2008-07-15[MIPS] IP28: switch to "normal" mode after PROM no longer neededThomas Bogendoerfer
SGI-IP28 is running in so called slow mode, when kernel is started from the PROM. PROM calls must be done in slow mode otherwise the PROM will issue an error. To get better memory performance we now switch to normal mode, when the PROM is no longer needed.

2007-07-20[MIPS] Make support for weakly ordered LL/SC a config option.Ralf Baechle
None of weakly ordered processor supported in tree need this but it seems like this could change ... Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
2006-12-04[MIPS] Cleanup memory barriers for weakly ordered systems.Ralf Baechle
Also the R4000 / R4600 LL/SC instructions imply a sync so no explicit sync needed. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
