64MB mark (0x04000000), so simply
make that the default KERNBASE.
As of this commit, Book-E kernels can be loaded and booted with ubldr.

Optimize the exception handler to only save and load the upper word of the
GPRs used in the emulating instruction. This reduces the save/load
overhead, and as a side effect does not overwrite the upper word of any
temporary register.

Right now, aesni_cipher_alloc does a bit of special-casing
for CRYPTO_F_IOV, to not do any allocation if the first uio
is large enough for the requested size. While working on ZFS
crypto port, I ran into horrible performance because the code
uses scatter-gather, and many of the times the data to encrypt
was in the second entry. This code looks through the list, and
tries to see if there is a single uio that can contain the
requested data, and, if so, uses that.
This has a slight impact on the current consumers, in that the
check is a little more complicated for the ones that use
CRYPTO_F_IOV -- but none of them meet the criteria for testing
more than one.

Since OpenSSL 1.1.1, the good old BSD-specific cryptodev engine has been
deprecated in favor of this new engine. However, this engine is not
throughly tested on FreeBSD because it was originally written for Linux.
http://cryptodev-linux.org/
Also, the author actually meant to enable it by default on BSD platforms but
he failed to do so because there was a bug in the Configure script.
https://github.com/openssl/openssl/pull/7882
Now they found that it was more generic issue.
https://github.com/openssl/openssl/pull/7885
Therefore, we need to enable this engine on head to give it more exposure.
