2018-09-07arch/x86: Add BERT region support functionsMarshall Dawson
Add code for generating the region pointed to in an ACPI Boot Error Record Table. The BERT region must be reported as Reserved to the OSPM, so this code calls out to a system-specific region locator. cbmem is reported as type 16 and is not usable for the BERT region. 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.

There are no uses in common code anymore, so let's remove it from <arch/cache.h> for all architectures. arm64 still has an implementation and one reference, but they are not really needed since arch_program_segment_loaded() does the same thing already. Remove them. Leave it in arm(32) since there are several references (including in SoC code) that I don't feel like tracking down and testing right now.
