The JZ4740 UART interface is almost 16550 compatible.
The UART module needs to be enabled by setting a bit in the FCR register
and it has support for receive timeout interrupts. Instead of adding yet
another machine specific quirk to the 8250 serial driver we provide a
serial_out implementation which sets the required additional flags.

The use of handle_percpu_irq() is not really what we want for MSI, use
handle_simple_irq() instead. This is probably the prototypical case
for using handle_simple_irq(), because all the MSIs are dispatched from
the root interrupt service routine.
Also since the base IRQ is not shared, don't pass IRQF_SHARED.

The main change is to change most of the IRQs from handle_percpu_irq
to handle_fasteoi_irq. This necessitates extracting all the .ack code
to common functions that are not exposed to the irq core.
The affinity code now acts more sanely, by doing round-robin
distribution instead of broadcasting.
Because of the change to handle_fasteoi_irq and affinity, some of the
IRQs had to be split into separate groups with their own struct
irq_chip to prevent undefined operations on specific IRQ lines.

In recent years, however, we've brought it back to normal order, and now
CPU_IRQ_BASE just redefines the generic MIPS_CPU_IRQ_BASE.
At the same time, NUM_CPU_IRQ is also removed as useless.

Additional changes to Youichi Yuasa's command line simplication code
The PowerTV platform uses a non-standard way to get the kernel command
line--we insert a built-in command line into arcs_cmdline and to
get additional command line information from the bootloader via a
pointer in the a1 register. It is necessary to insert a space between
to the two strings or the last argument from arcs_cmdline and the first
argument from the bootloader may be inadvertantly combined.
It is also necessary to set CONFIG_CMDLINE_BOOL to "y" and to set the
default command line to an empty string to get the simplified code to
work properly in the PowerTV environment.

Adding the definition to Kbuild as a recursive

With this change we now compile arch/mips/kernel/cpufreq with -Werror
One drawback:
When specifying a subdirectory covered by the Kbuild file like this:
make arch/mips/kernel/
then kbuild fails to pick up the -Werror definition.

Replace phys_to_dma()/dma_to_phys() looping algorithm with an O(1) algorithm
The approach taken is inspired by the sparse memory implementation: take a
certain number of high-order bits off the address them, use this as an
index into a table containing an offset to the desired address and add
it to the original value. There is a table for mapping physical addresses
to DMA addresses and another one for the reverse mapping. The table sizes
depend on how fine-grained the mappings need to be; Coarser granularity
less to smaller tables. On a processor with 32-bit physical and DMA
addresses, with 4 MIB granularity, memory usage is two 2048-byte arrays.
Each 32-byte cache line thus covers 64 MiB of address space.
Also, renames phys_to_bus() to phys_to_dma() and bus_to_phys() to
dma_to_phys() to align with kernel usage.

The BCM47xx architecture maps the ram into a 128MB address space. It

find the position where the same memory is found. When reading beyond
128MB the processor will throw an exception. If 128MB RAM is installed,
it will not find a memory alias because it tries to read beyond the 128MB
border. Now it just assumes 128MB installed ram if it can not find an

xen_sched_clock only counts unstolen time. In principle this should
be useful to the Linux scheduler so that it knows how much time a process
actually consumed. But in practice this doesn't work very well as the
scheduler expects the sched_clock time to be synchronized between
cpus. It also uses sched_clock to measure the time a task spends
sleeping, in which case "unstolen time" isn't meaningful.
So just use plain xen_clocksource_read to return wallclock nanoseconds
for sched_clock.

Introduce basic support for the Freescale P1022DS reference board, based on the
Freescale BSP for this board. This patch excludes the DIU, SSI, and MMC/SD
drivers. Only a 36-bit DTS is provided.
Update mpc86xx_smp_defconfig and mpc85xx_defconfig to support the P1022DS.
This means enabling 64-bit physical address support, increasing the maximum
zone order to 12 (to allow the DIU driver to allocate large chunks), and
clean up the audio options to disable the deprecated OSS support.

This version uses "fsl,mpc8555..." instead of "fsl,85..." notation.
There is also an 8541 version of this board so DTS for this board
is specific to the 8555 processor.
Another patch is coming to fix-up other DTS that use old notation.

The mpc85xx_mds_setup_arch() function is incomprehensible
and unmaintainable. Factor out all QE specific stuff into
mpc85xx_mds_qe_init() and mpc85xx_mds_reset_ucc_phys().
Also move QE stuff out of mpc85xx_mds_pic_init().
The diff is unreadable, but only because the code was so. ;-)
It should be better now, and less indented.

P1021 processors have no dedicated ROM to store the QE microcode,
so the fimrware is stored externally, and it is U-Boot responsibility
to load it. It might be that the board is booting without QE, e.g.
currently U-Boot doesn't support QE for P1021MDS boards, which means
that QE isn't initialized, and so the board hangs early at boot.
This patch fixes the issue by marking QE as disabled and checking the
state in the probing code. U-Boot should fixup the state if it
initialized the QE.

The code inside '#ifdef CONFIG_QUICC_ENGINE' makes the
mpc85xx_mds_setup_arch() return early if no QE nodes present,
and so SWIOTLB is never initialized.
This patch fixes the issue by moving SWIOTLB code above
QE.

Manually fix up conflicts in:

infrastructure changes
- drivers/net/phy/marvell.c: conflict between adding 88ec048 support
and cleaning up the IDs
- drivers/net/wireless/ipw2x00/ipw2100.c: trivial ipw2100_pm_qos_req
conflict (registration change vs marking it static)
The firmware handles '\t' internally, so stop trying to emulate it
(which, incidentally, had a bug in it.)
Fixes a really weird hang at bootup in rcu_bootup_announce, which,
as far as I can tell, is the first printk in the core kernel to use
a tab as the first character.
