the PowerPC port with all the Open Firmware bits removed and replaced by
their EFI counterparts. On the whole, I think I prefer Open Firmware.
This code is supposed to be an immutable shim that sits on the EFI system
partition, loads /boot/loader.efi from UFS and tells the real loader what
disk/partition to look at. It finds the UFS root partition by the somewhat
braindead approach of picking the first UFS partition it can find. Better
approaches are called for, but this works for now. This shim loader will
also be useful for secure boot in the future, which will require some
rearchitecture.
Previously ${COMPILER_TYPE} was checked in sys/boot/amd64, and the efi
subdirectory was skipped altogether for gcc (since GCC does not support
a required attribute). However, during the early buildworld stages
${COMPILER_TYPE} is the existing system compiler (i.e., gcc on 9.x build
hosts), not the compiler that will eventually be used. This caused
"make obj" to skip the efi subdirectory. In later build stages
${COMPILER_TYPE} is "clang", and then the efi loader would attempt to
build in the source directory.

The UEFI loader causes buildworld to fail when building with (in-tree)
GCC, due to a typedef redefinition. As it happens the in-tree GCC
cannot successfully build the UEFI loader anyhow, as it does not support
__attribute__((ms_abi)). Thus, just avoid trying to build it with GCC, rather than disconnecting it from the build until the underlying issue
is fixed.

Specific revisions of note from projects/uefi:
r247380:
Adjust our load device when we boot from CD under UEFI.
The process for booting from a CD under UEFI involves adding a FAT
filesystem containing your loader code as an El Torito boot image.
When UEFI detects this, it provides a block IO instance that points at
the FAT filesystem as a child of the device that represents the CD
itself. The problem being that the CD device is flagged as a "raw
device" while the boot image is flagged as a "logical partition". The
existing EFI partition code only looks for logical partitions and so
the CD filesystem was rendered invisible.
To fix this, check the type of each block IO device. If it's found to
be a CD, and thus an El Torito boot image, look up its parent device
and add that instead so that the loader will then load the kernel from
the CD filesystem. This is done by using the handle for the boot
filesystem as an alias.
Something similar to this will be required for booting from other
media as well as the loader will live in the EFI system partition, not
on the partition containing the kernel.
r246231:
Add necessary code to hand off from loader to an amd64 kernel.
r246335:
Grab the EFI memory map and store it as module metadata on the kernel.
This is the same approach used to provide the BIOS SMAP to the kernel.
r246336:
Pass the ACPI table metadata via hints so the kernel ACPI code can
find them.
r246608:
Rework copy routines to ensure we always use memory allocated via EFI.
The previous code assumed it could copy wherever it liked. This is not
the case. The approach taken by this code is pretty ham-fisted in that
it simply allocates a large (32MB) buffer area and stages into that,
then copies the whole area into place when it's time to execute. A more
elegant solution could be used but this works for now.
r247214:
Fix a number of problems preventing proper handover to the kernel.
There were two issues at play here. Firstly, there was nothing
preventing UEFI from placing the loader code above 1GB in RAM. This
meant that when we switched in the page tables the kernel expects to
be running on, we are suddenly unmapped and things no longer work. We
solve this by making our trampoline code not dependent on being at any
given position and simply copying it to a "safe" location before
calling it.
Secondly, UEFI could allocate our stack wherever it wants. As it
happened on my PC, that was right where I was copying the kernel to.
This did not cause happiness. The solution to this was to also switch
to a temporary stack in a safe location before performing the final
copy of the loaded kernel.

arguments from type,filename to filename,type to be consistant with other
public file_whatever() functions, and change it to return a pointer to
the preloaded_file struct describing the file. Adjust existing callers.
The old code basically said it was going to use some particular blob
without knowing whether it could successfully do so, then it would invoke
the function to do that and return its status. If it failed, you were
done, even if other blobs might be available. Now the code attempts to use
some particular blob and if that succeeds it says so and returns success,
otherwise it moves on to try another potential blob.
One specific problem this solves is when u-boot sets an fdtaddr variable
to point to some memory address, then doesn't actually load a blob at
that address. Now the header check will fail, and the code will move
on to the fallback dtb compiled into the kernel (if any).
If a "loaderdev=<device>" env variable is set and the named device
exists, it is used. If the device doesn't exist, fall back to the
historic "probe" loop that prefers disk devices over network devices.
If the env var is not set, preserve the historic behavior of using the
first working disk device provided by u-boot, or a network device if no
functional disk device is found and a network device exists.
The old probe loop is reworked so that it checks all bootable devices
provided by u-boot rather than taking an early-out on the first device
found. This results in the cosmetic change of listing all potential boot
devices for the user, but the behavior of which device it chooses is the
same as it has always been.

The temperature monitor device is enabled to sample the die temperature at
16hz. The temperature is published via sysctl. A callout routine at 10hz
monitors the temperature and throttles back the cpu if the temperature
goes over a user-settable throttle point (by default 10C less than the
critical high-point temperature for the chip). The hardware is supposed
to be able to deliver an interrupt when the temperature exceeds a settable
limit, but the interrupt never arrives so for now a callout does the job.
At attach time we read the maximum cpu frequency the chip is allowed to run
at and the cpu is set to run at that speed. It's reported at attach time.
