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.

2019-12-05arm64: Correctly unmask asynchronous SError interruptsJulius Werner
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.)

2019-11-14lib/fmap: Add optional pre-RAM cacheJulius Werner
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).

2019-11-05security/vboot: Removed vboot_prepare from vboot_locatorWim Vervoorn
When prog_locate() is called in the stage VBOOT is starting from and the image to be loaded is not the target image vboot_prepare() may be called too early. To prevent this vboot_prepare() is removed from the vboot_locator structure. This allows more control over the start of the vboot logic. To clarify the change the vboot_prepare() has been renamed to vboot_run_logic() and calls to initialize vboot have been added at the following places: postcar_loader: when VBOOT starts in ROMSTAGE romstage_loader: when VBOOT starts in BOOTBLOCK ramstage_loader: when VBOOT starts in ROMSTAGE BUG=N/A TEST=tested on facebook fbg1701 Change-Id: Id5e8fd78458c09dd3896bfd142bd49c2c3d686df Signed-off-by: Wim Vervoorn <wvervoorn@eltan.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/36543 Reviewed-by: Frans Hendriks <fhendriks@eltan.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
2019-11-04cpu/qemu-x86: Add x86_64 bootblock supportPatrick Rudolph
Add support for x86_64 bootblock on qemu. Introduce a new approach to long mode support. The previous patch set generated page tables at runtime and placed them in heap. The new approach places the page tables in memory mapped ROM. Introduce a new tool called pgtblgen that creates x86 long mode compatible page tables and writes those to a file. The file is included into the CBFS and placed at a predefined offset. Add assembly code to load the page tables, based on a Kconfig symbol and enter long in bootblock. The code can be easily ported to real hardware bootblock. Tested on qemu q35.
