FICL definitions not in ficl/ficl32 files broke this generally. This
makes that stuff conditional on BOOT_FORTH. Also, move definitions
related to the architecture (FICL_CPUARCH and friends) into
Makefile.ficl that all parts of the tree that include files with ficl
need to include (but only if MK_FORTH == yes). In addition, had to fix
library ordering issue with LIBSTAND to keep it last. Without boot
forth, there's no references to memset to bring in memset.o from
libstand.a to satisfy libgeliboot.a's use of it. Listing libstand last
solves this issue (and it's the proper place for libstand to boot).
* On arm64 we need to use the ${MACHINE_CPUARCH} subdirectory.
* env.c is only needed when using forth so only build it there.

etc. can find out where the SMBIOS entry point is located. In pure
UEFI mode the BIOS is not mapped into the standard address space so the
SMBIOS table might not appear between 0xf0000 and 0xfffff. The
UEFI environment can report this the location of the anchor. If it is
reported then expose it as hint.smbios.0.mem. This can then be used
by other tools. However, we should make smbios(4) useful and have it
take this value and provide accesor function so ipmi(4) etc. don't
have to parse and figure things about the SMBIOS table. I have some
simple patches to smbios(4) to expose this address as sysctl and
for ipmi(4) to get the base address. However, the real fix is to
have ipmi(4) ask smbios(4) for what it wants and have smbios(4)
parse it out and return it. This would make smbios(4) useful and reduce
duplicated code. If this address doesn't point to the anchor then
finding SMBIOS info. will fail as if this didn't exist. So there should
be no harm.
With this change and the following hack, dmidecode works on a bunch of
UEFI machines that I tested:
if kenv hint.smbios.0.mem > /dev/null
then
mkdir -p /sys/firmware/efi
mount -t tmpfs -o size=8k tmpfs /sys/firmware/efi
echo "SMBIOS=`kenv hint.smbios.0.mem`" > /sys/firmware/efi/systab
fi
Linux exposes this information via the /sys/firmware/efi/systab file which
dmidecode looks at. We should update dmidecode to do this the FreeBSD
way when we determine what that is!

Some used int return instead of time_t. On some architectures the bit

There is no way to see anything about the faults occuring in
loader.efi. Some intel BIOSes do output a line into serial port at
115200/8/1 regardless of the current port settings with the EFI error
number, but this is too little, and not always available, esp. if the
user does not know where to look.
The patch adds a simple facility to grab exceptions and at least dump
generic registers and some exception details. Due to the relative
complexity of correctly taking over the BIOS IDT setup, only install
the facility on user request.
Two new commands, 'grab_faults' and 'ungrab_faults' are provided,
first one takes over, second undoes the first. It is supposed that
user would execute 'grab' by the developer direction of collecting the
debugging data. The 'fault' command generates exception to test the
setup.
Fault handlers use dedicated stack to improve chances of catching
stack/TSS exceptions. Due to this, BIOS IDT is duplicated into a
private copy, and debugger needs to find a free GDT slot for TSS. This
is done in somewhat complicated efi_redirect_exceptions().

Add a new 'netproto' variable which can be set for now to
NET_TFTP or NET_NFS (default to NET_NONE)
From the dhcp options if one sets the root-path option to:
"ip:path", the loader will consider it is booting over NFS
(meaning same behaviour as the default current behaviour)
if the dhcp option "tftp server address" is set (option 150)
the loader will consider it is booting over tftpfs, it will then
consider the root-path options with 2 possible case
1. "path" then the IP of the tftp server will be the one passed by
the option 150, and the files will be retrieved under "path" on the tftp
server
2. "ip:path" then the IP of the tftp server will be the one passed in
the option "overwritting the IP from the option 150.
We could not "abuse" the rootpath option in the form or tftp://ip:path because
this is already used for other purpose by iPXE preventing any chainload from
iPXE to the FreeBSD loader.
Given at each open(), the loader loops over all available filesystems and keep
the "best" error, we needed to prevent tftpfs to fallback on nfs and vice versa.
the tftpfs and nfs implementation in libstand now return EINVAL early if
'netproto' for that purpose.

Since loader itself is using 64MB memory for heap, updated zfsboot to

Note, adding additional features does increate zfsboot code, therefore
this update does increase zfsboot code to 128k, also I have ported gptldr.S

With this update, boot1.efi has almost reached the current limit of the size

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'.
