2628555d5f Move 'compatible' line out of the common am335x.dtsi and into
the beaglebone-specific .dts file.

Add a new .dts for the BeagleBone Black with more memory,
slightly different pinmux initialization, and with mmchs1
configured (though the latter doesn't quite work yet).

99eef68204 Move initialization of CESA decoding windows from common section
to driver specific files.

- window initialization is done during device attach
- CESA TDMA decoding windows values are set based on DTS,
 not copied from CPU registers
- remove unnecessary virtual mapping
- update dts file

dbfc29017c When rebooting (exiting) from the BTX loader, make sure to restore the
GDT from the correct segment, otherwise a triple fault would be caused.
In some virtual environments (VMware, VirtualBox, etc) this could lead
to a unhandled error or hang in the guest emulation software.

Thanks to avg and jhb for a few hints in the right direction.

a58e544f50 The CELL fields can be various integer types depending on the platform
(ARM uses 'int' and 'unsigned'; i386 uses 'long' and 'unsigned long'),
so we need explicit casts to long and unsigned long here to ensure
that the result matches the printf %ld and %lx specifiers.

7554e820bb 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.

dd9b8b36dd 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.

6d4a620eba 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.

3bb97cef07 "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.

31a53cd036 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.

f87223581e 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.

ecfc48a031 Add support for the GlobalScale Technologies DreamPlug computer.
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.

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

5660634004 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.
