Fix EHCI driver by excluding first 512K from available memory

On Zynq 256K-512K memory region is not accessible by all bus masters.
EHCI driver fails when trying to use it for DMA transfers. Patching
memory node does not help because ubldr overrides values there with
the ones obtained from u-boot. So as a workaround we just mark first
512K as reserved.

Split CESA memory resource into TDMA and CESA regs

TDMA and CESA registers are placed in different ranges of memory. Split
memory resource in DTS to reflect that. This change is needed to support
multiple CESA nodes as otherwise the ranges of different nodes would
overlap.

In consequence, CESA_WRITE and CESA_READ macros have been split depending
on which range of registers is accessed. Offsets for CESA registers have
been modified as the base address has changed.

Add proper PCIe init for MT7628/MT7688 SoCs

However, LEDE (and OpenWRT) dts files have the PCIe node for MT7628/MT7688

Add FDT overlays support to ubldr

FDT overlays is de-facto standard for describing expansion boards like
Beaglebone capes or Raspberry Pi shields. The ides is to have basic
DTB for base board and overlays DTB for shields/capes and to construct
final DTB either using human-readable configuration or some
self-discovery mechanism. I believe this approach can also be expanded
to support dynamically loadable FPGA bitstreams on systems like
Zedboard/Zybo.

Overlaying process is simmilar to executable link process for
binaries: each DTB has "exported" symbols and "undefined" symbols, the
latter are resolved using information for the former obtained from
base DTB or one of the overlays applied earlier (more rare case).

This symbols information is not generated by standard dtc that FreeBSD
has in base system, patched[1] version required to produces
overlay-compatible blobs. So although DTB files generated by
buildkernel do not support overlays there are enough
vendor/community-provided DTB blobs ciruclating around to justify
committing this change to ubldr.

This commit introduces handler for "fdt_overlays" variable that can be
defined either as a loader env variable or U-Boot env variable.
fdt_overlays is comma-separated list of .dtbo files located in
/boot/dtb/ directory along with base .dtb. ubldr loads files and
applies them one-by-one to base .dtb and then passes result blob to
the kernel.

Import Mediatek/Ralink dtsi patches against OpenWRT dtsi files

This revision suggests dtsi patches to be used with the original OpenWRT
dtsi files so we can re-use what has already been done in OpenWRT for the
Mediatek/Ralink SoCs.

The only thing that is required after importing this revision should be
the following:
1. Import OpenWRT dts/dtsi files into sys/gnu/dts/mips
2. Run the following script in sys/gnu/dts/mips:
for f in `ls [mr]t*.dtsi`; do
printf "\n#include <fbsd-$f>\n" > $f
done

This will apply our dtsi patches to OpenWRT's dtsi files and will allow us
to re-use dts/dtsi files for ~170 Mediatek/Ralink boards.

Currently our drivers are not 100% compatible with OpenWRT's dts files, but
they're compatible enough.
We can add more functionality in the future that would better leverage the
OpenWRT work as well.

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

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

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.

Add a feature for automatically finding and loading a dtb file by name.
The name is taken from the u-boot env vars fdtfile or fdt_file. If the
name isn't fully-qualified a search is done in module_path locations.

The search order for a usable dtb in fdt_setup_fdtp() is now

- A dtb loaded with an explicit "load -t dtb" command.
- A dtb already loaded into memory somehow[*] and pointed to by fdt_to_load.
- A dtb in the memory pointed to by the u-boot env vars fdtaddr or fdt_addr.
- A file named by the u-boot env vars fdtfile or fdt_file.
- A static dtb compiled into the kernel.

* Presumably by some arch-specific command or code.

Change fdt_setup_fdtp() from "guess then fail" to more probe-like behavior.

The old code basically said it was going to use some particular blob
without knowing whether it could successfully do so, then it would invoke
the function to do that and return its status. If it failed, you were
done, even if other blobs might be available. Now the code attempts to use
some particular blob and if that succeeds it says so and returns success,
otherwise it moves on to try another potential blob.

One specific problem this solves is when u-boot sets an fdtaddr variable
to point to some memory address, then doesn't actually load a blob at
that address. Now the header check will fail, and the code will move
on to the fallback dtb compiled into the kernel (if any).

Look for both fdtaddr and fdt_addr env var names. Grepping the u-boot
source shows that board vendors seem to be about evenly split on this.

This commit is a trivial change to note that while the previous change
was supposed to be whitespace only, this functional change also crept in.
The added lines were:

/* Board vendors use both fdtaddr and fdt_addr names. Grrrr. */

Add basic cpu frequency control and temperature monitoring to imx6_anatop.

The temperature monitor device is enabled to sample the die temperature at
16hz. The temperature is published via sysctl. A callout routine at 10hz
monitors the temperature and throttles back the cpu if the temperature
goes over a user-settable throttle point (by default 10C less than the
critical high-point temperature for the chip). The hardware is supposed
to be able to deliver an interrupt when the temperature exceeds a settable
limit, but the interrupt never arrives so for now a callout does the job.

At attach time we read the maximum cpu frequency the chip is allowed to run
at and the cpu is set to run at that speed. It's reported at attach time.
A sysctl variable reports the current speed when queried.

New sysctl values:

dev.imx6_anatop.0.cpu_mhz: 984
dev.imx6_anatop.0.temperature: 37.9C

TI sdhci driver improvements, mostly related to fdt data...

Use the published compatible strings (our own invention, "ti,mmchs" is
still accepted as well, for now).

Don't blindly turn on 8-bit bus mode, because even though the conroller
supports it, the board has to be wired appropriately as well. Use the
published property (bus-width=<n>) and honor all the valid values (1,4,8).

The eMMC device on a Beaglebone Black is wired for 8-bit, update the dts.

The mmchs controller can inherently do both 1.8v and 3.0v on the first
device and 1.8v only on other devices, unless an external transceiver is
used. Set the voltage automatically for the first device and honor
the published fdt property (ti,dualvolt) for other devices.

Thanks go to Ilya Bakulin for figuring out the voltage compatibility stuff.

Add dts source for imx6 SoCs and for Wandboard boards.

The imx6.dtsi is incomplete, but has enough to support devices that work
right now. Eventually it will need to be split into several files that
account for the differences between SoCs in the imx6 family.

The board config for Wandboard Dual is untested. Solo and Quad work, but
one one core is turned on for the quad right now (baby steps).

Rework the imx ehci driver so that it's four separate ehci units rather
than one unit with four busses attached to it. This allows us to use
existing fdt data which describes separate devices with separate resources.
It also allows any combination of the units to be en/disabled in the
board dts files.

Adjust our dts code to match what's used by linux and u-boot now that
we're structured to do so.

Document lots of interesting stuff learned whiling doing this with a big
comment block in the driver, so I don't have to re-learn it for the next
round of changes.

Add support for uarts other than the serial console in TI OMAP SoCs.

The TI uart hardware is ns16550-compatible, except that before it can
be used the clocks and power have to be enabled and a non-standard
mode control register has to be set to put the device in uart mode
(as opposed to irDa or other serial protocols). This adds the extra
code in an extension to the standard ns8250 probe routine, and the
rest of the driver is just the standard ns8250 code.

Make the standard sdhci(4) driver work for the TI OMAP family SoCs.
The MMCHS hardware is pretty much a standard SDHCI v2.0 controller with a
couple quirks, which are now supported by sdhci(4) as of r254507.

This should work for all TI SoCs that use the MMCHS hardware, but it has
only been tested on AM335x right now, so this enables it on those platforms
but leaves the existing ti_mmchs driver in place for other OMAP variants
until they can be tested.

This initial incarnation lacks DMA support (coming soon). Even without it
this improves performance pretty noticibly over the ti_mmchs driver,
primarily because it now does multiblock IO.

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.

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.

- Move dma, sdhci and mbox nodes down in dts in order to get them
initialized after FPIO controller since they might rely on GPIO
functionality

- Update interrupts property of dma node to contain all allocated
interrupts

"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.

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
the FDT, ubldr will pull it from U-Boot and hand it to the
kernel.

- Do not pre-initialize blob for "fdt addr"
- Do not try to load dtb every time fdt subcommand is issued,
do it only once
- Change the way DTB is passed to kernel. With introduction of "fdt addr"
actual blob address can be not virtual but physical or reside in
area higher then 64Mb. ubldr should create copy of it in kernel area
and pass pointer to this newly allocated buffer which is guaranteed to work
in kernel after switching on MMU.
- Convert memreserv FDT info to "memreserv" property of root node
FDT uses /memreserve/ data to notify OS about reserved memory areas.
Technically it's not real property, it's just data blob, sequence
of <start, size> pairs where both start and size are 64-bit integers.
It doesn't fit nicely with OF API we use in kernel, so in order to unify
thing ubldr converts this data to "memreserve" property using the same
format for addresses and sizes as /memory node.

Access the device tree blob via copyin/copyout.

The code previously assumed that copyin/copyout did no
address translation and that the device tree blob could
be manipulated in-place (with only a few adjustments for
the ELF loader offset). This isn't possible on all platforms,
so the revised code uses copyout() to copy the device tree
blob into a heap-allocated buffer and then updates the
device tree with copyout(). This isn't ideal, since it
bloats the loader memory usage, but seems the only feasible
approach (short of rewriting all of the fdt manipulation
routines).

Don't hang if there is no /cpus node in the device tree.
