b829c841ad loader: fix the size of MODINFOMD_MODULEP
The data in MODINFOMD_MODULEP is packed by the loader as a 4 byte type, but
the amd64 kernel expects a vm_paddr_t, which is of size 8 bytes. Fix this by
saving it as 8 bytes in the loader and retrieving it using the proper type
in the kernel.

df560e4e96 loader: use correct types for parse_modmetadata
Use the proper types in parse_modmetadata for the p_start and p_end
parameters. This was causing problems in the ARM 32bit loader.

ca49b3342d loader: implement multiboot support for Xen Dom0
Implement a subset of the multiboot specification in order to boot Xen
and a FreeBSD Dom0 from the FreeBSD bootloader. This multiboot
implementation is tailored to boot Xen and FreeBSD Dom0, and it will
most surely fail to boot any other multiboot compilant kernel.

In order to detect and boot the Xen microkernel, two new file formats
are added to the bootloader, multiboot and multiboot_obj. Multiboot
support must be tested before regular ELF support, since Xen is a
multiboot kernel that also uses ELF. After a multiboot kernel is
detected, all the other loaded kernels/modules are parsed by the
multiboot_obj format.

The layout of the loaded objects in memory is the following; first the
Xen kernel is loaded as a 32bit ELF into memory (Xen will switch to
long mode by itself), after that the FreeBSD kernel is loaded as a RAW
file (Xen will parse and load it using it's internal ELF loader), and
finally the metadata and the modules are loaded using the native
FreeBSD way. After everything is loaded we jump into Xen's entry point
using a small trampoline. The order of the multiboot modules passed to
Xen is the following, the first module is the RAW FreeBSD kernel, and
the second module is the metadata and the FreeBSD modules.

Since Xen will relocate the memory position of the second
multiboot module (the one that contains the metadata and native
FreeBSD modules), we need to stash the original modulep address inside
of the metadata itself in order to recalculate its position once
booted. This also means the metadata must come before the loaded
modules, so after loading the FreeBSD kernel a portion of memory is
reserved in order to place the metadata before booting.

In order to tell the loader to boot Xen and then the FreeBSD kernel the
following has to be added to the /boot/loader.conf file:

xen_cmdline="dom0_mem=1024M dom0_max_vcpus=2 dom0pvh=1 console=com1,vga"
xen_kernel="/boot/xen"

The first argument contains the command line that will be passed to the Xen
kernel, while the second argument is the path to the Xen kernel itself. This
can also be done manually from the loader command line, by for example
typing the following set of commands:

OK unload
OK load /boot/xen dom0_mem=1024M dom0_max_vcpus=2 dom0pvh=1 console=com1,vga
OK load kernel
OK load zfs
OK load if_tap
OK load ...
OK boot

b03747e983 Reserve and ignore the a new module metadata type MDT_PNP_INFO for
associating an optional PNP hint table with this module. In the
future, when these are added, these changes will silently ignore the
new type they would otherwise warn about. It will always be safe to
ignore this data. Get this into the builds today for some future
proofing.

2566c5264a Add support to turn off Beaglebone with poweroff(8) or shutdown(8) -p.
To cut off the power we need to start the shutdown sequence by writing
the OFF bit on PMIC.

Once the PMIC is programmed the SoC needs to toggle the PMIC_PWR_ENABLE
pin when it is ready for the PMIC to cut off the power.  This is done by
triggering the ALARM2 interrupt on SoC RTC.

The RTC driver only works in power management mode which means it won't
provide any kind of time keeping functionality.  It only implements a way
to trigger the ALARM2 interrupt when requested.

elsewhere.

Netboot support is missing for now and will be added in a future commit,
at which time loader.ps3 will be garbage collected.

0d203a6065 Create a custom /boot/defaults/loader.conf for ARM. This differs from the
standard file in the following ways:

 - modules_path includes /boot/dtb
 - It doesn't contain 533 lines, of which 500 are either commented out,
   empty, or something_which_doesnt_work_on_arm_anyway=NO

The standard defaults file takes 40+ seconds to process on an arm beaglebone
board.  This one takes just a couple seconds.

This gets installed instead of the original because of the .PATH magic in
the makefile.

3681c8d718 Add interrupt support for GPIO pins on OMAP4 and AM335x.
This enables the use of GPIO pins as interrupt sources for kernel devices
directly attached to gpiobus (userland notification will be added soon).

The use of gpio interrupts for other kernel devices will be possible when
intrng is complete.

All GPIO pins can be set to trigger on:

- active-low;
- active-high;
- rising edge;
- falling edge.

According to objcopy(1) --target is for use where the input and output
formats are the same ("no translation"). In practice it does detect the
input format in any case, but be explicit that we're specifying the
output format as we are translating from ELF to EFI PE format.
