Kumar Gala 43f082bb7f powerpc/85xx: Add workaround for erratum CPU-A003999 ... Erratum A-003999: Running Floating Point instructions requires special initialization. Impact: Floating point arithmetic operations may result in an incorrect value. Workaround: Perform a read modify write to set bit 7 to a 1 in SPR 977 before executing any floating point arithmetic operation. This bit can be set when setting MSR[FP], and can be cleared when clearing MSR[FP]. Alternatively, the bit can be set once at boot time, and never cleared. There will be no performance degradation due to setting this bit. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>		2011-11-29 08:48:05 -06:00
