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.

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.

2019-09-14arm64: Uprev Arm TF and adjust to BL31 parameter changesJulius Werner
This patch uprevs the Arm Trusted Firmware submodule to the new upstream master (commit 42cdeb930). Arm Trusted Firmware unified a bunch of stuff related to BL31 handoff parameters across platforms which involved changing a few names around. This patch syncs coreboot back up with that. They also made header changes that now allow us to directly include all the headers we need (in a safer and cleaner way than before), so we can get rid of some structure definitions that were duplicated. Since the version of entry point info parameters we have been using has been deprecated in Trusted Firmware, this patch switches to the new version 2 parameter format. NOTE: This may or may not stop Cavium from booting with the current pinned Trusted Firmware blob. Cavium maintainers are still evaluating whether to fix that later or drop the platform entirely. Tested on GOOGLE_KEVIN (rk3399).

Previously, CBMEM console detected on-the-fly that CAR migration had happened and relocated cbmem_console_p accoringlin with car_sync_var().

2019-08-20src: Remove variable length arraysJacob Garber
Variable length arrays were a feature added in C99 that allows the length of an array to be determined at runtime. Eg. int sum(size_t n) { int arr[n]; ... } This adds a small amount of runtime overhead, but is also very dangerous, since it allows use of an unlimited amount of stack memory, potentially leading to stack overflow. This is only worsened in coreboot, which often has very little stack space to begin with. Citing concerns like this, all instances of VLA's were recently removed from the Linux kernel. In the immortal words of Linus Torvalds [0], AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and much _slower_ code (and more fragile code), than just using a fixed key size would have done. [...] Anyway, some of these are definitely easy to just fix, and using VLA's is actively bad not just for security worries, but simply because VLA's are a really horribly bad idea in general in the kernel. This patch follows suit and zaps all VLA's in coreboot. Some of the existing VLA's are accidental ones, and all but one can be replaced with small fixed-size buffers. The single tricky exception is in the SPI controller interface, which will require a rewrite of old drivers to remove [1].

smbios.h had already declared smbios_mainboard_enclosure_type so this change defines it. It can be overridden in a mainboard so the enclosure type can be set at runtime. We have a mainboard that will be used in different enclosures and we are planning on using a single BIOS image for all of the enclosures so it will need to be set dynamically based on sku. BUG=b:138745917 TEST=Built arcada firmware and verified via dmidecode that enclosure type is correctly set to "Convertible", then temporarily added a smbios_mainboard_enclosure_type to arcadas board file returning 0x20 and verified with dmidecode that the enclosure type is "Detachable" Change-Id: Iba6e582640989f5cb7e6613813e7b033760a977c Signed-off-by: Mathew King <mathewk@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/34646 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Martin Roth <martinroth@google.com>

Call OpenSBI in M-Mode and use it to set up SBI and to lockdown the platform. It will also jump to the specified payload when done. This behaviour is similar to BL31 on aarch31. The payload is 41KiB in size on qemu. Tested on qemu-riscv: Required to boot a kernel as OpenSBI's instruction emulation feature is required on that virtual machine. Tested on SiFive/unleashed: The earlycon is working. No console after regular serial driver should take over, which might be related to kernel config.

2019-07-12arch, include, soc: Use common stdint.hJacob Garber
There are only minimal differences between the architecture specific stdint.h implementations, so let's tidy them up and merge them together into a single file. In particular, - Use 'unsigned long' for uintptr_t. This was already the case for x86 and riscv, while arm and mips used 'unsigned int', and arm64 and ppc64 used 'unsigned long long'. This change allows using a single integer type for uintptr_t across all architectures, and brings it into consistency with the rest of the code base, which generally uses 'unsigned long' for memory addresses anyway. This change required fixing several assumptions about integer types in the arm code. - Use _Bool as the boolean type. This is a specialized boolean type that was introduced in C99, and is preferrable over hacking booleans using integers. romcc sadly does not support _Bool, so for that we stick with the old uint8_t. - Drop the least and fast integer types. They aren't used anywhere in the code base and are an unnecessary maintenance burden. Using the standard fixed width types is essentially always better anyway. - Drop the UINT64_C() macro. It also isn't used anywhere and doesn't provide anything that a (uint64_t) cast doesn't. - Implement the rest of the MIN and MAX numerical limits. - Use static assertions to check that the integer widths are correct.
