[LinuxBIOS] node id and core id in internal tree

[Lu, Yinghai]

Eric,

It seems that cpu_path and cpu_bus_path in include/device/path.h are not
used.

So what do you prefer

struct apic_path

{

unsigned apic_id;

unsigned node id;

unsigned core_id;

}

Or

struct cpu_path

{

unsigned id;

unsigned apic_id;

unsigned node_id;

unsigned core_id;

}

YH

Stepan: No, the information has to be reorganized. Currently pirq and
mptables
Stepan: have to be hand crafted, and this is the complicated thing.
Instead the
Stepan: abstract information should be put to the configuration filess,
if it
Stepan: can not be probed.

YH: I suggest to add
1. one node id to ram_resource, so the index will be (idx<<8 | nodeid),
So I can re-use ram_resource in pci_domain for SRAT creating.
2. for apci_cluster_id, will add two fields core_id and node_id, (
instantiate it when cpu_init)...
3. pci device: add pci_irq_routing, and pci_possiable_resource ( for
apci _PRT and _PRS...)

how about ioapci in the internal tree?
