My change had good intentions, but the implementation was incorrect:
- printf was returning the number of characters in the format string
plus the NUL, but failed in two regards implementation wise:
-- the pathological case, printf(""), wasn't being handled properly since
the pointer is always incremented, so the value returned would be
off-by-one.
-- printf(3) reports the number of characters printed post-conversion via
vfprintf, etc.
- putchar(3) should return the character printed or EOF, not the number
of characters output to the screen.
My goal in making the change (again) was to increase parity, but as bde
pointed out these are freestanding functions, so they don't have to
conform to libc/POSIX. I argued that the functions should be named
differently since the implementation is different enough to warrant it
and to allow boot2 code to be usable when linked against sys/boot and
libstand and other libraries in base. I have no interest in pushing
this change forward more though, as the original concern I had behind
the change with zfsboottest was resolved in r321849 and r321852. The
next person that updates the toolchain gets to deal with the
inconsistency if it's flagged by a newer compiler.

Both printf and putchar return int, not void.
This will allow code that leverages the libcalls and checks/rely on the

By default LLD links with relocations disallowed against readonly
sections (e.g., .text), but the 32-bit ARM EFI & uboot boot bits require
such relocations. -znotext is either ignored as an unknown -z option
(in-tree lld 2.17.50) or is already the default (GNU ld or GNU gold from
ports) so we can just add it unconditionally to allow building with LLD.
This is similar to the change in r320179 for the kernel link.

Implement simple chain loader in loader; this update does add chain command,
taking device or file as argument to load and start new boot loader.
In case of BIOS, the chain will read the boot block to address 0000:7c00 and
jumps on it. In case of UEFI, the chain command is to be used with efi
application, typically stored in EFI System Partition.
The update also does add simple menu entry, if the variable chain_disk is set.
The value of the variable chain_disk is used as argument for chain loading.

While it sounds like a good idea to extract the RFC1048 data from PXE, in the
end it is not and it is causing lots of issues. Our pxeloader might need
options which are incompatible with other pxe servers (for example iPXE, but
not only).
Our pxe loaders are also now settings their own user class, so it is useful to

The current read from network is working from up to down - we have some
protocol needing the data from the network, so we build the buffer space
for that protocol, add the extra space for headers and pass this buffer
down to be filled by nif get call in hope, we have guessed the incoming
packet size right. Amazingly enough this approach mostly does work, but
not always...
So, this update does work from down to up - we allocate buffer (based
on MTU or frame size info), fill it up, and pass on for upper layers.
The obvious problem is that when we should free the buffer - if at all.
In the current implementation the upper layer will free the packet on error
or when the packet is no longer needed.
While working on the issue, the additional issue did pop up - the bios
implementation does not have generic get/put interface but is using pxe
udpsend/udpreceive instead. So the udp calls are gone and undi interface
is implemented instead. Which in turn means slight other changes as we
do not need to have duplicated pxe implementation and can just use dev_net.
To align packet content, the actual read from nic is using shifted buffer by
ETHER_ALIGN (2).

gptzfsboot: error 1 lba 1
gptzfsboot: no ZFS pools located, can't boot
The first two errors above are from issuing INT13 EAX=0x4800, meaning we
need to check if EDD is available and use EAX=0x800 if not.
For an workaround I'm using the similar idea as in biosdisk.c - first probe
ah=8h, then check if we have EDD.
Note we would like to see the correct disk size info, but we *may*
get away with anything >64MB, so we could at least test 2 zfs pool labels
on whole disk setup and not to freak out the INT13 interface.
If we get away with initial disk probing, then we have partition sizes from
the partition table and we should be able to complete the disk probing.
Note: this update does not provide full fix to all errors, but we get
the drvsize() errors removed.

Maintaining an address family and framework has real costs when we make

manufactured in the last 20 years and some will not even work in modern
motherboards (some newer devices that patm(4) could be updated to
support apparently exist, but we do not currently have support).
With this change, support remains for some netgraph modules that don't
require NATM support code. It is unclear if all these should remain,
though ng_atmllc certainly stands alone.
Note well: FreeBSD 11 supports NATM and will continue to do so until at
