The definitions are not used anywhere else, and merging it will
make adding the new USB definitions for XLPII series easier.
While there, cleanup some whitespace in usb-init.c. There is no
change to logic due to this commit.Signed-off-by: Jayachandran C

This enables us to have a default device tree per SoC family to be built
into the kernel. The default device tree for XLP3xx has been added as part
of this change. Later this can be used to provide support default boards
for XLP2xx and XLP9xx SoCs.Kconfig options are provided for each default device tree so that just the
needed ones can be selected to be built into the kernel.Signed-off-by: Jayachandran C

The index for a device interrupt in the PIC interrupt routing table

On multi-chip boards, the first core on slave SoCs may take much
more time to wakeup. Add code to wait for the core to come up before
proceeding with the rest of the boot up.Update xlp_wakeup_core to also skip the boot node and the boot CPU
initialization which is already complete.Signed-off-by: Jayachandran C

Doing calibrate delay on a hardware thread will be inaccurate since
it depends on the load on other threads in the core. It will also
slow down the boot process when done for 128 hardware threads. Switch
to a pre-computed loops per jiffy based on the core frequency. The
value is computed based on the core frequency and roughly matches the
value calculated by calibrate_delay().Signed-off-by: Jayachandran C

The XLR/XLS/XLP PIC has a 8 countdown timers which run at the PIC
frequencey. One of these can be used as a clocksource to provide
timestamps that is common across cores. This can be used in place
of the count/compare clocksource which is per-CPU.On XLR/XLS PIC registers are 32-bit, so we just use the lower 32-bits
of the PIC counter. On XLP, the whole 64-bit can be used.Provide common macros and functions for PIC timer registers on XLR/XLS
and XLP, and use them to register a PIC clocksource.Signed-off-by: Jayachandran C

Since we now use r4k cache code for Netlogic XLP, it is
better to split L1 icache among the active threads, so that
threads won't step on each other while flushing icache.The L1 dcache is already split among the threads in the core.

Provide functions ack_c0_eirr(), set_c0_eimr(), clear_c0_eimr()
and read_c0_eirr_and_eimr() that do the EIMR and EIRR operations
and update the interrupt handling code to use these functions.
Also, use the EIMR register functions to mask interrupts in the
irq code.The 64-bit interrupt request and mask registers (EIRR and EIMR) are
accessed when the interrupts are off, and the common operations are
to set or clear a bit in these registers. Using the 64-bit c0 access
functions for these operations is not optimal in 32-bit, because it
will disable/restore interrupts and split/join the 64-bit value during
each register access.Signed-off-by: Jayachandran C

Pull USB patches from Greg Kroah-Hartman:
"Here's the big set of USB patches for 3.8-rc1.Lots of USB host driver cleanups in here, and a bit of a reorg of the
EHCI driver to make it easier for the different EHCI platform drivers
to all work together nicer, which was a reduction in overall code. We
also deleted some unused firmware files, and got rid of the very old
file_storage usb gadget driver that had been broken for a long time.
This means we ended up removing way more code than added, always a
nice thing to see:
310 files changed, 3028 insertions(+), 10754 deletions(-)Other than that, the usual set of new device ids, driver fixes, gadget
driver and controller updates and the like.All of these have been in the linux-next tree for a number of weeks.

All architectures that use cmd_dtc do so in almost the same way. Create
a central build rule to avoid duplication. The one difference is that
most current uses of dtc build $(obj)/%.dtb from $(src)/dts/%.dts rather
than building the .dtb in the same directory as the .dts file. This
difference will be eliminated arch-by-arch in future patches.MIPS is the exception here; it already uses the exact same rule as the
new common rule, so the duplicate is removed in this patch to avoid any
conflict. arch/mips changes courtesy of Ralf Baechle.Update Documentation/kbuild to remove the explicit call to cmd_dtc from
the example, now that the rule exists in a centralized location.Cc: Arnd Bergmann

On XLR/XLS, the cpu cores communicate with fast on-chip devices
(e.g. network accelerator, security engine etc.) using the Fast
Messaging Network(FMN). The FMN queues and credits needs to be
configured and intialized before it can be used.The co-processor 2 on XLR/XLS CPU cores has registers for FMN access,
and the XLR/XLS has custom instructions for sending and loading
messages. The FMN can deliver also per-cpu interrupts when messages
are available at the CPU.This patch adds FMN initialization, adds interrupt setup and handling,
and also provides support for sending and receiving FMN messages.Signed-off-by: Ganesan Ramalingam
