Jayachandran C	5084e93dfe	MIPS: Netlogic: Handle XLP hardware errata ... Core configuration register IFU_BRUB_RESERVE has to be setup to handle a silicon errata which can result in a CPU hang.

Jayachandran C	a69ba6293d	MIPS: Netlogic: Split XLP L1 i-cache among threads ... Since we now use r4k cache code for Netlogic XLP, it is better to split L1 icache among the active threads, so that threads won't step on each other while flushing icache. The L1 dcache is already split among the threads in the core.

Jayachandran C	51d1eac0cd	MIPS: Netlogic: SMP wakeup code update ... Update for core intialization code. Initialize status register after receiving NMI for CPU wakeup. Add the low level L1D flush code before enabling threads in core. Also convert the ehb to _ehb so that it works under more GCC versions.
