There was a very preliminary bunch of SMP code scattered around for the
SH7604 microcontrollers from way back when, and it has mostly suffered
bitrot since then. With the tree already having been slowly getting
prepped for SMP, this plugs in most of the remaining platform-independent
bits.

This implements initial support for the SMP INTC (particularly
INTC2) controllers.

These are largely implemented as conventional blocks, with
register sets grouped together at fixed strides relative to

This consolidates the cpu_data definitions and gets rid of the special

The Maple bus is SEGA's proprietary serial bus for peripherals
(keyboard, mouse, controller etc). The bus is capable of some
(limited) hotplugging and operates at up to 2 M/bits.

Drivers of one sort or another existed/exist for 2.4 and a rudimentary
port, which didn't support the 2.6 device driver model was also in
existence.

This driver - for the bus logic itself and for the keyboard (other
drivers will follow) are based on the code and concepts of those old
drivers but have lots of completely rewritten parts.

I have the maple bus code as a built in now as that seems the sane and
rational way to handle something like that - you either want the bus
or you don't.

The extended mode TLB requires both 64-bit PTEs and a 64-bit pgprot,
correspondingly, the PGD also has to be 64-bits, so fix that up.

The kernel and user permission bits really are decoupled in early
cuts of the silicon, which means that we also have to set corresponding
kernel permissions on user pages or we end up with user pages that the
kernel simply can't touch (!).

Finally, with those things corrected, really enable MMUCR.ME and
correct the PTEA value (this simply needs to be the upper 32-bits
of the PTE, with the size and protection bit encoding).

This patch reworks the highlander irq code for r7780mp and r7785rp.
The same strategy as for the new R2D code is used here - the board
specific interrupts are now starting from HL_FPGA_IRQ_BASE. The code
for r7780rp is not touched due to lack of hardware.

Tested with CF, AX88796 on r7780mp and r7785rp. The touch switch
interrupt has also been tested on r7780mp.
