After digging through more carefully, it looks like there's
no real need to have the DTB in the module directory.
So we can simplify a lot: Just copy DTB into local heap
for "fdt addr" and U-Boot integration, drop all the extra
COPYIN() calls.
I've left one final COPYIN() to update the in-kernel DTB
for consistency with how this code used to work, but I'm
no longer convinced it's appropriate here.
I've also remove the mem_load_raw() utility that I added
to boot/common/module.c with r247045 since it's no longer
necessary.
initialized after FPIO controller since they might rely on GPIO
functionality
- Update interrupts property of dma node to contain all allocated
interrupts
This was broken by r247045 which tried to copy the FDT into the
module directory immediately.
Instead, store the address and arrange for the FDT to get
copied into the module directory later when the usual
FDT initialization runs.
machine/signal.h and machine/ucontext.h into common x86 includes,
copying from amd64 and merging with i386.
Kernel-only compat definitions are kept in the i386/include/sigframe.h
and i386/include/signal.h, to reduce amd64 kernel namespace pollution.
The amd64 compat uses its own definitions so far.
The _MACHINE_ELF_WANT_32BIT definition is to allow the
sys/boot/userboot/userboot/elf32_freebsd.c to use i386 ELF definitions
on the amd64 compile host. The same hack could be usefully abused by
other code too.
When initializing the fdt, query U-Boot as well.
With this change, it is now feasible to have U-Boot load
the FDT, ubldr will pull it from U-Boot and hand it to the
kernel.
This will be used by some upcoming changes to loader(8) FDT
handling to allow it to use an FDT provided by an earlier
boot stage the same as an FDT loaded from disk.
so that simultaneous access cannot happen. Protect scratch area using
the enumeration lock. Also reduce stack usage in usbd_transfer_setup()
by moving some big stack members to the scratch area. This saves around
200 bytes of stack.

This adds support for version 10, revision 01, but it should also work
without changes for the 0901 model, at least until we get drivers for the
two different wifi chips involved.
Many users contributed to and tested the various patchsets floating around
for the past year that have eventually evolved into this checkin, most notably
Richard Neese who provided the bulk of the kernel config file.

comconsole setup. Previously the hint would be set when if you set a
custom port, but it would not be updated if you later set a custom speed.
Also, leave the hw.uart.console hint mutable so it can be overridden or
unset by the user if needed.

gcc handles -symbolic by passing -Bsymbolic through to ld. clang ignores
-symbolic and thus invokes ld without -Bsymbolic which leads to some symbols
not being properly linked in loader.efi. Fix this by using -Wl,-Bsymbolic which
passes -Bsymbolic to ld in both the gcc and clang cases.

arch_zfs_probe method is supposed to only probe for ZFS vdevs, but it can
not expect that ZFS data is in a ready state yet.
So, move some code from sparc64_zfs_probe to main to meet the constraints.

Bump up the heap size to 1MB. With a few kernel modules, libstand
zalloc and userboot seem to want to use ~600KB of heap space, which
results in a segfault when malloc fails in bhyveload.

r241153

Bump userboot's value up to 15000 cells.

Prior to r222417, setting `password' in loader.conf(5) did not prevent boot
but instead only prevented changes to boot options by prompting for password
if autoboot failed or the user interrupted the countdown sequence.
After r222417 the same machine with `password' set in loader.conf(5) would no
longer boot without _always_ entering the password.
This patch restores the old (8.x and older) functionality for password in
loader.conf(5) while adding a new bootlock_password feature to replace the
edge-case should anybody desire the regressed functionality (HINT: great for
PXE servers and/or private distributions).
loader.conf(5) was updated to be more clear with-respect to password setting
(previous text was misleading).
Documentation (loader.conf(5) and check-password.4th(8)) has been updated to
include notes on the new bootlock_password setting.
Special thanks to Alex Verbod for bringing this to my attention and helping to
refine the loader.conf(5) text.

- Add "fdt addr" subcommand that lets you specify preloaded blob address
- Do not pre-initialize blob for "fdt addr"
- Do not try to load dtb every time fdt subcommand is issued,
do it only once
- Change the way DTB is passed to kernel. With introduction of "fdt addr"
actual blob address can be not virtual but physical or reside in
area higher then 64Mb. ubldr should create copy of it in kernel area
and pass pointer to this newly allocated buffer which is guaranteed to work
in kernel after switching on MMU.
- Convert memreserv FDT info to "memreserv" property of root node
FDT uses /memreserve/ data to notify OS about reserved memory areas.
Technically it's not real property, it's just data blob, sequence
of <start, size> pairs where both start and size are 64-bit integers.
It doesn't fit nicely with OF API we use in kernel, so in order to unify
thing ubldr converts this data to "memreserve" property using the same
format for addresses and sizes as /memory node.
