* sh: Re-add support for best fit ISA tuning if none is available.Paul Mundt2008-12-221-5/+20
| | | | | | | | | | | This was removed in the libgcc integration, but there are still some compilers that need this. We also relax the rules on the ISA tuning in the cases where there are no matches for the CPU tuning and adopt the -any default, which matches the intent of the isa-y target list. This compensates for mismatches where binutils supports a wide array of targets whilst the compiler is much more restricted. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: Provide optimized unaligned loads on SH-4A.Paul Mundt2008-12-222-1/+264
| | | | | | | | | | This adds support for unaligned loads on SH-4A, using the SH-4A's neutered movua.l instruction. As movua.l is r0-inspired, stores are still handled through the packed struct. Based on asm-generic/unaligned.h by Harvey Harrison. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: P4 ioremap pass-throughMagnus Damm2008-12-224-12/+17
| | | | | | | | | | | | | | | | | | | | This patch adds a pass-through case when ioremapping P4 addresses. Addresses passed to ioremap() should be physical addresses, so the best option is usually to convert the virtual address to a physical address before calling ioremap. This will give you a virtual address in P2 which matches the physical address and this works well for most internal hardware blocks on the SuperH architecture. However, some hardware blocks must be accessed through P4. Converting the P4 address to a physical and then back to a P2 does not work. One example of this is the sh7722 TMU block, it must be accessed through P4. Without this patch P4 addresses will be mapped using PTEs which requires the page allocator to be up and running.

(1) possible deadlock in microcode_resume_cpu() if either 'if' section is taken; (2) now, I don't see it in spec. and can't experimentally verify it (newer ucodes don't seem to be available for my Core2duo)... but logically-wise, I'd think that when read upon resuming, the 'microcode revision' (MSR 0x8B) should be back to its original one (we need to reload ucode anyway so it doesn't seem logical if a cpu doesn't drop the version)... if so, the comparison with memcmp() for the full 'struct cpu_signature' is wrong... and that's how one of the aforementioned 'if' sections might have been triggered - leading to a deadlock. Obviously, in my tests I simulated loading/resuming with the ucode of the same version (just to see that the file is loaded/re-loaded upon resuming) so this issue has never popped up. I'd appreciate if someone with an appropriate system might give a try to the 2nd patch (titled "fix a comparison && deadlock..."). In any case, the deadlock situation is a must-have fix.
