Thomas Bogendoerfer	7a2852e49f	[MIPS] IP28: switch to "normal" mode after PROM no longer needed ... 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.

Ralf Baechle	17099b1142	[MIPS] Make support for weakly ordered LL/SC a config option. ... 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>	2007-07-20 18:57:39 +01:00
Ralf Baechle	0004a9dfea	[MIPS] Cleanup memory barriers for weakly ordered systems. ... Also the R4000 / R4600 LL/SC instructions imply a sync so no explicit sync needed. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>	2006-12-04 22:43:14 +00:00
