325c117000 mn10300: move setup_jiffies_interrupt() to cevt-mn10300.c
Move the static inline function setup_jiffies_interrupt() from
<asm/timex.h> to arch/mn10300/kernel/cevt-mn10300.c, which is its only
callsite.

This allows to remove the inclusion of <asm/hardirq.h> and <linux/irq.h>
from <asm/timex.h> and <unit/timex.h>, fixing include hell like:

  include/linux/jiffies.h:260:31: warning: "CLOCK_TICK_RATE" is not defined [-Wundef]
  include/linux/jiffies.h:260:31: warning: "CLOCK_TICK_RATE" is not defined [-Wundef]
  include/linux/jiffies.h:46:42: error: division by zero in #if
  ...
  make[4]: *** [arch/mn10300/kernel/asm-offsets.s] Error 1

and (after a quick hack for the above by defining CLOCK_TICK_RATE in
<linux/jiffies.h>):

  In file included from include/linux/notifier.h:15:0,
                 from include/linux/memory_hotplug.h:6,
                 from include/linux/mmzone.h:718,
                 from include/linux/gfp.h:4,
                 from include/linux/irq.h:20,
                 from arch/mn10300/unit-asb2303/include/unit/timex.h:15,
                 from arch/mn10300/include/asm/timex.h:15,
                 from include/linux/timex.h:174,
                 from include/linux/jiffies.h:8,
                 from include/linux/ktime.h:25,
                 from include/linux/timer.h:5,
                 from include/linux/workqueue.h:8,
  include/linux/srcu.h:55:22: error: field 'work' has incomplete type

As a consequence, we do need a few more inclusions of <asm/irq.h>, namely
in arch/mn10300/unit-asb2303/smc91111.c and
arch/mn10300/unit-asb2305/unit-init.c.

2f2a2132ff Separate out the proc- and unit-specific header directories from the general
MN10300 arch headers and place them instead in the same directories as contain
the .c files for the processor and unit implementations.

This permits the symlinks include/asm/proc and include/asm/unit to be
dispensed with.  This does, however, require that #include <asm/proc/xxx.h> be
converted to #include <proc/xxx.h> and similarly for asm/unit -> unit.

b920de1b77 mn10300: add the MN10300/AM33 architecture to the kernel
Add architecture support for the MN10300/AM33 CPUs produced by MEI to the
kernel.

This patch also adds board support for the ASB2303 with the ASB2308 daughter
board, and the ASB2305.  The only processor supported is the MN103E010, which
is an AM33v2 core plus on-chip devices.
