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: @@ expression mc; expression isa_bus; @@ -smp_write_lintsrc(mc, mp_ExtINT, MP_IRQ_TRIGGER_DEFAULT|MP_IRQ_POLARITY_DEFAULT, isa_bus, 0x0, MP_APIC_ALL, 0x0); -smp_write_lintsrc(mc, mp_NMI, MP_IRQ_TRIGGER_DEFAULT|MP_IRQ_POLARITY_DEFAULT, isa_bus, 0x0, MP_APIC_ALL, 0x1); +mptable_lintsrc(mc, isa_bus); @@ expression mc; expression isa_bus; @@ -smp_write_lintsrc(mc, mp_ExtINT, MP_IRQ_TRIGGER_EDGE|MP_IRQ_POLARITY_HIGH, isa_bus, 0x0, MP_APIC_ALL, 0x0); -smp_write_lintsrc(mc, mp_NMI, MP_IRQ_TRIGGER_EDGE|MP_IRQ_POLARITY_HIGH, isa_bus, 0x0, MP_APIC_ALL, 0x1); +mptable_lintsrc(mc, isa_bus); @m@ identifier mc; expression BUS; @@ -#define IO_LOCAL_INT(type, intr, apicid, pin) smp_write_lintsrc(mc, (type), MP_IRQ_TRIGGER_EDGE | MP_IRQ_POLARITY_HIGH, BUS, (intr), (apicid), (pin)); ... -IO_LOCAL_INT(mp_ExtINT, 0x0, MP_APIC_ALL, 0x0); -IO_LOCAL_INT(mp_NMI, 0x0, MP_APIC_ALL, 0x1); +mptable_lintsrc(mc, BUS); Change-Id: I97421f820cd039f5fd753cb0da5c1cca68819bb4 Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Reviewed-on: http://review.coreboot.org/244 Tested-by: build bot (Jenkins) Reviewed-by: Marc Jones <marcj303@gmail.com>
