7ec8c789c3 Add AHCI attachment code for Allwinner A10/A20 SoCs.
The Allwinner SoC has an AHCI device on its internal main bus rather
than the PCI bus.  This SoC is somewhat underdocumented, and its SATA
controller is no exception.  The methods to support this chip were
harvested from the Linux Allwinner SDK, and then constants invented to
describe what's going on based on low-level constants contained in the
SATA standard and guess work.

This SoC requires a specific AHCI channel setup in order to start the
operations on the channel properly.

Clock setup and AHCI channel setup idea came from NetBSD.

Tested on Cubieboard 2 and Banana pi (and attachment on Cubieboard by
Pratik Singhal).

224fba2b43 Add HDMI support to Beaglebone Black:
- Add driver for TDA19988 HDMI framer
- Add simple interface to communicate with HDMI sink: read EDID and set videomode
- Add event-based API to notify LCD controller when HDMI sink is available
- Add HDMI framer node and add refernce to it to lcdc node. This part of
    DTS tree is custom and does not match Linux DTS because Linux uses
    combination of pseudo-node in DTS and hardcoded driver information
    that does not map to our model.

505050e877 Add kernel config and dts files for an aml8726-m3
based device.
Following u-boot commands allow FreeBSD boot on
Yiyate Android TV Box (aml8726-m3):

tv open 480p
mmc rescan 0
fatload mmc 0 0x80100000 kernel.bin
go 0x80100000

The current FreeBSD driver doesn't program the video
clocks so the u-boot tv command is necessary in order
for the frame buffer to be useful (otherwise it can
be skipped).

The SD card for the Yiyate Android TV Box doesn't need
anything special beyond creating a FAT16 and a UFS
filesystem.

5b03aba6c8 Switch TI platform support code from using FreeBSD's custom-baked DTS
files to vendor-provided ones. It should make easier to adopt platform
code to new revisions of hardware and to use DTS overlays for various
Beaglebone extensions (shields/capes).

Original dts filenames were not changed, they're now wrappers over dts
files provided by TI. So make sure you update .dtb files on your
devices as part of kernel update

GPIO addressing was changed: instead of one global /dev/gpioc0 there
are per-bank instances of /dev/gpiocX. Each bank has 32 pins so for
instance pin 121 on /dev/gpioc0 in old addressing scheme is now pin 25
on /dev/gpioc3

On Pandaboard serial console devices was changed from /dev/ttyu0 to
/dev/ttyu2 so you'll have to update /etc/ttys to get login prompt
on serial port in multiuser mode. Single user mode serial console
should work as-is

6a11fa4e31 Add the MMC/SD driver for Allwinner SoCs.
This is based on the patch sent by Alexander Fedorov with the following
fixes/improvements:

 - Better error handling;
 - Clock is derived from PLL6 (obtained from netbsd);
 - No more unnecessary busy loops on interrupt handler;
 - style(9) fixes and code cleanup.

I also want to thanks Martin Galvan who has sent an alternative
implementation with some interesting fixes.

Tested on CubieBoard2, Banana-Pi (thanks to netgate!) and Cubieboard1
(Pratik Singhal).

This is intended to pave the way for the upcoming GSoC work (and make
easier the build of images for the supported boards).

4d892e4f22 Introduce support for the Alpine PoC from Annapurna Labs
The Alpine Platform-On-Chip offers multicore processing
(quad ARM Cortex-A15), 1/10Gb Ethernet, SATA 3, PCI-E 3,
DMA engines, Virtualization, Advanced Power Management and other.

This code drop involves basic platform support including:
SMP, IRQs, SerDes, SATA. As of now it is missing the PCIe support.
Part of the functionality is provided by the low-level code (HAL)
delivered by the chip vendor (Annapurna Labs) and is a subject to
change in the future (is planned to be moved to sys/contrib directory).

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

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.
