This patch adds NOR flash support to the kfr2r09 board.

NOR flash support is added by describing the NOR flash
chip hooked up to CS0 as platform device data for the
physmap-flash MTD driver.

This patch adds basic kfr2r09 board support. Only
the SCIF1 console is supported with this patch, but
this patch and a proper sh7724 configuration is all
that is needed. Combine with an initramfs to have a
small RAM based kernel and distribution booted as
zImage from RAM via JTAG.

* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
  It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

  This will make hardirq.h inclusion cheaper for every PREEMPT=n config
  (which includes allmodconfig/allyesconfig, BTW)

Pull the initial preempt_count value into a single
definition site.

Maintainers for: alpha, ia64 and m68k, please have a look,
your arch code is funny.

The header magic is a bit odd, but similar to the KERNEL_DS
one, CPP waits with expanding these macros until the
INIT_THREAD_INFO macro itself is expanded, which is in
arch/*/kernel/init_task.c where we've already included
sched.h so we're good.

Add USB host support for port CN27 on the Solution Engine 7724
board. The r8a66597-hcd driver is hooked up as a platform device
and some registers are configured to enable the USB host function.
The hardware driving the USB port is the on-chip USB0 block in
the sh7724 processor configured as USB host controller.

SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2

set_pte_phys() presently uses the global flush_tlb_one(), which locks on

at this point, switch to the local_ variant so the flush happens on the

This allows the callers to now pass down the full set of FAULT_FLAG_xyz
flags to handle_mm_fault().  All callers have been (mechanically)

for architectures to clean up their code and then add FAULT_FLAG_RETRY
when that support is added.

This adds initial support for the PCI-Express module in the SH7786,
particularly as it relates to the urquell platform. Presently it is
only supported in root complex mode, with endpoint mode still requiring
more debugging. 29/32-bit mode and lane configurations are selectable via
board mode pins, and are otherwise fixed.

Only 4x and 1x PCI channels are presently handled, the PCI bridge still
requires additional debugging and stabilization in hardware.
