2021-07-26arch/x86,lib/thread: Enable thread support in romstageRaul E Rangel
This change does the following: * Pushes the cpu_info struct into the top of the stack (just like c_start.S). This is required so the cpu_info function works correctly. * Adds the thread.c to the romstage build. I only enabled this for romstage since I haven't done any tests in other stages, but in theory it should work for other stages.

2021-07-26arch/x86,cpu/x86/mp_init: Switch cpu_info index type to size_tRaul E Rangel
The alignment for `struct cpu_info` is wrong on x86_64. c_start.S uses the `push` instruction when setting up the cpu_info struct. This instruction will push 8 bytes but `unsigned int` is 4 bytes. By making it a `size_t` we get the correct size for both x86_32 and x86_64.

2021-07-09ppc64/byteorder.h: define use of big endianKrystian Hebel
All of the build configuration is set to produce big endian image on PPC64. In addition, the toolchain produced by coreboot-sdk does not include little endian libraries so it is not possible to build LE image even when that configuration is changed. This patch changes byte order definition which is required for proper work of functions that deal with endianness, like read_{le,be}*() or {le,be}*toh(). It also revealed bugs related to the endianness on BE targets that are addressed in the following patches.

2021-07-07arch/x86: Save resume vector to stack in x86_64 modeIru Cai
In x86_64, the first function parameter is passed in rdi register, and the 32-bit code after exiting long mode reads the resume vector in 4(%esp), so it's needed to save the resume vector from rdi to 4(%rsp). Also note that the function attribute "regparm" only works on x86-32 targets according to the GCC manual, so "asmlinkage" doesn't change the ABI of an x86_64 function. Tested on HP EliteBook 2560p. The laptop can resume from S3 in x86_64 mode after this change.

APIC Serial Bus pins were removed with ICH5 already, so a choice 'irq_on_fsb = 0' would not take effect. The related register BOOT_CONFIG 0x3 is also not documented since ICH5. For emulation/qemu-q35 with ICH9 the choice INTERRUPT_ON_APIC_BUS was wrong and ignored as BOOT_CONFIG register emulation was never implemented. For ICH4 and earlier, the choice to use FSB can be made based on the installed CPU model but this is now just hardwired to match P4 CPUs of aopen/dxplplusu. For sb/intel/i82371eb register BOOT_CONFIG 0x3 is also not defined and the only possible operation mode there is APIC Serial Bus, which requires no configuration.

2021-06-15treewide: Disable R_AMD64_32S relocation supportPatrick Rudolph
This fixes a hard to debug hang that could occur in any stage, but in the end it follows simple rules and is easy to fix. In long mode the 32bit displacement addressing used on 'mov' and 'lea' instructions is sign-extended. Those instructions can be found using readelf on the stage and searching for relocation type R_X86_64_32S. The sign extension is no issue when either running in protected mode or the code module and thus the address is below 2GiB. If the address is greater than 2GiB, as usually the case for code in TSEG, the higher address bits [64:32] are all set to 1 and the effective address is pointing to memory not paged. Accessing this memory will cause a page fault, which isn't handled either. To prevent such problems - disable R_AMD64_32S relocations in rmodtool - add comment explaining why it's not allowed - use the pseudo op movabs, which doesn't use 32bit displacement addressing - Print a useful error message if such a reloc is present in the code Fixes a crash in TSEG and when in long mode seen on Intel Sandybridge.

The CBFS mcache size default was eyeballed to what should be "hopefully enough" for most users, but some recent Chrome OS devices have already hit the limit. Since most current (and probably all future) x86 chipsets likely have the CAR space to spare, let's just double the size default for all supporting chipsets right now so that we hopefully won't run into these issues again any time soon. The CBFS_MCACHE_RW_PERCENTAGE default for CHROMEOS was set to 25 under the assumption that Chrome OS images have historically always had a lot more files in their RO CBFS than the RW (because l10n assets were only in RO). Unfortunately, this has recently changed with the introduction of updateable assets. While hopefully not that many boards will need these, the whole idea is that you won't know whether you need them yet at the time the RO image is frozen, and mcache layout parameters cannot be changed in an RW update. So better to use the normal 50/50 split on Chrome OS devices going forward so we are prepared for the eventuality of needing RW assets again. The RW percentage should really also be menuconfig-controllable, because this is something the user may want to change on the fly depending on their payload requirements. Move the option to the vboot Kconfigs because it also kinda belongs there anyway and this makes it fit in better in menuconfig. (I haven't made the mcache size menuconfig-controllable because if anyone needs to increase this, they can just override the default in the chipset Kconfig for everyone using that chipset, under the assumption that all boards of that chipset have the same amount of available CAR space and there's no reason not to use up the available space. This seems more in line with how this would work on non-x86 platforms that define this directly in their memlayout.ld.) Also add explicit warnings to both options that they mustn't be changed in an RW update to an older RO image.

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.

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.
