2021-01-24soc/intel/xeon_sp/cpx: Account for 'rc' heap managerArthur Heymans
The xeon_sp/cpx has a second 'rc' heap inside FSP-M that is statically allocated at the start of CAR. This breaks FSP 2.0 specification. This can be worked around in the linker scripts to make sure coreboot and FSP-M don't fight over the same memory. Tested - on ocp/deltalake: boot and the "Smashed stack detected in romstage!" message at the end of romstage is gone. - qemu/i440fx: BUILD_TIMELESS=1 results in the same binary.

2021-01-07arch/x86: Move prologue to .init sectionKyösti Mälkki
For arch/x86 the realmode part has to be located within the same 64 KiB as the reset vector. Some older intel platforms also require 4 KiB alignment for _start16bit. To enforce the above, and to separate required parts of .text without matching *(.text.*) rules in linker scripts, tag the pre-C environment assembly code with section .init directive. Description of .init section for ELF: This section holds executable instructions that contribute to the process initialization code. When a program starts to run, the system arranges to execute the code in this section before calling the main program entry point (called main for C programs).

2020-12-08coreboot tables: Add SPI flash memory map windows to coreboot tablesFurquan Shaikh
This change adds details about the memory map windows to translate addresses between SPI flash space and host address space to coreboot tables. This is useful for payloads to setup the translation using the decode windows already known to coreboot. Until now, there was a single decode window at the top of 4G used by all x86 platforms. However, going forward, platforms might support more decode windows and hence in order to avoid duplication in payloads this information is filled in coreboot tables. `lb_spi_flash()` is updated to fill in the details about these windows by making a call to `spi_flash_get_mmap_windows()` which is implemented by the driver providing the boot media mapping device.

2020-12-03x86: Put bootblock startup code into .text._start sectionJulius Werner
The initial bootblock assembly code on x86 is just put into the .text section, which just happens to come before all the individual .text.* function sections in the program.ld script. So it tends to be at the start of the image, but if you inserted another linker script section with contents before .text, it would cause a problem. (I'm not sure if it's an architectural requirement for _start16bit to come at the start of the image, but at least its 4K alignment requirement would waste a lot of space if it didn't.) This patch moves the section to .text._start which is the name other architectures use for the code they want in the very front of the image and which is listed first in program.ld.

2020-12-02cbfs: Simplify load/map API names, remove type argumentsJulius Werner
This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file() to cbfs_map() and cbfs_load() respectively. This is supposed to be the start of a new, better organized CBFS API where the most common operations have the most simple and straight-forward names. Less commonly used variants of these operations (e.g. cbfs_ro_load() or cbfs_region_load()) can be introduced later. It seems unnecessary to keep carrying around "boot" in the names of most CBFS APIs if the vast majority of accesses go to the boot CBFS (instead, more unusual operations should have longer names that describe how they diverge from the common ones). cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly reap mappings when desired. A few new cbfs_unmap() calls are added to generic code where it makes sense, but it seems unnecessary to introduce this everywhere in platform or architecture specific code where the boot medium is known to be memory-mapped anyway. In fact, even for non-memory-mapped platforms, sometimes leaking a mapping to the CBFS cache is a much cleaner solution than jumping through hoops to provide some other storage for some long-lived file object, and it shouldn't be outright forbidden when it makes sense. Additionally, remove the type arguments from these function signatures. The goal is to eventually remove type arguments for lookup from the whole CBFS API. Filenames already uniquely identify CBFS files. The type field is just informational, and there should be APIs to allow callers to check it when desired, but it's not clear what we gain from forcing this as a parameter into every single CBFS access when the vast majority of the time it provides no additional value and is just clutter.

2020-09-03memory_info: add max_speed_mts and configured_speed_mtsRob Barnes
ddr_frequency is ambiguous and is interpreted differently in several places. Instead of renaming this field, this deprecates it and adds two new fields with unambiguous naming, max_speed_mts and configured_speed_mts. smbios.c falls back to using ddr_frequency when either of these fields are 0. The same value was being used for both configured memory speed and max memory speed in SMBIOS type 17, which is not accurate when configured speed is not the max speed.

Use 64bit GDT loading on x86_64 and force the assembler to generate a 64bit address load on the GDT. This will make sure no 32bit (signed) displacement op is being generated, which points to the wrong address in longmode.

2020-07-30smbios: Fix type 17 for Windows 10Patrick Rudolph
The `GetPhysicallyInstalledSystemMemory` API call, at least on Windows 10, returns an error if SMBIOS tables are invalid. Various tools use this API call and don't operate correctly if this fails. For example, the "Intel Processor Diagnostic Tool" program is affected. Windows then guesses the physical memory size by accumulating entries from the firmware-provided memory map, which results in a total memory size that is slightly lower than the actual installed memory capacity. To fix this issue, add the handle to a type 16 entry to all type 17 entries. Add new fields to struct memory_info and fill them in Intel common code. Use the introduced variables to fill type 16 in smbios.c and provide a handle to type 17 entries. Besides keeping the current behaviour on intel/soc/common platforms, the type 16 table is also emitted on platforms that don't explicitly fill it, by using the existing fields of struct memory_info. Tested on Windows 10: The GetPhysicallyInstalledSystemMemory API call doesn't return an error anymore and the installed memory is now being reported as 8192 MiB.

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.

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.
