158c18ffb4 dd is currently a bootstrap tool. It really doesn't have any business
being a bootstrap tool. However, for reproducible build output,
FreeBSD added dd status=none because it was otherwise difficult to
suppress the status information, but retain any errors that might
happen. There's no real reason that dd has to be a build tool, other
than we use status=none unconditional. Remove dd from a bootstrap tool
entirely by only using status=none when available. This may also help
efforts to build the system on non-FreeBSD hosts as well.

3595d72f86 Disable loop unrolling in skein for sys/boot
When tsoome@ added skein support to the ZFS boot code and zfsloader, it
resulted in an explosion in code size, running close to a number of
limits.

The default for the C version of skein is to unroll all loops for
skein-256 and 512

Disabling the loop unrolling saves 20-28kb from each binary

2c55d0903d Add SHA512, skein, large blocks support for loader zfs.
Updated sha512 from illumos.
Using skein from freebsd crypto tree.
Since loader itself is using 64MB memory for heap, updated zfsboot to
use same, and this also allows to support zfs large blocks.

Note, adding additional features does increate zfsboot code, therefore
this update does increase zfsboot code to 128k, also I have ported gptldr.S
update to zfsldr.S to support 64k+ code.

With this update, boot1.efi has almost reached the current limit of the size
set for it, so one of the future patches for boot1.efi will need to
increase the limit.

Currently known missing zfs features in boot loader are edonr and gzip support.

6d51bbb52a boot/efi: Prefer nm to objdump
Both objdump and nm are equally capable of reporting undefined symbols.

This gets us a step closer to building without binutils as we have an nm
implementation from ELF Tool Chain.

7bd249ecf0 Add EFI ZFS boot support
This builds on the modular EFI loader support added r294060 adding a
module to provide ZFS boot support on EFI systems.

It should be noted that EFI uses a fixed size memory block for all
allocations performed by the loader so it may be necessary to tune this
size.

For example when building an image which uses mfs_root e.g. mfsbsd, adding
the following to /etc/make.conf would be needed to prevent EFI from running
out of memory when loading the mfs_root image.
EFI_STAGING_SIZE=128

445a2b570e Only build EFI components on supported compilers
As the in-tree GCC does not support __attribute__((ms_abi)) EFI can only
be built with Clang.

The EFI loader and boot1 validated this, but unused libefi was still built
causing issues under GCC after warnings where enabled by r293724.

Disable building all of EFI when the selected compiler is GCC.

022e692a47 Enable warnings in EFI boot code
Set WARNS if not set for EFI boot code and fix the issues highlighted by
setting it.

Most components are set to WARNS level 6 with few being left at lower
levels due to the amount of changes needed to fix at higher levels.

Error types fixed:
* Missing / invalid casts
* Missing inner structs
* Unused vars
* Missing static for internal only funcs
* Missing prototypes
* Alignment changes
* Use of uninitialised vars
* Unknown pragma (intrinsic)
* Missing types etc due to missing includes
* printf formatting types

ARM and i386 already required libstand so switch to using it for all

This is also a pre-cursor to enabling WARNS which highlighted a number

5b1c03fd13 The self-relocation code is not efi-specific, move it to boot/common.
The function was defined as taking 4 parameters and returning EFI_STATUS,
but all existing callers (in asm code) passed only two parameters and don't
use the return value. The function signature now matches that usage, and
doesn't refer to efi-specific types.

Parameters and variables now use the cannonical typenames set up by elf.h
(Elf_Word, Elf_Addr, etc) instead of raw C types. Hopefully this will
prevent suprises as new platforms come along and use this code.

The function was renamed from _reloc() to self_reloc() to emphasize its
difference from the other elf relocation code found in boot/common.
