HI,

I use a custom kernel for ARM Cortex A9. When i enable the following
macros. it detects 2 cores

CONFIG_CACHE_L2X0=y
CONFIG_CACHE_PL310_INSN_PREFETCH=y
CONFIG_CACHE_PL310_DATA_PREFETCH=y
CONFIG_CACHE_PL310_PREFETCH_DOUBLE_LINEFILL=y
CONFIG_CACHE_PL310_PREFETCH_DROP=y
CONFIG_CACHE_PL310_STANDBY_MODE=y
CONFIG_CACHE_PL310_DYNAMIC_CLOCK_GATING=y

However, If i disable them it detects only One Core.

Any Idea why is this required?


Regards,
Ryan
