2022-08-14broadwell: Decouple LPDDR3 DQ/DQS maps from `pei_data`Angel Pons
Introduce the `BROADWELL_LPDDR3` Kconfig option along with some wrapper code to allow mainboards using LPDDR3 DRAM to supply the DQ/DQS maps to chipset code without having to use `pei_data`. The only mainboard using LPDDR3 is Google Samus.

2022-08-14soc/intel/broadwell: Consolidate SPD handlingAngel Pons
Mainboards do not need to know about `pei_data` to tell northbridge code where to find the SPD data. As done on Haswell, add the `mb_get_spd_map` function and the `struct spd_info` type to retrieve SPD information from mainboard code without having to use `pei_data` in said mainboard code. Unlike Haswell MRC, Broadwell MRC uses all positions of the `spd_data` array, not just the first. The placeholder SPD address for memory-down seems to be different as well. Adapt the existing code to handle these variations. Once complete, the abstraction layer for both MRC binaries will have the same API.

2022-08-14broadwell: Move some MRC/refcode settings to devicetreeAngel Pons
There's no generic way to tell whether a mainboard has an EC or not. Making Kconfig symbols for these options seems overkill, too. So, just put them on the devicetree. Also, drop unnecessary assignments when the board's current value is zero, as the struct defaults to zero already.

2022-02-25arch/x86: consolidate HPET base address definitionsFelix Held
Both the HPET_BASE_ADDRESS define from arch/x86/include/arch/hpet.h and the HPET_ADDRESS Kconfig option define the base address of the HPET MMIO region which is 0xfed00000 on all chipsets and SoCs in the coreboot tree. Since these two different constants are used in different places that however might end up used in the same coreboot build, drop the Kconfig option and use the definition from arch/x86 instead. Since it's no longer needed to check for a mismatch of those two constants, the corresponding checks are dropped too.

Now that the console system itself will clearly differentiate loglevels, it is no longer necessary to explicitly add "ERROR: " in front of every BIOS_ERR message to help it stand out more (and allow automated tooling to grep for it). Removing all these extra .rodata characters should save us a nice little amount of binary size. This patch was created by running find src/ -type f -exec perl -0777 -pi -e 's/printk\(\s*BIOS_ERR,\s*"ERROR: /printk\(BIOS_ERR, "/gi' '{}' ';' and doing some cursory review/cleanup on the result.

2021-03-16cbfs: Remove prog_locate() for stages and rmodulesJulius Werner
This patch removes the prog_locate() step for stages and rmodules. Instead, the stage and rmodule loading functions will now perform the locate step directly together with the actual loading. The long-term goal of this is to eliminate prog_locate() (and the rdev member in struct prog that it fills) completely in order to make CBFS verification code safer and its security guarantees easier to follow. prog_locate() is the main remaining use case where a raw rdev of CBFS file data "leaks" out of cbfs.c into other code, and that other code needs to manually make sure that the contents of the rdev get verified during loading. By eliminating this step and moving all code that directly deals with file data into cbfs.c, we can concentrate the code that needs to worry about file data hashing (and needs access to cbfs_private.h APIs) into one file, making it easier to keep track of and reason about. This patch is the first step of this move, later patches will do the same for SELFs and other program types.

2021-03-15pciexp_device: Rewrite LTR configurationNico Huber
I was bugged by spurious "Failed to enable LTR" messages for years. Looking at the the current algorithm, it is flawed in multiple ways: * It looks like the author didn't know they implemented a recursive algorithm (pciexp_enable_ltr()) inside another recursive algorithm (pciexp_scan_bridge()). Thus, at every tree level, everything is run again for the whole sub- tree. * LTR is enabled no matter if `.set_ltr_max_latencies` is implemented or not. Leaving the endpoints' LTR settings at 0: They are told to always report zero tolerance. In theory, depending on the root-complex implementation, this may result in higher power consumption than without LTR messages. * `.set_ltr_max_latencies` is only considered for the direct parent of a device. Thus, even with it implemented, an endpoint below a (non-root) bridge may suffer from the 0 settings as described above. * Due to the double-recursive nature, LTR is enabled starting with the endpoints, then moving up the tree, while the PCIe spec tells us to do it in the exact opposite order. With the current implementation of pciexp_scan_bridge(), it is hard to hook anything in that runs for each device from top to bottom. So the proposed solution still adds some redundancy: First, for every device that uses pciexp_scan_bus(), we enable LTR if possible (see below). Then, when returning from the bus- scanning recursion, we enable LTR for every device and configure the maximum latencies (if supported). The latter runs again on all bridges, because it's hard to know if pciexp_scan_bus() was used for them. When to enable LTR: * For all devices that implement `.set_ltr_max_latencies`. * For all devices below a bridge that has it enabled already.
