2024-03-15treewide: Move stdlib.h to commonlibMaximilian Brune
This patch moves commonlib/stdlib.h -> commonlib/bsd/stdlib.h, since all code is BSD licensed anyway. It also moves some code from libpayloads stdlib.h to commonlib/bsd/stdlib.h so that it can be shared with coreboot. This is useful for a subsequent commit that adds devicetree.c into commonlib. Also we don't support DMA on arm platforms in coreboot (only libpayload) therefore `dma_malloc()` has been removed and `dma_coherent()` has been moved to architecture specific functions. Any architecture that tries to use `dma_coherent()` now will get a compile time error. In order to not break current platforms like mb/google/herobrine which make use of the commonlib/storage/sdhci.c controller which in turn uses `dma_coherent` a stub has been added to arch/arm64/dma.c.

2024-03-14arch/riscv: support physical memory protection (PMP) registersRonald G Minnich
PMP (Physical Memory Protection) is a feature of the RISC-V Privileged Architecture spec, that allows defining region(s) of the address space to be protected in a variety of ways: ranges for M mode can be protected against access from lower privilege levels, and M mode can be locked out of accessig to memory reserved for lower privilege levels. Limits on Read, Write, and Execute are allowed. In coreboot, we protect against Write and Execute of PMP code from lower levels, but allow Reading, so as to ease data structure access. PMP is not a security boundary, it is an accident prevention device. PMP is used here to protect persistent ramstage code that is used to support SBI, e.g. printk and some data structures. It also protects the SBI stacks. Note that there is one stack per hart. There are 512- and 1024-hart SoC's being built today, so the stack should be kept small. PMP is not a general purpose protection mechanism and it is easy to get around it. For example, S mode can stage a DMA that overwrites all the M mode code. PMP is, rather, a way to avoid simple accidents. It is understood that PMP depends on proper OS behavior to implement true SBI security (personal conversation with a RISC-V architect). Think of PMP as "Protection Minus Protection". PMP is also a very limited resource, as defined in the architecture. This language is instructive: "PMP entries are described by an 8-bit configuration register and one XLEN-bit address register. Some PMP settings additionally use the address register associated with the preceding PMP entry. Up to 16 PMP entries are supported. If any PMP entries are implemented, then all PMP CSRs must be implemented, but all PMP CSR fields are WARL and may be hardwired to zero. PMP CSRs are only accessible to M-mode." In other words if you implement PMP even a little, you have to impelement it all; but you can implement it in part by simply returning 0 for a pmpcfg. Also, PMP address registers (pmpaddr) don't have to implement all the bits. On a SiFive FU740, for example, PMP only implements bits 33:0, i.e. a 34 bit address. PMPs are just packed with all kinds of special cases. There are no requirements that you read back what you wrote to the pmpaddr registers. The earlier PMP code would die if the read did not match the write, but, since pmpaddr are WARL, that was not correct. An SoC can just decide it only does 4096-byte granularity, on TOR PMP types, and that is your problem if you wanted finer granulatiry. SoC's don't have to implement all the high order bits either. And, to reiterate, there is no requirement about which of the pmpcfg are implemented. Implementing just pmpcfg15 is allowed. The coreboot SBI code was written before PMP existed. In order for coreboot SBI code to work, this patch is necessary. With this change, a simple S-mode payload that calls SBI putchar works: 1: li a7, 1 li a0, 48 ecall j 1b Without this change, it will not work. Getting this to build on RV32 required changes to the API, as it was incorrect. In RV32, PMP entries are 34 bits. Hence, the setup_pmp needed to accept u64. So, uinptr_t can not be used, as on 32 bits they are only 32 bit numbers. The internal API uses uintptr_t, but the exported API uses u64, so external code does not have to think about right shifts on base and size. Errors are detected: an error in base and size will result in a BIOS_EMERG print, but not a panic. Boots not bricks if possible. There are small changes to the internal API to reduce stack pressure: there's no need to have two pmpcfg_t on the stack when one will do. TEST: Linux now boots partly on the SiFive unmatched. There are changes in flight on the coreboot SBI that will allow Linux to boot further, but they are out of scope for this patch. Currently, clk_ignore_unused is required, this requires a separate patch.

2022-07-14commonlib: Substitude macro "__unused" in compiler.hBill XIE
Since there are many identifiers whose name contain "__unused" in headers of musl libc, introducing a macro which expands "__unused" to the source of a util may have disastrous effect during its compiling under a musl-based platform. However, it is hard to detect musl at build time as musl is notorious for having explicitly been refusing to add a macro like "__MUSL__" to announce its own presence. Using __always_unused and __maybe_unused for everything may be a good idea. This is how it works in the Linux kernel, so that would at least make us match some other standard rather than doing our own thing (especially since the other compiler.h shorthand macros are also inspired by Linux).

It seems that GCC's LTO doesn't like the way we implement DECLARE_OPTIONAL_REGION(). This patch changes it so that rather than having a normal DECLARE_REGION() in <symbols.h> and then an extra DECLARE_OPTIONAL_REGION() in the C file using it, you just say DECLARE_OPTIONAL_REGION() directly in <symbols.h> (in place and instead of the usual DECLARE_REGION()).

2020-06-13treewide: Add Kconfig variable MEMLAYOUT_LD_FILEFurquan Shaikh
This change defines a Kconfig variable MEMLAYOUT_LD_FILE which allows SoC/mainboard to provide a linker file for the platform. x86 already provides a default memlayout.ld under src/arch/x86. With this new Kconfig variable, it is possible for the SoC/mainboard code for x86 to provide a custom linker file as well. Makefile.inc is updated for all architectures to use this new Kconfig variable instead of assuming memlayout.ld files under a certain path. All non-x86 boards used memlayout.ld under mainboard directory. However, a lot of these boards were simply including the memlayout from SoC. So, this change also updates these mainboards and SoCs to define the Kconfig as required. BUG=b:155322763 TEST=Verified that abuild with --timeless option results in the same coreboot.rom image for all boards.

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.

2019-07-12arch, 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.
