2020-06-19Kconfig: Escape variable to accommodate new Kconfig versionsPatrick Georgi
Kconfig 4.17 started using the $(..) syntax for environment variable expansion while we want to keep expansion to the build system. Older Kconfig versions (like ours) simply drop the escapes, not changing the behavior. While we could let Kconfig expand some of the variables, that only splits the handling in two places, making debugging harder and potentially messing with reproducible builds (e.g. when paths end up in configs), so escape them all.

2020-06-15Makefile.inc: Remove all-y with CONFIG_ARCH_xx guardsMartin Roth
The assumption up to this point was that if the system had an x86 processor, verstage would be running on the x86 processor. With running verstage on the PSP, that assumption no longer holds true, so exclude pieces of code that cause problems for verstage on the PSP. As a generalization, remove all-y for CONFIG_ARCH_xx guarded makefiles.

2020-06-13arch/x86: Add symbols for CAR MTRRs in linker scriptKyösti Mälkki
This allows to remove references to CONFIG_DCACHE_RAM entries in most cache_as_ram.S files. While Kconfig variable names appear for every stage, linker symbol names will only appear in stages they are valid in. Also, linker scripts have LOG2CEIL which comes in handy to enforce MTRR alignments.

2020-06-13treewide: Add Kconfig variable MEMLAYOUT_LD_FILEFurquan Shaikh
This change defines a Kconfig variable MEMLAYOUT_LD_FILE which allows SoC/mainboard to provide a linker file for the platform. x86 already provides a default memlayout.ld under src/arch/x86. With this new Kconfig variable, it is possible for the SoC/mainboard code for x86 to provide a custom linker file as well. Makefile.inc is updated for all architectures to use this new Kconfig variable instead of assuming memlayout.ld files under a certain path. All non-x86 boards used memlayout.ld under mainboard directory. However, a lot of these boards were simply including the memlayout from SoC. So, this change also updates these mainboards and SoCs to define the Kconfig as required. BUG=b:155322763 TEST=Verified that abuild with --timeless option results in the same coreboot.rom image for all boards.

Builds where RESET_X86_VECTOR is adjusted would create unintentionally large bootblock files since id section can move far away from .reset and .text. Some builds segfault or may try to create close to 4 GB large intermediate build objects. For cases where build is successful, id section would not reside within REGION(program) or REGION(bootblock). A proper fix to always place the ID data at the end of the coreboot.rom file is left as follow-up work. For now, just place id section below .reset.

2020-05-02acpi: Move ACPI table support out of arch/x86 (1/5)Furquan Shaikh
This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs. This is change 1/5 which moves .c files from arch/x86 to acpi/. The only acpi files that are still retained under arch/x86 are: a. acpi_s3.c: This doesn't really deal with ACPI tables. Also, there are some assumptions in there about SMM which will have to be resolved if this file needs to be moved to common code. b. acpi_bert_storage.c/bert_storage.h: This file is currently written specifically with x86 in mind. So, not moving the file for now. Motivation for this change: Not all stages on Picasso SoC are targeted for the same architecture. For example, verstage (if runs before bootblock) will be targeted for non-x86. This makes it difficult to add device tree to verstage which would be required to get to SoC configs from the tree. This is because the device tree on x86 platforms currently contains a lot of devices that require ACPI related enums and structs (like acpi_gpio, acpi_pld, acpi_dp and so on). Hence, this change removes all ACPI table support out of arch/x86.

2020-05-01arch/x86/acpi_device: Allow empty child referencesDuncan Laurie
Currently if a child table is created and added to a property list without adding any properties to that child it will generate an empty package. For example: struct acpi_dp *dsd = acpi_dp_new_table("_DSD"); struct acpi_dp *prop = acpi_dp_new_table("PROP"); acpi_dp_add_child(dsd, "dsd-prop", prop); acpi_dp_write(dsd); Results in an empty PROP package: Name (_DSD, Package (2) { ToUUID("dbb8e3e6-5886-4ba6-8795-1319f52a966b") Package (1) { Package (2) { "dsd-prop", "PROP" } } } Name (PROP, Package (0) { } Empty packages don't seem to be explicitly forbidden, but they don't serve a purpose with device properties. Instead, if packages without any properties or children are skipped then this empty package is not written and the added child property can refer to another property that is already defined. This allows creating property references to existing tables, which can save duplication and namespace collision issues with nested properties.

2020-04-29arch/x86: Implement RESET_VECTOR_IN_RAMFelix Held
Add support for devices with the reset vector pointing into DRAM. This is a specific implementation that assumes a paradigm of AMD Family 17h (a.k.a. "Zen"). Until the first ljmpl for protected mode, the core's state appears to software like other designs, and then the actual physical addressing becomes recognizable. These systems cannot implement cache-as-RAM as in more traditional x86 products. Therefore instead of reusing CAR names and variables, a substitute called "earlyram" is introduced. This change makes adjustments to CAR-aware files accordingly. Enable NO_XIP_EARLY_STAGES. The first stage is already in DRAM, and running subsequent stages as XIP in the boot device would reduce performance. Finally, add a new early_ram.ld linker file. Because all stages run in DRAM, they can be linked with their .data and .bss as normal, i.e. they don't need to rely on storage available only at a fixed location like CAR systems. The primary purpose of the early_ram.ld is to provide consistent locations for PRERAM_CBMEM_CONSOLE, TIMESTAMP regions, etc. across stages until cbmem is brought online.

2020-04-23rules.h: Rename ENV_VERSTAGE to ENV_SEPARATE_VERSTAGEJulius Werner
When CONFIG_SEPARATE_VERSTAGE=n, all verstage code gets linked into the appropriate calling stage (bootblock or romstage). This means that ENV_VERSTAGE is actually 0, and instead ENV_BOOTBLOCK or ENV_ROMSTAGE are 1. This keeps tripping up people who are just trying to write a simple "are we in verstage (i.e. wherever the vboot init logic runs)" check, e.g. for TPM init functions which may run in "verstage" or ramstage depending on whether vboot is enabled. Those checks will not work as intended for CONFIG_SEPARATE_VERSTAGE=n. This patch renames ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE to try to clarify that this macro can really only be used to check whether code is running in a *separate* verstage, and clue people in that they may need to cover the linked-in verstage case as well.
