9639a6c7c9 Rename a10_emac_gpio_config() to a10_gpio_ethernet_activate() to make the
change to GMAC easier on A20 SoCs.

On A10 only the EMAC controller is available (fast ethernet), but on A20
there is also GMAC a high (or better) performant controller (gigabit
ethernet).

On A20 the both controllers uses the same pins to talk to the ethernet PHY
(MII or RGMII) and they can be selected by the GPIO pin mux.

There is work in progress to bring in GMAC support.

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).

5ee00411e4 Add DMA support for Allwinner MMC controller.
DMA handles all data transfers up to 128K or 16 segments and fallback to
pio mode when DMA requirements are not met.

The read performance has improved greatly while the write performance also
showed some improvement but seems limited by the card type and quality.

- 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

617994efc7 Add basic support for ACPI. It splits out the nexus driver to two new
drivers, one for fdt, one for acpi. It then uses this to decide if it will
use fdt or acpi.

The GICv2 (interrupt controller) and Generic Timer drivers have been
updated to handle both cases.

As this is early code we still need FDT to find the kernel console, and
some parts are still missing, including PCI support.

4ea6a9a28f Generalised support for copy-on-write structures shared by threads.
Thread credentials are maintained as follows: each thread has a pointer to
creds and a reference on them. The pointer is compared with proc's creds on
userspace<->kernel boundary and updated if needed.

This patch introduces a counter which can be compared instead, so that more
structures can use this scheme without adding more comparisons on the boundary.

   "4.15V", "4.20V" and "4.25V".

defines into bitmap structures.

Also threat the case when power source is neither "AC" nor "USB"
as "Battery", not "Unknown".

The current FreeBSD driver doesn't program the video

for the frame buffer to be useful (otherwise it can
be skipped).

e81032ad24 Fix a lock up where we enter swapper() with interrupts disabled.
In smp_rendezvous_cpus we expect to wait for all cpus to enter
smp_rendezvous_action. If we call this holding a proc lock swapper may
attempt to also lock it, however as interrupts are disabled the cpu never
handles the ipi. Because smp_rendezvous_action waits for all signaled
cpus before contining it may get caught waiting for the cpu running swapper
as the proc mutex will be unlocked after smp_rendezvous_cpus finishes.

The fix is to enable interrupts in the configure stage as we should be
doing.

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

This fixes an issue where the struct may not be correctly aligned on the
stack in the syscall function. This may lead to accesing a 64-bit value
at a non 64-bit. This will raise an exception and panic the kernel.

We have been lucky where on arm and armv6 both clang and gcc correctly

when loader(8) passed physical addresses in loader metadata for arm, but
that is no longer true; all metadata has already been adjusted to vitual

I can't track down the exact revision in loader where a change from physical
to virtual metadata addresses happened.  The code involved is very twisty
and complicated.  I suspect the change was an unintended consequence of the

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).

a8a4800fff Add assertions that the addresses passed to tlb maintenance are page-aligned.
Perform cache writebacks and invalidations in the correct (inner to outer
or vice versa) order, and add comments that explain that.

Consistantly use 'va' as the variable name for virtual addresses.

For consistency with the naming conventions used by the other
implementations kill armv7_sleep and keep armv7_cpu_sleep.

ee0f1e8e43 Fix the vmstat -i output on ARM.
The consumers of hw.intrnames expect a NULL byte at end of the string
containing the interrupt names.

On ARM all the interrupt name slots are initialized and this leave no room
for the terminating NULL byte, which makes vmstat read beyond the end of
intrnames.

dfb378345f Retire pmap_lazyfix(). This function only existed in the new armv6 pmap
because the i386 pmap on which the new armv6 pmap is based had it, and in

ae4fa2223a Add the kernel support for Thumb-2. It is only supported on ARMv7 as the
main ARMv6 target, the Raspberry Pi, doesn't support Thumb-2.

This as been tested with a Thumb-2 userland, however building one is
currently unsupported as there are known toolchain issues breaking some
binaries. Further work will also be needed to decide on the method of
selecting which instruction set to build for, and to benchmark both to
find how building everything as Thumb-2 will affect performance.

88feae84be Merge ^/projects/release-arm-redux into ^/head.
Of note:

- This commit adds native FreeBSD/arm release build support without
  requiring out-of-tree utilities.

- Part of this merge removes the WANDBOARD-{SOLO,DUAL,QUAD} kernel
  configuration files, for which the IMX6 kernel configuration file
  should be used instead.

- The resulting images have a 'freebsd' user (password 'freebsd'),
  to allow ssh(1) access when console access is not available (VGA
  or serial).  The default 'root' user password is set to 'root'.

- The /etc/ttys file for arm images now enable both ttyv0 and ttyu0
  by default.
