soc/amd/picasso/acpi: Improve PCI Interrupt Link Devices
The PCI interrupt devices were only partially implemented. * Lacked support for _DIS to disable the bus. Something the kernel does while booting. * Lacked support for APIC vs PIC. This means the devices can only be used when using the PIC. By looking at the PMOD variable we can handle both PIC and APIC. This means we can stop hard coding the PCI interrupt numbers in the ACPI tables. * I removed INT[E-H] since they are not used. BUG=b:139429446, b:147042464 BRANCH=none TEST=Boot with both the APIC and PIC and saw that the link devices work as expected: PIC MODE: [ 1.959345] ACPI: PCI Interrupt Link [IRQA] (IRQs 1 3 4 5 *6 7 8 9 10 11 12 14 15) [ 2.007344] ACPI: PCI Interrupt Link [IRQB] (IRQs 1 3 4 5 *6 7 8 9 10 11 12 14 15) [ 2.056344] ACPI: PCI Interrupt Link [IRQC] (IRQs 1 3 4 5 6 7 8 9 10 11 12 *14 15) [ 2.104344] ACPI: PCI Interrupt Link [IRQD] (IRQs 1 3 4 5 6 7 8 9 10 11 12 14 *15) [ 13.752676] PCI Interrupt Link [IRQA] enabled at IRQ 6 [ 13.816755] PCI Interrupt Link [IRQD] enabled at IRQ 15 [ 27.788798] PCI Interrupt Link [IRQB] enabled at IRQ 6 [ 27.852873] PCI Interrupt Link [IRQC] enabled at IRQ 14 APIC MODE: [ 19.311764] ACPI: PCI Interrupt Link [IRQA] (IRQs *16 17 18 19 20 21 22 23) [ 19.374765] ACPI: PCI Interrupt Link [IRQB] (IRQs 16 *17 18 19 20 21 22 23) [ 19.438770] ACPI: PCI Interrupt Link [IRQC] (IRQs 16 17 *18 19 20 21 22 23) [ 19.501764] ACPI: PCI Interrupt Link [IRQD] (IRQs 16 17 18 *19 20 21 22 23) [ 34.719072] PCI Interrupt Link [IRQA] enabled at IRQ 23 [ 34.798994] PCI Interrupt Link [IRQD] enabled at IRQ 22 [ 66.469510] PCI Interrupt Link [IRQB] enabled at IRQ 21 [ 66.542395] PCI Interrupt Link [IRQC] enabled at IRQ 20 Change-Id: I1bb84813b65c89b4b5479602be3e9a9fedb7333d Reviewed-on: https://chromium-review.googlesource.com/c/chromiumos/third_party/coreboot/+/2095683 Signed-off-by: Raul E Rangel <rrangel@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/41438 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Felix Held <felix-coreboot@felixheld.de>
