2021-03-17cbfs: Replace more instances of cbfs_boot_locate() with newer APIsJulius Werner
In pursuit of the eventual goal of removing cbfs_boot_locate() (and direct rdev access) from CBFS APIs, this patch replaces all remaining "simple" uses of the function call that can easily be replaced by the newer APIs (like cbfs_load() or cbfs_map()). Some cases of cbfs_boot_locate() remain that will be more complicated to solve.

2021-03-17program_loading: Replace prog_rdev() with raw start pointer and sizeJulius Werner
Since prog_locate() was eliminated, prog_rdev() only ever represents the loaded program in memory now. Using the rdev API for this is unnecessary if we know that the "device" is always just memory. This patch changes it to be represented by a simple pointer and size. Since some code still really wants this to be an rdev, introduce a prog_chain_rdev() helper to translate back to that if necessary.

2021-01-15cpu/x86/mpinit: Serialize microcode updates for HT threadsPatrick Rudolph
This change affects Intel CPUs only. As most platforms are doing uCode update using FIT, they aren't affected by this code either. Update microcode in MP-init using a single spinlock when running on a Hyper-Threading enabled CPU on pre FIT platforms. This will slow down the MP-init boot flow. Intel SDM and various BWGs specify to use a semaphore to update microcode on one thread per core on Hyper-Threading enabled CPUs. Due to this complex code would be necessary to determine the core #ID, initializing and picking the right semaphore out of CONFIG_MAX_CPUS / 2. Instead use the existing global spinlock already present in MPinit code. Assuming that only pre-FIT platforms with Hyper-Threading enabled and at most 8 threads will ever run into this condition, the boot delay is negligible. This change is a counterproposal to the previous published patch series being much more unsophisticated.

2020-11-09cpu/x86/smm: Add a common save state handlingArthur Heymans
Currently coreboot has limited use for the SMM save state. Typically the only thing needed is to get or set a few registers and to know which CPU triggered the SMI (typically via an IO write). Abstracting away different SMM save states would allow to put some SMM functionality like the SMMSTORE entry in common places. To save place platforms can select different SMM save sate ops that should be implemented. For instance AMD platforms don't need Intel SMM save state handling. Some platforms can encounter CPUs with different save states, which the code then handles at runtime by comparing the SMM save state revision which is located at the same offset for all SMM save state types.

2020-08-15cpu/x86/smm: Introduce SMM module loader version 2Rocky Phagura
Xeon-SP Skylake Scalable Processor can have 36 CPU threads (18 cores). Current coreboot SMM is unable to handle more than ~32 CPU threads. This patch introduces a version 2 of the SMM module loader which addresses this problem. Having two versions of the SMM module loader prevents any issues to current projects. Future Xeon-SP products will be using this version of the SMM loader. Subsequent patches will enable board specific functionality for Xeon-SP. The reason for moving to version 2 is the state save area begins to encroach upon the SMI handling code when more than 32 CPU threads are in the system. This can cause system hangs, reboots, etc. The second change is related to staggered entry points with simple near jumps. In the current loader, near jumps will not work because the CPU is jumping within the same code segment. In version 2, "far" address jumps are necessary therefore protected mode must be enabled first. The SMM layout and how the CPUs are staggered are documented in the code. By making the modifications above, this allows the smm module loader to expand easily as more CPU threads are added. TEST=build for Tiogapass platform under OCP mainboard. Enable the following in Kconfig. select CPU_INTEL_COMMON_SMM select SOC_INTEL_COMMON_BLOCK_SMM select SMM_TSEG select HAVE_SMI_HANDLER select ACPI_INTEL_HARDWARE_SLEEP_VALUES Debug console will show all 36 cores relocated. Further tested by generating SMI's to port 0xb2 using XDP/ITP HW debugger and ensured all cores entering and exiting SMM properly. In addition, booted to Linux 5.4 kernel and observed no issues during mp init.

2020-06-16x86/lapic: Set EXTINT on BSP onlyZheng Bao
When Linux is booted, the kernel reports "do_IRQ: 1.55 No irq handler for vector" So far it comes with payloads SeaBIOS and depthcharge, not with Grub. We assume Grub does something to avoid this problem. AMD bug tracker system (JIRA PLAT-21393) says the APs can not be set EXTINT delivery mode. In Intel 64 and IA-32 Architectures Software Developer’s Manual volume 3A, see chapter 10.5.1 Local Vector Table, it says: "The APIC architecture supports only one ExtINT source in a system, usually contained in the compatibility bridge. Only one processor in the system should have an LVT entry configured to use the ExtINT delivery mode." Tested on mandolin (Picasso) board, the error in dmesg is gone. The bug 153677727 has two parts. 1. Soft lockup 2. do_IRQ 1.55.

When adding XIP stages on x86, the -P parameter was used to pass a page size that covers the entire file to add. The same can now be achieved with --pow2page and we no longer need to define a static Konfig for the purpose. TEST: Build asus/p2b and lenovo/x60 with "--pow2page -v -v" and inspect the generated make.log files. The effective pagesize is reduced from 64kB to 16kB for asus/p2b giving more freedom for the stage placement inside CBFS. Pagesize remained at 64kB for lenovo/x60.

The AMD64 Architecture Programmer's Manual, Volume 2: Systems Programming says the following about variable MTRRs: Variable Range Size and Alignment. The size and alignment of variable memory-ranges (MTRRs) and I/O ranges (IORRs) are restricted as follows: * The boundary on which a variable range is aligned must be equal to the range size. For example, a memory range of 16 Mbytes must be aligned on a 16-Mbyte boundary (i.e., naturally aligned). * The range size must be a power of 2 (2^n , 52 > n > 11), with a minimum allowable size of 4 Kbytes. For example, 4 Mbytes and 8 Mbytes are allowable memory range sizes, but 6 Mbytes is not allowable. Print out errors if these conditions are violated. I didn't assert since `set_var_mtrr` can be used in boot block before the serial console is enabled.

2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2020-03-15nb/intel/nehalem: Rename to ironlakeAngel Pons
The code is for Arrandale CPUs, whose System Agent is Ironlake. This change simply replaces `nehalem` with `ironlake` and `NEHALEM` with `IRONLAKE`. The remaining `Nehalem` cases are handled later, as changing some of them would impact the resulting binary. Tested with BUILD_TIMELESS=1 without adding the configuration options into the binary, and packardbell/ms2290 does not change.

2020-03-07cpu/x86/smm: Add smm_size to relocatable smmstubArthur Heymans
To mitigate against sinkhole in software which is required on pre-sandybridge hardware, the smm entry point needs to check if the LAPIC base is between smbase and smbase + smmsize. The size needs to be available early so add them to the relocatable module parameters. When the smmstub is used to relocate SMM the default SMM size 0x10000 is provided. On the permanent handler the size provided by get_smm_info() is used.

Originally, this patch made 'BIOS' uppercase in the referenced comment and converted the C++ style to be consistent with the remainder of the function. Somewhere, the 'BIOS' became uppercase creating a merge conflict. Now this CL converts the C++ style to be consistent with the remainder of the comments. Signed-off-by: Eugene D.
