2018-12-04acpi_pld: Make it easier to define the ACPI USB device groupsDuncan Laurie
The Linux kernel can use the ACPI _PLD group information to determine peer ports. Currently to define the group information the devicetree must provide a complete _PLD structure. This change pulls the group information into a separate structure that can be defined in devicetree. This makes it easier to set for USB devices in devicetree that do not need a full custom PLD. This was tested on a sarien board with the USB devices defined by verifying that the USB 2/3 ports are correctly identified with their peer in sysfs.

2018-11-23arch/x86: drop special case cbfs locatorPatrick Georgi
CBFS used to have a special region for the x86 bootblock, which also contained a pointer to a CBFS master header, which describes the layout of the CBFS. Since we adopted other architectures, we got rid of the bootblock region as a separate entity and add the x86 bootblock as a CBFS file now. The master header still exists for compatibility with old cbfstool versions, but it's neatly wrapped in either the bootblock file or in a file carefully crafted at the right location (on all other architectures). All the layout information we need is now available from FMAP, a core part of a contemporary coreboot image, even on x86, so we can just use the generic master header locator in src/lib/cbfs.c and get rid of the special version. Among the advantages: the x86 header locator reduced the size of the CBFS by 64 bytes assuming that there's the bootblock region of at least that size - this breaks assumptions elsewhere (eg. when walking CBFS in cbfs_boot_locate() because the last file, the bootblock, will exceed the CBFS region as seen by coreboot (since it's CBFS - 64bytes).

Change 76ab2b7 ("arch/x86: allow global .bss objects without CAR_GLOBAL") allowed use of global .bss objects and hence moved around the macros resulting in car_active returning 0 even for those boards where CAR is actually active but do not require global migration. This resulted in boards getting stuck when doing a reset in verstage because the code flow incorrectly assumed that there was no CAR active and hence triggered a cache invalidate.

2018-10-25selfboot: create selfboot_check function, remove check paramRonald G. Minnich
The selfboot function was changed at some point to take a parameter which meant "check the allocated descriptors to see if they target regions of real memory." The region check had to be buried deep in the last step of loading since that is where those descriptors were created and used. An issue with the use of the parameter was that it was not possible for compilers to easily divine whether the check code was used, and it was hence possible for the code, and its dependencies, to be compiled in even if never used (which caused problems for the rampayload code). Now that bounce buffers are gone, we can hoist the check code to the outermost level. Further, by creating a selfload_check and selfload function, we can make it easy for compilers to discard unused code: if selfload_check is never called, all the code it uses can be discarded too.

2018-10-12libpayload: arm64: Conform to new coreboot lib_helpers.h and assume EL2Julius Werner
This patch adds the new, faster architectural register accessors to libpayload that were already added to coreboot in CB:27881. It also hardcodes the assumption that coreboot payloads run at EL2, which has already been hardcoded in coreboot with CB:27880 (see rationale there). This means we can drop all the read_current/write_current stuff which added a lot of unnecessary helpers to check the current exception level. This patch breaks payloads that used read_current/write_current accessors, but it seems unlikely that many payloads deal with this stuff anyway, and it should be a trivial fix (just replace them with the respective _el2 versions). Also add accessors for a couple of more registers that are required to enable debug mode while I'm here.

2018-10-11selfboot: remove bounce buffersRonald G. Minnich
Bounce buffers used to be used in those cases where the payload might overlap coreboot. Bounce buffers are a problem for rampayloads as they need malloc. They are also an artifact of our x86 past before we had relocatable ramstage; only x86, out of the 5 architectures we support, needs them; currently they only seem to matter on the following chipsets: src/northbridge/amd/amdfam10/Kconfig src/northbridge/amd/lx/Kconfig src/northbridge/via/vx900/Kconfig src/soc/intel/fsp_baytrail/Kconfig src/soc/intel/fsp_broadwell_de/Kconfig The first three are obsolete or at least could be changed to avoid the need to have bounce buffers. The last two should change to no longer need them. In any event they can be fixed or pegged to a release which supports them. For these five chipsets we change CONFIG_RAMBASE from 0x100000 (the value needed in 1999 for the 32-bit Linux kernel, the original ramstage) to 0xe00000 (14 Mib) which will put the non-relocatable x86 ramstage out of the way of any reasonable payload until we can get rid of it for good. 14 MiB was chosen after some discussion, but it does fit well: o Fits in the 16 MiB cacheable range coreboot sets up by default o Most small payloads are well under 14 MiB (even kernels!) o Most large payloads get loaded at 16 MiB (especially kernels!) With this change in place coreboot correctly still loads a bzImage payload. Werner reports that the 0xe00000 setting works on his broadwell systems.

Events reported via BERT are Generic Error Data, and are constructed as follows (see ACPI and UEFI specs for reference): * Each event begins with a Generic Error Status Block, which may contain zero or more Generic Data Entries * Each Generic Data Entry is identifiable by its Section Type field, and the data structures associated are also in the UEFI spec. * The GUIDs are listed in the Section Type field of the CPER Section Descriptor structure. BERT doesn't use this structure but simply uses its GUIDs. * Data structures used in the Generic Data Entry are named as Error Sections in the UEFI spec. * Some sections may optionally include a variable number of additional structures, e.g. an IA32/X64 processor error can report error information as well as machine contexts. It is worth noting that the Linux kernel (as of v4.4) does not attempt to parse IA32/X64 sections, and opts to hexdump them instead.

2018-08-17arm64: Factor out common parts of romstage execution flowJulius Werner
The romstage main() entry point on arm64 boards is usually in mainboard code, but there are a handful of lines that are always needed in there and not really mainboard specific (or chipset specific). We keep arguing every once in a while that this isn't ideal, so rather than arguing any longer let's just fix it. This patch moves the main() function into arch code with callbacks that the platform can hook into. (This approach can probably be expanded onto other architectures, so when that happens this file should move into src/lib.) Tested on Cheza and Kevin. I think the approach is straight-forward enough that we can take this without testing every board. (Note that in a few cases, this delays some platform-specific calls until after console_init() and exception_init()... since these functions don't really take that long, especially if there is no serial console configured, I don't expect this to cause any issues.)

2018-08-13arm64: mmu: Spot check security state for TTB mappingJulius Werner
Since commit 372d0ff1d1 (arch/arm64: mmu: Spot check TTB memory attributes), we already check the memory attributes that the TTB region is mapped with to avoid configuration mistakes that cause weird issues (because the MMU walks the page tables with different memory attributes than they were written with). Unfortunately, we only checked cachability, but the security state attribute is just as important for this (because it is part of the cache tag, meaning that a cache entry created by accessing the non-secure mapping won't be used when trying to read the same address through a secure mapping... and since AArch64 page table walks are cache snooping and we rely on that behavior, this can lead to the MMU not seeing the new page table entries we just wrote). This patch adds the check for security state and cleans up that code a little.

2018-08-10arm64: Turn architectural register accessors into inline functionsJulius Werner
Accesses to architectural registers should be really fast -- they're just registers, after all. In fact, the arm64 architecture uses them for some timing-senstive uses like the architectural timer. A read should be: one instruction, no data dependencies, done. However, our current coreboot framework wraps each of these accesses into a separate function. Suddenly you have to spill registers on a stack, make a function call, move your stack pointer, etc. When running without MMU this adds a significant enough delay to cause timing problems when bitbanging a UART on SDM845. This patch replaces all those existing functions with static inline definitions in the header so they will get reduced to a single instruction as they should be. Also use some macros to condense the code a little since they're all so regular, which should make it easier to add more in the future. This patch also expands all the data types to uint64_t since that's what the actual assembly instruction accesses, even if the register itself only has 32 bits (the others will be ignored by the processor and set to 0 on read). Arm regularly expands registers as they add new bit fields to them with newer iterations of the architecture anyway, so this just prepares us for the inevitable.

2018-08-10arm64: Drop checks for current exception level, hardcode EL3 assumptionJulius Werner
When we first created the arm64 port, we weren't quite sure whether coreboot would always run in EL3 on all platforms. The AArch64 A.R.M. technically considers this exception level optional, but in practice all SoCs seem to support it. We have since accumulated a lot of code that already hardcodes an implicit or explicit assumption of executing in EL3 somewhere, so coreboot wouldn't work on a system that tries to enter it in EL1/2 right now anyway. However, some of our low level support libraries (in particular those for accessing architectural registers) still have provisions for running at different exception levels built-in, and often use switch statements over the current exception level to decide which register to access. This includes an unnecessarily large amount of code for what should be single-instruction operations and precludes further optimization via inlining. This patch removes any remaining code that dynamically depends on the current exception level and makes the assumption that coreboot executes at EL3 official. If this ever needs to change for a future platform, it would probably be cleaner to set the expected exception level in a Kconfig rather than always probing it at runtime.
