2020-04-10Replace DEVICE_NOOP with noop_(set|read)_resourcesNico Huber
`.read_resources` and `.set_resources` are the only two device operations that are considered mandatory. Other function pointers can be left NULL. Having dedicated no-op implementations for the two mandatory fields should stop the leaking of no-op pointers to other fields.

2020-04-10Drop unnecessary DEVICE_NOOP entriesNico Huber
Providing an explicit no-op function pointer is only necessary for `.read_resources` and `.set_resources`. All other device-operation pointers are optional and can be NULL.

2020-04-05Drop explicit NULL initializations from `device_operations`Elyes HAOUAS
Unmentioned fields are initialized with 0 (or NULL) implicitly. Beside that, the struct has grown over the years. There are too many optional fields to list them all.

2020-04-04soc/intel/xeon_sp/cpx: Add multi-core initAndrey Petrov
Add minimal MP init. No SMM, no turbo, not c/p states. TEST=boot linux kernel, observe CPUs are online, schedule tasks and perform useful work. Tested on Cedar Island CRB with only 1 socket populated Change-Id: I0af374ab3956009e9208917d911d29eb21db6069 Signed-off-by: Andrey Petrov <anpetrov@fb.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40035 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Maxim Polyakov <max.senia.poliak@gmail.com>
2020-03-26soc/intel/xeon_sp: Add basic Cooperlake-SP supportAndrey Petrov
This adds barebones support. What works: * Linux kernel boots fine * SIRQ and PCH interupts work fine (only in IOAPIC mode) * PCH devices are usable What doesn't: * MP init is not there yet, only 1 CPU is up * SMM is not supported * GPIO is not available * All IIO and extended bus numbers enumeration is not yet available * Warm reset flow is untested * MRC cache save/load TEST=boots into Linux Signed-off-by: Andrey Petrov <anpetrov@fb.com> Change-Id: I7c987badc3c53f16ad178369c7e0906d6596e465 Reviewed-on: https://review.coreboot.org/c/coreboot/+/39713 Reviewed-by: Maxim Polyakov <max.senia.poliak@gmail.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
