f370876f88 When running on armv6, set alignment checking to modulo-4 mode rather
than modulo-8, because clang emits ldrd and strd instructions for
addresses that are only 4-byte aligned

84fe418fcb Attach the elf section headers to the loaded kernel as metadata, so
they can easily be used by later post-processing.  When searching for
a compiled-in fdt blob, use the section headers to get the size and
location of the .dynsym section to do a symbol search.

This fixes a problem where the search could overshoot the symbol
table and wander into the string table.  Sometimes that was harmless
and sometimes it lead to spurious panic messages about an offset
bigger than the module size.

7323532fa2 Since ubldr doesn't necessarily load a kernel at the physical address in the
elf headers, mask out the high nibble of that address.  This effectly makes
the entry point the offset from the load address, and it gets adjusted for
the actual load address before jumping to it.

Masking the high nibble makes assumptions about memory layout that are true
for all the arm platforms we support right now, but it makes me uneasy.
This needs to be revisited.

59678235a8 Fix the bug I introduced in r247045.
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.

02ee499236 "fdt addr" gets run from loader.rc before the kernel is loaded.
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.

cda69c9622 Convert machine/elf.h, machine/frame.h, machine/sigframe.h,
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.

e341f5a967 Fix "fdt addr" to accept literal addresses rather than va offsets.
When initializing the fdt, query U-Boot as well.

With this change, it is now feasible to have U-Boot load

kernel.

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.

ef3e178ab5 Fix linking of loader.efi.
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.

  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

bde43ee183 Fix a regression caused by SVN r222417.
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.
