c273652546 MIPS: Netlogic: Move cores per node out of multi-node.h 
Use the current_cpu_data package field to get the node of the current CPU.

This allows us to remove xlp_cores_per_node and move nlm_threads_per_node()
and nlm_cores_per_node() to netlogic/common.h, which simplifies code.

98d4884ca5 MIPS: Netlogic: Add cpu to node mapping for XLP9XX 
XLP9XX has 20 cores per node, opposed to 8 on earlier XLP8XX.
Update code that calculates node id from cpu id to handle this.

5513c760db MIPS: Netlogic: update iomap.h for XLP9XX 
Most IO block offsets have changed in XLP9XX. Update iomap.h to add the
new addresses of different SoC blocks like PIC, SYS, UART etc. that are
needed by the base code.

On XLP9xx, the SoC blocks of other nodes are seen on a PCI bus
corresponding to the node. Update iomap code to reflect this.

cfec4c63f5 MIPS: Netlogic: Add macro for node present 
Add macro nlm_node_present() that can be used to check if a node is present
in a multi-chip configuration. This can be used even when NUMA is not enabled.

bb1e4bc5cd MIPS: Netlogic: Make number of nodes configurable 
There can be 1, 2 or 4 SoCs(nodes) in a multi-chip XLP board. Add an
option for multi-chip boards in case of XLP, and make the number of
nodes configurable.
