When building some of the boot loaders with clang, and DEBUG_FLAGS or
CFLAGS having '-g' in it, clang outputs several assembly directives that
are too new for our version of binutils.
Therefore, assemble the resulting .s files with clang instead. A more
general solution can be implemented when a GNU as-compatible driver for
clang's integrated assembler appears.

contains one. Published dts source often includes a minimal default
memory definition and expects it to be overridden by the bootloader after
determining the actual physical memory in the system.
Motivation is to introduce BIOS specific quirks early in the boot
process. smbios_match can be called before malloc is avaible, that's
why parts of smbios_detect have been moved into a separate function
smbios_probe that will be called by smbios_detect as well as
smbios_match.

In UEFI it appears all available NICS are present to pass network traffic.
This gives the capability to load the loader.efi from disk then set
currdev="net3:" and then all I/O will over over the 2nd NIC. On this
machine is appears the first handle is the first NIC in IPv4 mode and
then the 2nd handle is the first NIC in IPv6 mode. The 3rd handle is
the 2nd NIC in IPv4 mode. The fix is to index into the handle based
on the unit cached from boot device passed into the loader.
Some testing info from a test boot via kenv:
currdev="net3:"
loaddev="net3:"

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.

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

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.

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.
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.

effectively disables the animation completely.
