This header is needed on other architectures as well (namely h8300),
which currently fails to build without this in place. Rather than
duplicating the port definition completely there, just move this to a
common location instead.
This should get h8300 working again for 2.6.25, in addition to the
changes already pushed by Sato-san in -rc2.

This patch removes interrupt priority tables from the intc code.
Optimal priority assignment varies with embedded application anyway,
so keeping the interrupt priority tables together with cpu-specific
code doesn't make sense.
The function intc_set_priority() should be used instead to set the
desired interrupt priority level.

With the intc core improved it is now possible to put the intc data
structures in the initdata section.
Version two of this patch puts the __initdata inside DECLARE_INTC_DESC()
and removes the __initdata included in the board specific r2d code.

We need a secondary register member in struct intc_prio_reg to support
dual priority registers used by ipi on x3.

This patch converts the cpu specific interrupt setup code for sh7760
from ipr + intc2 to intc. New vectors are also added to match the
information provided by the datasheet.
Vectors for IRQ4-IRQ7 are enabled by default. Use plat_irq_setup_pins()
if pins IRL0-3 should be used in IRLM mode.
The patch also adds the SIM block to the serial port platform data.
Version two of this patch fixes MMCIF problems reported by Manuel Lauss.

This patch unifies the cpu specific interrupt setup functions for
interrupt controller blocks such as ipr, intc2 and intc. There is no
point in having separate functions for each interrupt controller, so
let's clean this up.

This patch reworks the ipr code by grouping the offset array together
with the ipr_data structure in a new data structure called ipr_desc.
This new structure also contains the name of the controller in struct
irq_chip. The idea behind putting struct irq_chip in there is that we
can use offsetof() to locate the base addresses in the irq_chip
callbacks. This strategy has much in common with the recently merged
intc2 code.
One logic change has been made - the original ipr code enabled the
interrupts by default but with this patch they are all disabled by
default.

The shared intc2 code currently contains cpu-specific #ifdefs.
This is a tad unclean and it prevents us from using the shared code
to drive board-specific irqs on the se7780 board.

the intc2 registers into struct intc2_desc. This new structure also
contains the name of the controller in struct irq_chip. The idea

Currently the INTC2 code contains a fixed IRQ table that it
iterates through to set the handler type, we move this in to
the CPU subtype setup code instead and allow for submitting
the table that way.
This drops the ST40 tables, as nothing has been happening
with those processors, while converting the only existing
users to use the new table directly (SH7760 and SH7780).

This adds some simple setup code for most of the CPU subtypes,
primarily simple platform device registration.
