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>

This adds the URAM block on SH7722 as a separate node. Sparsemem is required for this, or it can simply be disabled by explicitly selecting a flatmem model. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This adds basic support for multiple nodes on SH machines. This is primarily useful for boards with many different memory blocks that are otherwise unused (SH7722/SH7785 URAM and so forth). Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This implements basic sparsemem support for SH. Presently this only uses static sparsemem, and we still permit explicit selection of flatmem. Those boards that want sparsemem can select it as usual. 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 was a big mess, rework the logic a bit so that we constrain to a particular subtype and figure out the board support based on that. This makes building subtype specific kernels supporting multiple boards possible again. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This converts the lazy dcache handling to the model described in Documentation/cachetlb.txt and drops the ptep_get_and_clear() hacks used for the aliasing dcaches on SH-4 and SH7705 in 32kB mode. As a bonus, this slightly cuts down on the cache flushing frequency. With that and the PTEA handling out of the way, the update_mmu_cache() implementations can be consolidated, and we no longer have to worry about which configuration the cache is in for the SH7705 case. And finally, explicitly disable the lazy writeback on SMP (SH-4A). Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The following moves the creation of IPR interupts into setup-7750.c and updates a few other things to make it all work after the "Drop CPU subtype IRQ headers" commit. It boots and runs fine on my titan board. - adds an ipr_idx to the ipr_data and uses a function in the subtype code to calculate the address of the IPR registers - adds a function to enable individual interrupt mode for externals in the subtype code and calls that from the titan board code instead of doing it directly. - I changed the shift in the ipr_data to be the actual # of bits to shift, instead of the numnber / 4 - made it easier to match with the manual.

This adds some preliminary support for the SH-X2 MMU, used by newer SH-4A parts (particularly SH7785). This MMU implements a 'compat' mode with SH-X MMUs and an 'extended' mode for SH-X2 extended features. Extended features include additional page sizes (8kB, 4MB, 64MB), as well as the addition of page execute permissions. The extended mode attributes are placed in a second data array, which requires us to switch to 64-bit PTEs when in X2 mode. With the addition of the exec perms, we also overhaul the mmap prots somewhat, now that it's possible to handle them more intelligently. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Currently the CPU subtype options are cluttering up arch/sh/Kconfig somewhat. Given that, this moves all of that in to its own arch/sh/mm/Kconfig. Things like cache configuration are also moved to this new location. This also adds support for strict CPU tuning on newer cores, which requires the addition of as-option.
