2020-02-12arch/arm64/Makefile.inc: Avoid # in variable definitionNico Huber
Interpretation if # starts a comment inside a variable definition varies between GNU make versions. Use a wildcard to match the first # and use `sed` instead of `grep | cut` to avoid unbalanced quoting chars. Tested with GNU make 4.2.1 and 4.3. Both produce the same output as 4.2.1 did before the patch.

2020-01-28commonlib: Add commonlib/bsdJulius Werner
This patch creates a new commonlib/bsd subdirectory with a similar purpose to the existing commonlib, with the difference that all files under this subdirectory shall be licensed under the BSD-3-Clause license (or compatible permissive license). The goal is to allow more code to be shared with libpayload in the future. Initially, I'm going to move a few files there that have already been BSD-licensed in the existing commonlib. I am also exracting most contents of the often-needed <commonlib/helpers.h> as long as they have either been written by me (and are hereby relicensed) or have an existing equivalent in BSD-licensed libpayload code. I am also relicensing <commonlib/compression.h> (written by me) and <commonlib/compiler.h> (same stuff exists in libpayload). Finally, I am extracting the cb_err error code definitions from <types.h> into a new BSD-licensed header so that future commonlib/bsd code can build upon a common set of error values. I am making the assumption here that the enum constants and the half-sentence fragments of documentation next to them by themselves do not meet the threshold of copyrightability.

2019-12-11printf: Automatically prefix %p with 0xJulius Werner
According to the POSIX standard, %p is supposed to print a pointer "as if by %#x", meaning the "0x" prefix should automatically be prepended. All other implementations out there (glibc, Linux, even libpayload) do this, so we should make coreboot match. This patch changes vtxprintf() accordingly and removes any explicit instances of "0x%p" from existing format strings. How to handle zero padding is less clear: the official POSIX definition above technically says there should be no automatic zero padding, but in practice most other implementations seem to do it and I assume most programmers would prefer it. The way chosen here is to always zero-pad to 32 bits, even on a 64-bit system. The rationale for this is that even on 64-bit systems, coreboot always avoids using any memory above 4GB for itself, so in practice all pointers should fit in that range and padding everything to 64 bits would just hurt readability. Padding it this way also helps pointers that do exceed 4GB (e.g. prints from MMU config on some arm64 systems) stand out better from the others.

2019-12-05arm64: Print a char to UART early in exception handlerJulius Werner
Over time our printk() seems to acquire more and more features... which is nice, but it also makes it a little less robust when something goes wrong. If the wrong global is trampled by some buffer overflow, it suddenly doesn't print anymore. It would be nice to have at least some way to tell that we triggered a real exception in that case. With this patch, arm64 exceptions will print a '!' straight to the UART before trying any of the more fancy printk() stuff. It's not much but it should tell the difference between an exception and a hang and hopefully help someone dig in the right direction sooner. This violates loglevels (which is part of the point), but presumably when you have a fatal exception you shouldn't care about that anymore.

2019-12-05arm64: Bump exception stack size to 2KBJulius Werner
To avoid trampling over interesting exception artifacts on the real stack, our arm64 systems switch to a separate exception stack when entering an exception handler. We don't want that to use up too much SRAM so we just set it to 512 bytes. I mean it just prints a bunch of registers, how much stack could it need, right? Quite a bit it turns out. The whole vtxprintf() call stack goes pretty deep, and aarch64 generally seems to be very generous with stack space. Just the varargs handling seems to require 128 bytes for some reason, and the other stuff adds up too. In the end the current implementation takes 1008 bytes, so bump the exception stack size to 2K to make sure it fits.

Arm CPUs have always had an odd feature that allows you to mask not only true interrupts, but also "external aborts" (memory bus errors from outside the CPU). CPUs usually have all of these masked after reset, which we quickly learned was a bad idea back when bringing up the first arm32 systems in coreboot. Masking external aborts means that if any of your firmware code does an illegal memory access, you will only see it once the kernel comes up and unmasks the abort (not when it happens). Therefore, we always unmask everything in early bootblock assembly code. When arm64 came around, it had very similar masking bits and we did the same there, thinking the issue resolved. Unfortunately Arm, in their ceaseless struggle for more complexity, decided that having a single bit to control this masking behavior is no longer enough: on AArch64, in addition to the PSTATE.DAIF bits that are analogous to arm32's CPSR, there are additional bits in SCR_EL3 that can override the PSTATE setting for some but not all cases (makes perfect sense, I know...). When aborts are unmasked in PSTATE, but SCR.EA is not set, then synchronous external aborts will cause an exception while asynchronous external aborts will not. It turns out we never intialize SCR in coreboot and on RK3399 it comes up with all zeroes (even the reserved-1 bits, which is super weird). If you get an asynchronous external abort in coreboot it will silently hide in the CPU until BL31 enables SCR.EA before it has its own console handlers registered and silently hangs. This patch resolves the issue by also initializing SCR to a known good state early in the bootblock. It also cleans up some bit defintions and slightly reworks the DAIF unmasking... it doesn't actually make that much sense to unmask anything before our console and exception handlers are up. The new code will mask everything until the exception handler is installed and then unmask it, so that if there was a super early external abort we could still see it. (Of course there are still dozens of other processor exceptions that could happen which we have no way to mask.)

This patch adds an optional pre-RAM cache for the FMAP which most platforms should be able to use, complementing the recently added post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP about half a dozen times from flash in verstage, which will all be coalesced into a single read with this patch. It will also help future vboot improvements since when FMAP reads become "free" vboot doesn't need to keep track of so much information separately. In order to make sure we have a single, well-defined point where the new cache is first initialized, eliminate the build-time hardcoding of the CBFS section offsets, so that all CBFS accesses explicitly read the FMAP. Add FMAP_CACHEs to all platforms that can afford it (other than the RISC-V things where I have no idea how they work), trying to take the space from things that look like they were oversized anyway (pre-RAM consoles and CBFS caches).

2019-11-03arch/arm64: Pass cbmem_top to ramstage via calling argumentArthur Heymans
This solution is very generic and can in principle be implemented on all arch/soc. Currently the old infrastructure to pass on information from romstage to ramstage is left in place and will be removed in a follow-up commit. Nvidia Tegra will be handled in a separate patch because it has a custom ramstage entry. Instead trying to figure out which files can be removed from stages and which cbmem_top implementations need with preprocessor, rename all cbmem_top implementation to cbmem_top_romstage. Mechanisms set in place to pass on information from rom- to ram-stage will be replaced in a followup commit.

2019-11-03arch/x86: Use the stage argument to implement cbmem_topArthur Heymans
Currently all stages that need cbmem need an implementation of a cbmem_top function. On FSP and AGESA platforms this proves to be painful and a pointer to the top of lower memory if often passed via lower memory (e.g. EBDA) or via a PCI scratchpad register. The problem with writing to lower memory is that also need to be written on S3 as one cannot assume it to be still there. Writing things on S3 is always a fragile thing to do. A very generic solution is to pass cbmem_top via the program argument. It should be possible to implement this solution on every architecture. Instead trying to figure out which files can be removed from stages and which cbmem_top implementations need with preprocessor, rename all cbmem_top implementation to cbmem_top_romstage. TESTED on qemu-x86.

2019-11-03cpu/x86/tsc: Flip and rename TSC_CONSTANT_RATE to UNKNOWN_TSC_RATEKyösti Mälkki
The x86 timers are a bit of a mess. Cases where different stages use different counters and timestamps use different counters from udelays. The original intention was to only flip TSC_CONSTANT_RATE Kconfig to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those counters do run with a constant rate but we just lack tsc_freq_mhz() implementation for three platforms. Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a slow run of calibrate_tsc_with_pit(). This is easy enough to fix with followup implementation of tsc_freq_mhz() for the platforms. Implementations with LAPIC_MONOTONIC_TIMER typically will not have tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However, as they don't use TSC for udelay() the slow calibrate_tsc_with_pit() is avoided. Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900 claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch that romstage to use UDELAY_TSC.
