Stefan Reinauer 0aa37c488b sconfig: rename lapic_cluster -> cpu_cluster
The name lapic_cluster is a bit misleading, since the construct is not local
APIC specific by concept. As implementations and hardware change, be more
generic about our naming. This will allow us to support non-x86 systems without
adding new keywords.

The name pci_domain was a bit misleading, since the construct is only

by concept. As implementations and hardware change, be more generic
about our naming. This will allow us to support non-PCI systems without

Sven Schnelle 8c02790882 MPTABLE: check for fixed IRQ entries on all pins
Don't derive the IRQ pin from the function number. Especially onboard
chipset devices don't follow that rule. Instead check and add all
fixed IRQ entries.

Sven Schnelle 0fa50a1990 MPTAPLE: generate from devicetree.cb
This patch adds support for autogenerating the MPTABLE from
devicetree.cb. This is done by a write_smp_table() declared
weak in mpspec.c. If the mainboard doesn't provide it's own
function, this generic implementation is called.

Syntax in devicetree.cb:

ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN>

The ioapic_irq directive can be used in pci and pci_domain
devices. If there's no directive, the autogen code traverses
the tree back to the pci_domain and stops at the first device
which such a directive, and use that information to generate the
entry according to PCI IRQ routing rules.

Linux 2.6.11 seems to require a certain order in CPUs listed in mptable,
so enforce it. This was only done on arima/hdama, but now is generic.
Unfortunately this is somewhat slow.

Patrick Georgi 6eb7a53169 mptable: Refactor lintsrc generation
We copied pretty much the same code for generating mptable entries for
local interrupts (with some notable exceptions).
This change moves these lines into a generic function "mptable_lintsrc"
and makes use of it in many places.

The remaining uses of smp_write_lintsrc should be reviewed and replaced
by mptable_lintsrc calls where possible, and smp_write_lintsrc made static.

This patch was generated using Coccinelle:

Uwe Hermann c36d506a05 Get mptable OEM/product ID from kconfig variables.
We currently use "COREBOOT" unconditionally as the "OEM ID" in our
mptable.c files, and hardcode the mainboard name in mptable.c like this:

  mptable_init(mc, "DK8-HTX     ", LAPIC_ADDR);

However, the spec says

  "OEM ID: A string that identifies the manufacturer of the system hardware."
  (Table 4-2, page 42)

so "COREBOOT" doesn't match the spec, we should use the hardware vendor name.

Thus, use CONFIG_MAINBOARD_VENDOR which we have already as the "OEM ID"
(truncate/fill it to 8 characters as per spec).

Also, use CONFIG_MAINBOARD_PART_NUMBER (the board name) as "product ID",
and truncate/fill it to 12 characters as per spec, if needed.

Abuild-tested.
