ARM: implement debug_ll_io_init()
When using DEBUG_LL, the UART's (or other HW's) registers are mapped
into early page tables based on the results of assembly macro addruart.
Later, when the page tables are replaced, the same virtual address must
remain valid. Historically, this has been ensured by using defines from
<mach/iomap.h> in both the implementation of addruart, and the machine's
.map_io() function. However, with the move to single zImage, we wish to
remove <mach/iomap.h>. To enable this, the macro addruart may be used
when constructing the late page tables too; addruart is exposed as a
C function debug_ll_addr(), and used to set up the required mapping in
debug_ll_io_init(), which may called on an opt-in basis from a machine's
.map_io() function.

ARM: vexpress: Start using new Versatile Express infrastructure
This patch starts using all the configuration infrastructure.
- generic GPIO library is forced now
- sysreg GPIOs are used as MMC CD and WP information sources;
thanks to this MMCI auxiliary data is not longer necessary
- DVI muxer and mode control is removed from non-DT V2P-CA9 code
as this is now handled by the vexpress-dvi driver
- clock generators control is removed as is being handled by the
common clock driver now
- the sysreg and sysctl control is now delegated to the
appropriate drivers and all related code was removed
- NOR Flash set_vpp function has been removed as the control
bit used does _not_ control its VPP line, but the #WP signal
instead (which is de facto unusable in case of Linux MTD
drivers); this also allowed the remove its DT auxiliary
data
The non-DT code defines only minimal required number of
the config devices. Device Trees are updated to make use
of all new features.
ARM: vexpress: Add config bus components and clocks to DTs
Add description of all functions provided by Versatile Express
motherboard and daughterboards configuration controllers and
clock dependencies between devices.
This is a platform driver for Versatile Express' "system
register" block. It's a random collection of registers providing
the following functionality:
- low level platform functions like board ID access; in order to
use those, the driver must be initialized early, either statically
or based on the DT
- config bus bridge via "system control" interface; as the response
from the controller does not generate interrupt (yet), the status
register is periodically polled using a timer
- pseudo GPIO lines providing MMC card status and Flash WP#
signal control
- LED interface for a set of 8 LEDs on the motherboard, with
"heartbeat", "mmc0" and "cpu0" to "cpu5" as default triggers
Versatile Express platform has an elaborated configuration system,
consisting of microcontrollers residing on the mother- and
daughterboards known as Motherboard/Daughterboard Configuration
Controller (MCC and DCC). The controllers are responsible for
the platform initialization (reset generation, flash programming,
FPGA bitfiles loading etc.) but also control clock generators,
voltage regulators, gather environmental data like temperature,
power consumption etc. Even the video output switch (FPGA) is
controlled that way.
Those devices are _not_ visible in the main address space and
the usual communication channel uses some kind of a bridge in
the peripheral block sending commands (requests) to the
controllers and receiving responses. It can take up to
500 microseconds for a transaction to be completed, therefore
it is important to provide a non-blocking interface to it.
This patch adds an abstraction of this infrastructure. Bridge
drivers can register themselves with the framework. Then,
a driver of a device can request an abstract "function" - the
request will be redirected to a bridge referred by thedd
"arm,vexpress,config-bridge" property of the device tree node.

When creating an L2TPv3 Ethernet session, if register_netdev() should fail for

Subject: frv: split ret_from_fork, simplify kernel_thread() a lot
The problem is that the userspace registers are completely cleared when a
kernel thread is created and all subsequent user threads are then copied from
that. Unfortunately, however, the TBR and PSR registers are restored from the
pt_regs and the values they should be set to are clobbered by the memset.
Instead, copy across the old user registers as normal, and then merely alter
GR8 and GR9 in it if we're going to execute a kernel thread.

Fix the preemption handling in FRV code where the PREEMPT_ACTIVE value is
incorrectly loaded into the threadinfo flags rather than the threadinfo

Unfortunately, the code cannot be simply converted to use
preempt_schedule_irq() as is because FRV uses virtual interrupt disablement to
cut down on the cost of actually disabling interrupts and thus
local_irq_enable() doesn't actually enable interrupts.

i2c: mxs: remove broken PIOQUEUE support
This I2C master can do DMA and PIOQUEUE (PIO with FIFO). Originally,
only PIOQUEUE was supported and it had issues, then DMA support was added
this cycle. The original intention was to keep PIOQUEUE since it has
less overhead what is nice for small transfers. However, runtime
switching between PIOQEUE and DMA depending on the transfer size never
worked despite a lot of trying. Since PIOQUEUE mode itself was flaky
(polling at places where interrupts failed to work) and the
implementation also imposed a size limit for transfers, it is best to
remove the support, so users don't fall over its limitations. It also
makes the driver a lot cleaner and more robust. If somebody really wants
less overhead, plain PIO mode could still be implemented with the
addidtional advantage that this mode is also available on MX23, too.
