* [MIPS] Fix KMODE for the R3000Maciej W. Rozycki2007-06-111-24/+28
| | | | | | | | | | | This must be the oldest bug that we have got. Leaving interrupts "as they are" for the R3000 obviously means copying IEp to IEc. Since we have got STATMASK now, I took this opportunity to mask the status register "correctly" for the R3000 now too. Oh, and the R3000 hardly ever is 64-bit. Signed-off-by: Maciej W.

* [MIPS] Add basic SMARTMIPS ASE supportFranck Bui-Huu2007-02-221-6/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds trivial support for SMARTMIPS extension. This extension is currently implemented by 4KS[CD] CPUs. Basically it saves/restores ACX register, which is part of the SMARTMIPS ASE, when needed. This patch does *not* add any support for Smartmips MMU features. Futhermore this patch does not add explicit support for 4KS[CD] CPUs since they are respectively mips32 and mips32r2 compliant. So with the current processor configuration, a platform that has such CPUs needs to select both configs: CPU_HAS_SMARTMIPS SYS_HAS_CPU_MIPS32_R[12] This is due to the processor configuration which is mixing up all the architecture variants and the processor types. The drawback of this, is that we currently pass '-march=mips32' option to gcc when building a kernel instead of '-march=4ksc' for 4KSC case. This can lead to a kernel image a little bit bigger than required. Signed-off-by: Franck Bui-Huu <fbuihuu@gmail.com> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
* [MIPS] Optimize and cleanup get_saved_sp, set_saved_spAtsushi Nemoto2006-10-111-45/+19
| | | | | | | | | | | | | | | If CONFIG_BUILD_ELF64 was not selected and gcc had -msym32 option (i.e. 4.0 or newer), there is no point to use %highest, %higher for kernel symbols. This patch also fixes 64-bit SMTC version of get_saved_sp() which is broken but harmless since there is no such CPUs for now. A bonus is set_saved_sp() and SMP version of get_saved_sp() are more readable now. Signed-off-by: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
