Unbreak BCM2835/RPI-B support by bringing it in line with stable/11 and
head:

- Optimise reading of pending interrupt registers.

- Fix a bug where some DTS layouts could cause the premature ending of the
search (i.e. without returning any result) and you would end up with a
random MAC address.

- Reduce the diff between head and arm_intrng with the bcm2835 interrupt
controller.

- Allow the retrieving of the reserved pins state.

- Add support to the bcm2835 mailbox driver to work before interrupts are
enabled. This will be needed to enable the power on devices early on in the
boot process.

- Add support for enabling the USB on the Raspberry Pi boards when it hasn't
been done by U-Boot. This allows the USB to work when we load the kernel
directly.

- Call config_intrhook_disestablish on failure of the bcm2835 fb and fbd intr
hooks. With this we can get through the boot even if these functions fail.

- Add the structures needed to get/set the power state. These can be used
when, for example, we boot without U-Boot and wish to enable USB, or to
suspend an unneeded device.

- Add a mask to match only the relative base address of BSC controllers.

- Move the code to set the device power to the bcm2835 mailbox driver so it
can be reused by other drivers.

- Add the SOC_BCM2835 and SOC_BCM2836 options for the arm kernel and add the
former to std.bcm2835.

- Add a helper function to read clock frequencies from videocore and use this
to get the default frequency of the sdhci device.

- Add partial support for the Raspberry Pi 2.

- Remove a debug #error from the bcm2835 sdhci driver.

- Fetch the SDHCI frequency from videocore (our prefered source) and only if
it fails, fetch the clock-frequency from DTB. If both methods fail, use the
hardcoded default.

- Pass the supplied buffer length instead of a fixed size.

- Add the routines to query and setup the framebuffer state using the
BCM2835_MBOX_CHAN_PROP channel. The old channel (BCM2835_MBOX_CHAN_FB)
seems deprecated on recent firmware versions and is causing a freeze on
RPi 2.

- Fix DMA on RPi 2. BCM2836 has a different base address for peripherals.

- Enable DMA for sdhci on RPi 2 (BCM2836).

- Add a missing wakeup when releasing ownership of the SPI hardware.

- Fix framebuffer compatibility with new RPi firmware.

- Refactor bcm2835_cpufreq to use bcm2835_mbox_property API.

- Fix the sc(4) framebuffer driver on RPi 2.

- Fix the vt(4) framebuffer driver on RPi 2.

- Remove unused mutex and softc variables.

- Refactor mailbox property API to make it usable for /dev/vcio driver.

- Replace semaphore-base locking with sleep/wait synchronization.

- Fix infinite loop if response from VideoCore never received.

- Set have_message in interrupt to handle "response before READ" case.

- Serialize access to property channel when using bcm2835_mbox_property.

- Force framebuffer virtual viewport to be the same as physical.

- Use proper type of tag in bcm2835_mbox_fb_init.

- bcm2835_cpufreq: Only attach driver if we correcly match on the machine
compatible string.

- Add dev.fb.X.resync sysctl to resync ARM framebuffer with VideoCore.

- Do not use DMA channels used by GPU.

- Define local-intc for BCM2836 platform (RPI2) and make BCM2835 intc
a child of it.

- Fix build for Pi kernels with syscons enabled.

- Use VM_MEMATTR_WRITE_COMBINING memattr for mmap(2) on framebuffer.

- Make intc driver compatible with upstream DTS.

- Make Rapsberry Pi watchdog driver compatible with upstream DTS.

- Make sure intc is attached before interrupt consumers.

- Make framebuffer driver compatible with upstream DT.

- Add one more heuristic to determine MAC address of the SMSC device.

- Add compatibility strings from upstream DT.

- Fix spelling mistake, BCM2835_PASWORD -> BCM2835_PASSWORD.

Resolve deadlock between device_detach() and usbd_do_request_flags()
by reviving the SX control request lock and refining which lock
protects the common scratch area in "struct usb_device".

The SX control request lock was removed by r246759 because it caused a
lock order reversal with the USB enumeration lock inside
usbd_transfer_setup() as a function of r246616. It was thought that
reducing the number of locks would resolve the LOR, but because some
USB device drivers use usbd_do_request_flags() inside callback
functions, like in taskqueues, a deadlock may occur when these are
drained from device_detach(). By restoring the SX control request
lock usbd_do_request_flags() is allowed to complete its execution
when a USB device driver is detaching. By using the SX control request
lock to protect the scratch area, the LOR introduced by r246616 is
also resolved.

Make PPS ASSERT/CLEAR events match the RS-232 signal levels as per RFC 2783.
Previously the polarity was for TTL levels, which are the reverse of RS-232.

Also add handling of the UART_PPS_INVERT_PULSE option bit in the sysctl
value, the same as was recently added to uart(4), so that people using TTL
level connections can request a logical inverting of the signal.

Use the named constants from the new dev/uart/uart_ppstypes.h for the pps
capture modes and option bits.

- Probe UICLASS_CDC/UISUBCLASS_ABSTRACT_CONTROL_MODEL/0xff again. This
variant of Microsoft RNDIS, i. e. their unofficial version of CDC ACM,
has been disabled in r261544 (r262363 in stable/10) for resolving a
conflict with umodem(4). Eventually, in r275790 (r276243 in stable/10)
that problem was dealt with in the right way. However, r275790 failed
to put probing of RNDIS devices in question back.
- Initialize the device prior to querying it, as required by the RNDIS
specification. Otherwise already determining the MAC address may fail
rightfully.
- On detach, halt the device again.
- Use UCDC_SEND_ENCAPSULATED_{COMMAND,RESPONSE}. While these macros are
resolving to the same values as UR_{CLEAR_FEATURE,GET_STATUS}, the
former set is way more appropriate in this context.
- Report unknown - rather: unimplemented - events unconditionally and
not just in debug mode. This ensures that we'll get some hint of what
is going wrong instead of the driver silently failing.
- Deal with the Microsoft ActiveSync requirement of using an input buffer
the size of the expected reply or larger - except for variably sized
replies - when querying a device.
- Fix some pointless NULL checks, style bugs etc.

This changes allow urndis(4) to communicate with a Microsoft-certified
USB RNDIS test token.

MFC r291953:
When setting up VLANs on a Raspberry Pi ethernet port, the MTU drops
from 1500 to 1496 bytes. The MTU should remain at 1500, extending the

if_capabilities field in the smsc driver solves the problem. The
datasheet for the LAN9512 chip, section 3.2.3 states that the chip

Workaround for for a problem seen with ATI Technologies EHCI
controller hardware most likely present on UHCI chipsets aswell. The
bug manifests itself when issuing isochronous transfers and bulk
transfers towards the same device simultaneously. From time to time it
happens that either the completion IRQ was missing or that the
completion IRQ was happening before the ITD/SITD was completely
written back to memory. The workaround assumes that double buffered
isochronous transfers are used, and that a second interrupt is
generated at the beginning of the next isochronous transfer to
complete the previous one. Possibly skipping the interrupt at the last
isochronous frame is possible, but will then break single buffered
isochronous transfers. For now we can live with some extra interrupts.

- Make quirk for reading device descriptor from broken USB devices.
Else they won't enumerate at all:
hw.usb.full_ddesc=1
- Reduce the USB descriptor read timeout from 1000ms to
500ms. Typical value for LOW speed devices is 50-100ms.
- Enumerate USB device a maximum of 3 times when a port
connection change event is detected, before giving up.
