2024-06-08soc/alderlake/romstage: Set UsbTcPortEnPreMem UPD based on devicetreeMichał Żygowski
The UsbTcPortEn UPD for FSP-S is being set in ramstage, however the equivalent FSP-M UPD, the UsbTcPortEnPreMem, was not being set. Following the Meteor Lake example, set the UsbTcPortEnPreMem UPD as well for Alder Lake. Setting this FSP-M UPD will cause FSP to properly program sideband use BSSB_LSx pins for the enabled Type-C ports. Required for proper DCI debug and TCSS initialization flow.

2024-06-07soc/intel/common/uart: Drop chip in favor of devicetree opsArthur Heymans
It is now possible to hook up device ops directly to devices in devicetree which removes the need for a fake chip. This also fixes Hermes booting as the PCI ops were incorrectly hooked up to a dummy device. The intel uart driver was requesting a resource from the generic device and died since it does not exist: [EMERG] GENERIC: 0.0 missing resource: 10 This was broken in commit b9165199c32a (mb/prodrive/hermes: Rework UART devicetree entry).

2024-06-05cpu/x86: Make 1GB paging the defaultJulius Werner
This patch flips the polarity of CONFIG_USE_1G_PAGES_TLB into CONFIG_NEED_SMALL_2MB_PAGE_TABLES which is off by default, meaning CPUs added in the future will automatically build the smaller 1GB pages. We can expect support for this feature to be available on all future CPU generations (with the possible exception of embedded edge cases), so this default setting should make mistakes less likely and keep maintenance effort lower. (Besides, enabling the support where it doesn't work fails fast, whereas keeping it disabled where it could work is an inefficiency that can easily go overlooked for a long time.) While this is technically a CPU feature, not a northbridge feature, we support a lot more individual CPUs than northbridges in the pre-SoC era, and they tend to be closely coupled anyway. So select the option at the northbridge level for older CPUs to keep things simpler.

Add a new proximity type to represent the sub-NUMA cluster (SNC). This patch adds necessary Xeon-SP common code level support for SNC support. When SNC on, each SNC cluster will have a proximity domain. DIMMs and CPU cores are attached to SNC proximity domains instead of the processor proximity domains. With SNC, there are 3 types of proximity domains, PD_TYPE_PROCESSOR, PD_TYPE_GENERIC_INITIATOR and PD_TYPE_CLUSTER. proximity domain type checks in Xeon-SP codes are updated to correctly handle the adding of the new type. This patch doesn't actually enable SNC. To fully enable SNC, SoC codes need to override soc_get_cluster_count(), soc_set_cpu_node_ id() and memory_to_pd(), and call soc_set_cpu_node_id() in its per-CPU init routine.

2024-04-29soc/intel/cmn/graphics: Make DDI-A 4 lanes configurableAngel Pons
As described in Intel document 336464 (8th gen S series datasheet volume 1), the CPU's 4 eDP lanes can be bifurcated, so that DDI-A (eDP) ends up with 2 lanes, and DDI-E (DP, typically used for VGA) has the remaining 2 lanes. This lets mainboards provide a VGA output without sacrificing one of the main 4-lane DDIs. Newer platforms seem to be lacking this. However, the way this is structured in coreboot does not allow boards to choose whether bifurcation should be enabled. Most boards in the tree do not use DDI-E (it doesn't exist on mobile platforms), but there are some boards (e.g. hp/280_g2) that use DDI-E and a DP-to-VGA converter chip to provide a VGA output. Replace `SOC_INTEL_CONFIGURE_DDI_A_4_LANES` with two new Kconfig options to allow boards to decide. Use `SOC_INTEL_GFX_HAVE_DDI_A_BIFURCATION` to specify whether a platform supports DDI-A bifurcation at all (do nothing otherwise, maintaining the original code's behaviour). If bifurcation is supported, the `SOC_INTEL_GFX_ENABLE_DDI_E_BIFURCATION` is used to clear or set the `DDI_A_4_LANES` bit in the `DDI_BUF_CTL_A` register.
