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.

We don't have a PMB for SH-X2 or later, so only enable it for the few CPUs that support it. Fixes up the boot for SH4AL-DSP. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

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. This patch reworks the intc2 code by moving the base addresses of the intc2 registers into struct intc2_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.

SH-2 can presently get in to some pretty bogus states, so we tidy up the dependencies a bit and get it all building again. This gets us a bit closer to a functional allyesconfig and allmodconfig, though there are still a few things to fix up. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This was added during 2.5.x, but was never moved along. This can easily be resurrected if someone has one they wish to work with, but it's not worth keeping around in its current form. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Currently cpu_to_node() is always 0 in the UP case, though we do want to have the CPU association linked in under sysfs even in the cases where we're only on a single CPU. Fix this up, so we have the cpu0 link on all of the available nodes that don't already have a CPU link of their own. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Now that select no longer works for selecting the "closest" CPU, we have to explicitly reference the precise sub-type in the few places where it actually matters (presently only setup code and some legacy sh-sci cruft). Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This kills off the BareCPU board as a "special" machvec, rather, we leave this as a default for when no other vector is available, or when we want to use it in combination with other vectors for testing with generic ops. As sh_mv is copied out anyways (or overloaded when an alternate vector is explicitly selected), this doesn't consume any additional memory. The generic machvec can be forcibly selected with sh_mv=generic, or by not having any other boards enabled. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

We now throw all of the machvecs in to .machvec.init and either select one on the command line, or copy out the first (and usually only) one to sh_mv. The rest are freed as usual. This gets rid of all of the silly sh_mv aliasing and makes the selection explicit rather than link-order dependent. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This tidies up the build rules and permits multiple boards to be linked in to the same kernel. The earlier Kconfig work ensures that the CPU configuration is consistent across the boards, as this is the only thing that we can't do dynamically. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>
