brcm2708: update against latest rpi-3.10.y branch 

Update our copies of the brcm2708 patches to the latest rpi-3.10-y
rebased against linux-3.10.y stable (3.10.32). This should hopefully
make it easier for us in the future to leverage the raspberry/rpi-*
branches.

Some additional quirks are needed for correct operation.
There's no SDHCI capabilities register documented, and it always reads
zero, so add SDHCI_QUIRK_MISSING_CAPS. Apparently
SDHCI_QUIRK_NO_HISPD_BIT is needed for many cards to work correctly in
high-speed mode, so add it as well.

Subject: [PATCH 017/174] sdhci-bcm2708: raise DMA sync timeout
Commit d64b84c by accident reduced the maximum overall DMA sync
timeout. The maximum overall timeout was reduced from 100ms to 30ms,
which isn't enough for many cards. Increase it to 150ms, just to be
extra safe. According to commit 872a8ff in the MMC subsystem, some
cards require crazy long timeouts (3s), but as we're busy-waiting,
and shouldn't delay for such a long time, let's hope 150ms will be
enough for most cards.

Subject: [PATCH 022/174] sdhci-bcm2708: use multiblock-type transfers for
single blocks
There are issues with both single block reads (missed completion)
and writes (data loss in some cases!). Just don't do single block
transfers anymore, and treat them like multiblock transfers. This
adds a quirk for this and uses it.

Subject: [PATCH 046/174] spi/spi-bcm2708: respect per-transfer SPI clock
speed_hz value
The bcm2708 SPI driver's bcm2708_process_transfer() was ignoring the
per-transfer speed_hz value even when it was provided (it always just
used the spi device's max_speed_hz value). Now, per-transfer speed_hz
values are respected.
Also added debug print to bcm2708_setup_state() to help keep an eye on
the configured SPI parameters.

Subject: [PATCH 049/174] dwc_otg: Fix unsafe access of QTD during URB enqueue
In dwc_otg_hcd_urb_enqueue during qtd creation, it was possible that the
transaction could complete almost immediately after the qtd was assigned
to a host channel during URB enqueue, which meant the qtd pointer was no
longer valid having been completed and removed. Usually, this resulted in
an OOPS during URB submission. By predetermining whether transactions
need to be queued or not, this unsafe pointer access is avoided.
This bug was only evident on the Pi model A where a device was attached
that had no periodic endpoints (e.g. USB pendrive or some wlan devices).

Subject: [PATCH 053/174] dwc_otg: fix potential use-after-free case in
interrupt handler
If a transaction had previously aborted, certain interrupts are
enabled to track error counts and reset where necessary. On IN
endpoints the host generates an ACK interrupt near-simultaneously
with completion of transfer. In the case where this transfer had
previously had an error, this results in a use-after-free on
the QTD memory space with a 1-byte length being overwritten to
0x00.

Subject: [PATCH 054/174] dwc_otg: add handling of SPLIT transaction data
toggle errors
Previously a data toggle error on packets from a USB1.1 device behind
a TT would result in the Pi locking up as the driver never handled
the associated interrupt. Patch adds basic retry mechanism and
interrupt acknowledgement to cater for either a chance toggle error or
for devices that have a broken initial toggle state (FT8U232/FT232BM).

Subject: [PATCH 057/174] dwc_otg: implement tasklet for returning URBs to
usbcore hcd layer
The dwc_otg driver interrupt handler for transfer completion will spend
a very long time with interrupts disabled when a URB is completed -
this is because usb_hcd_giveback_urb is called from within the handler
which for a USB device driver with complicated processing (e.g. webcam)
will take an exorbitant amount of time to complete. This results in
missed completion interrupts for other USB packets which lead to them
being dropped due to microframe overruns.
This patch splits returning the URB to the usb hcd layer into a
high-priority tasklet. This will have most benefit for isochronous IN
transfers but will also have incidental benefit where multiple periodic
devices are active at once.

Subject: [PATCH 060/174] dwc_otg: fix NAK holdoff and allow on split
transactions only
This corrects a bug where if a single active non-periodic endpoint
had at least one transaction in its qh, on frnum == MAX_FRNUM the qh
would get skipped and never get queued again. This would result in
a silent device until error detection (automatic or otherwise) would
either reset the device or flush and requeue the URBs.
Additionally the NAK holdoff was enabled for all transactions - this
would potentially stall a HS endpoint for 1ms if a previous error state
enabled this interrupt and the next response was a NAK. Fix so that
only split transactions get held off.

Subject: [PATCH 068/174] Speed up console framebuffer imageblit function
Especially on platforms with a slower CPU but a relatively high
framebuffer fill bandwidth, like current ARM devices, the existing
console monochrome imageblit function used to draw console text is
suboptimal for common pixel depths such as 16bpp and 32bpp. The existing
code is quite general and can deal with several pixel depths. By creating
special case functions for 16bpp and 32bpp, by far the most common pixel
formats used on modern systems, a significant speed-up is attained
which can be readily felt on ARM-based devices like the Raspberry Pi
and the Allwinner platform, but should help any platform using the
fb layer.
The special case functions allow constant folding, eliminating a number
of instructions including divide operations, and allow the use of an
unrolled loop, eliminating instructions with a variable shift size,
reducing source memory access instructions, and eliminating excessive
branching. These unrolled loops also allow much better code optimization
by the C compiler. The code that selects which optimized variant is used
is also simplified, eliminating integer divide instructions.
The speed-up, measured by timing 'cat file.txt' in the console, varies
between 40% and 70%, when testing on the Raspberry Pi and Allwinner
ARM-based platforms, depending on font size and the pixel depth, with
the greater benefit for 32bpp.

Subject: [PATCH 069/174] fbdev: add FBIOCOPYAREA ioctl
Based on the patch authored by Ali Gholami Rudi at
https://lkml.org/lkml/2009/7/13/153
Provide an ioctl for userspace applications, but only if this operation
is hardware accelerated (otherwide it does not make any sense).

Subject: [PATCH 070/174] bcm2708_fb: DMA acceleration for fb_copyarea
Based on http://www.raspberrypi.org/phpBB3/viewtopic.php?p=62425#p62425
Also used Simon's dmaer_master module as a reference for tweaking DMA
settings for better performance.
For now busylooping only. IRQ support might be added later.
With non-overclocked Raspberry Pi, the performance is ~360 MB/s
for simple copy or ~260 MB/s for two-pass copy (used when dragging
windows to the right).
In the case of using DMA channel 0, the performance improves
to ~440 MB/s.
For comparison, VFP optimized CPU copy can only do ~114 MB/s in
the same conditions (hindered by reading uncached source buffer).

Subject: [PATCH 071/174] dwc_otg: Call usb_hcd_unlink_urb_from_ep with lock
held in completion handler
usb_hcd_unlink_urb_from_ep must be called with the HCD lock held. Calling it
asynchronously in the tasklet was not safe (regression in
c4564d4a1a0a9b10d4419e48239f5d99e88d2667).
This change unlinks it from the endpoint prior to queueing it for handling in
the tasklet, and also adds a check to ensure the urb is OK to be unlinked
before doing so.
NULL pointer dereference kernel oopses had been observed in usb_hcd_giveback_urb
when a USB device was unplugged/replugged during data transfer. This effect
was reproduced using automated USB port power control, hundreds of replug
events were performed during active transfers to confirm that the problem was
eliminated.

Subject: [PATCH 078/174] dwc_otg: mask correct interrupts after transaction
error recovery
The dwc_otg driver will unmask certain interrupts on a transaction
that previously halted in the error state in order to reset the
QTD error count. The various fine-grained interrupt handlers do not
consider that other interrupts besides themselves were unmasked.
By disabling the two other interrupts only ever enabled in DMA mode
for this purpose, we can avoid unnecessary function calls in the
IRQ handler. This will also prevent an unneccesary FIQ interrupt
from being generated if the FIQ is enabled.

Subject: [PATCH 079/174] dwc_otg: fiq: prevent FIQ thrash and incorrect state
passing to IRQ
In the case of a transaction to a device that had previously aborted
due to an error, several interrupts are enabled to reset the error
count when a device responds. This has the side-effect of making the
FIQ thrash because the hardware will generate multiple instances of
a NAK on an IN bulk/interrupt endpoint and multiple instances of ACK
on an OUT bulk/interrupt endpoint. Make the FIQ mask and clear the
associated interrupts.
Additionally, on non-split transactions make sure that only unmasked
interrupts are cleared. This caused a hard-to-trigger but serious
race condition when you had the combination of an endpoint awaiting
error recovery and a transaction completed on an endpoint - due to
the sequencing and timing of interrupts generated by the dwc_otg core,
it was possible to confuse the IRQ handler.

Subject: [PATCH 082/174] dwc_otg: prevent OOPSes during device disconnects
The dwc_otg_urb_enqueue function is thread-unsafe. In particular the
access of urb->hcpriv, usb_hcd_link_urb_to_ep, dwc_otg_urb->qtd and
friends does not occur within a critical section and so if a device
was unplugged during activity there was a high chance that the
usbcore hub_thread would try to disable the endpoint with partially-
formed entries in the URB queue. This would result in BUG() or null
pointer dereferences.
Fix so that access of urb->hcpriv, enqueuing to the hardware and
adding to usbcore endpoint URB lists is contained within a single
critical section.

Subject: [PATCH 083/174] dwc_otg: prevent BUG() in TT allocation if hub
address is > 16
A fixed-size array is used to track TT allocation. This was
previously set to 16 which caused a crash because
dwc_otg_hcd_allocate_port would read past the end of the array.
This was hit if a hub was plugged in which enumerated as addr > 16,
due to previous device resets or unplugs.
Also add #ifdef FIQ_DEBUG around hcd->hub_port_alloc[], which grows
to a large size if 128 hub addresses are supported. This field is
for debug only for tracking which frame an allocate happened in.

Subject: [PATCH 084/174] dwc_otg: make channel halts with unknown state less
damaging
If the IRQ received a channel halt interrupt through the FIQ
with no other bits set, the IRQ would not release the host
channel and never complete the URB.
Add catchall handling to treat as a transaction error and retry.

Subject: [PATCH 085/174] dwc_otg: fiq_split: use TTs with more granularity
This fixes certain issues with split transaction scheduling.
- Isochronous multi-packet OUT transactions now hog the TT until
they are completed - this prevents hubs aborting transactions
if they get a periodic start-split out-of-order
- Don't perform TT allocation on non-periodic endpoints - this
allows simultaneous use of the TT's bulk/control and periodic
transaction buffers
This commit will mainly affect USB audio playback.

Subject: [PATCH 088/174] dwc_otg: prevent crashes on host port disconnects
Fix several issues resulting in crashes or inconsistent state
if a Model A root port was disconnected.
- Clean up queue heads properly in kill_urbs_in_qh_list by
removing the empty QHs from the schedule lists
- Set the halt status properly to prevent IRQ handlers from
using freed memory
- Add fiq_split related cleanup for saved registers
- Make microframe scheduling reclaim host channels if
active during a disconnect
- Abort URBs with -ESHUTDOWN status response, informing
device drivers so they respond in a more correct fashion
and don't try to resubmit URBs
- Prevent IRQ handlers from attempting to handle channel
interrupts if the associated URB was dequeued (and the
driver state was cleared)

Subject: [PATCH 091/174] ARM: 7819/1: fiq: Cast the first argument of
flush_icache_range()
Commit 2ba85e7af4 (ARM: Fix FIQ code on VIVT CPUs) causes the following build warning:
arch/arm/kernel/fiq.c:92:3: warning: passing argument 1 of 'cpu_cache.coherent_kern_range' makes integer from pointer without a cast [enabled by default]
Cast it as '(unsigned long)base' to avoid the warning.

Subject: [PATCH 093/174] dwc_otg: Enable NAK holdoff for control split
transactions
Certain low-speed devices take a very long time to complete a
data or status stage of a control transaction, producing NAK
responses until they complete internal processing - the USB2.0
spec limit is up to 500mS. This causes the same type of interrupt
storm as seen with USB-serial dongles prior to c8edb238.
In certain circumstances, usually while booting, this interrupt
storm could cause SD card timeouts.
