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.

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.

2018-06-26arm64: Reimplement mmu_disable() in assemblyJulius Werner
Disabling the MMU with proper cache behavior is a bit tricky on ARM64: you can flush the cache first and then disable the MMU (like we have been doing), but then you run the risk of having new cache lines allocated in the tiny window between the two, which may or may not become a problem when those get flushed at a later point (on some platforms certain memory regions "go away" at certain points in a way that makes the CPU very unhappy if it ever issues a write cycle to them again afterwards). The obvious alternative is to first disable the MMU and then flush the cache, ensuring that every memory access after the flush already has the non-cacheable attribute. But we can't just flip the order around in the C code that we have because then those accesses in the tiny window in-between will go straight to memory, so loads may yield the wrong result or stores may get overwritten again by the later cache flush. In the end, this all shouldn't really be a problem because we can do both operations purely from registers without doing any explicit memory accesses in-between. We just have to reimplement the function in assembly to make sure the compiler doesn't insert any stack accesses at the wrong points.

2018-05-22Introduce bootblock self-decompressionJulius Werner
Masked ROMs are the silent killers of boot speed on devices without memory-mapped SPI flash. They often contain awfully slow SPI drivers (presumably bit-banged) that take hundreds of milliseconds to load our bootblock, and every extra kilobyte of bootblock size has a hugely disproportionate impact on boot speed. The coreboot timestamps can never show that component, but it impacts our users all the same. This patch tries to alleviate that issue a bit by allowing us to compress the bootblock with LZ4, which can cut its size down to nearly half. Of course, masked ROMs usually don't come with decompression algorithms built in, so we need to introduce a little decompression stub that can decompress the rest of the bootblock. This is done by creating a new "decompressor" stage which runs before the bootblock, but includes the compressed bootblock code in its data section. It needs to be as small as possible to get a real benefit from this approach, which means no device drivers, no console output, no exception handling, etc. Besides the decompression algorithm itself we only include the timer driver so that we can measure the boot speed impact of decompression. On ARM and ARM64 systems, we also need to give SoC code a chance to initialize the MMU, since running decompression without MMU is prohibitively slow on these architectures. This feature is implemented for ARM and ARM64 architectures for now, although most of it is architecture-independent and it should be relatively simple to port to other platforms where a masked ROM loads the bootblock into SRAM. It is also supposed to be a clean starting point from which later optimizations can hopefully cut down the decompression stub size (currently ~4K on RK3399) a bit more. NOTE: Bootblock compression is not for everyone. Possible side effects include trying to run LZ4 on CPUs that come out of reset extremely underclocked or enabling this too early in SoC bring-up and getting frustrated trying to find issues in an undebuggable environment. Ask your SoC vendor if bootblock compression is right for you.

2018-02-02arm64: Pass COREBOOT flag to ARM TF, always enable loggingJulius Werner
This patch changes the way coreboot builds ARM TF to pass the new COREBOOT flag introduced with the following pull request: https://github.com/ARM-software/arm-trusted-firmware/pull/1193 Since the new coreboot support code supports the CBMEM console, we need to always enable LOG_LEVEL INFO. Supporting platforms will parse the coreboot table to conditionally enable the serial console only if it was enabled in coreboot as well. Also remove explicit cache flushes of some BL31 parameters. Turns out we never really needed these because we already flush the whole cache when disabling the MMU, and we were already not doing it for most parameters.

coreboot and libpayload currently use completely different code to perform a full cache flush on ARM64, with even different function names. The libpayload code is closely inspired by the ARM32 version, so for the sake of overall consistency let's sync coreboot to that.

2017-03-28Remove libverstage as separate library and source file classJulius Werner
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are linked directly into the bootblock or the romstage. However, they're still compiled with a separate "libverstage" source file class, linked into an intermediate library and then linked into the final destination stage. There is no obvious benefit to doing it this way and it's unclear why it was chosen in the first place... there are, however, obvious disadvantages: it can result in code that is used by both libverstage and the host stage to occur twice in the output binary. It also means that libverstage files have their separate compiler flags that are not necessarily aligned with the host stage, which can lead to weird effects like <rules.h> macros not being set the way you would expect. In fact, VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86 because their libverstage code that gets compiled into the romstage sets ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to run pre-migration. This patch resolves these problems by removing the separate library. There is no more difference between the 'verstage' and 'libverstage' classes, and the source files added to them are just treated the same way a bootblock or romstage source files in configurations where the verstage is linked into either of these respective stages (allowing for the normal object code deduplication and causing those files to be compiled with the same flags as the host stage's files). Tested this whole series by booting a Kevin, an Elm (both with and without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

2016-11-17arm64: arm_tf: Do not build raw bl31.bin binaryJulius Werner
coreboot's build system picks up the BL31 image as an ELF from the ARM Trusted Firmware submodule and inserts it into CBFS. However, the generic 'bl31' build target we run in the ARM Trusted Firmware build system also generates a raw bl31.bin binary file. We don't need that binary, and with the recently added support for multiple non-contiguous program segments in BL31 it can grow close to 4GB in size (by having one section mapped near the start and one near the end of the address space). To avoid clogging up people's hard drives with 4GB of zeroes, let's only build the target we actually need.
