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.

2019-02-13riscv: Add initial support for 32bit boardsPhilipp Hug
* Adding separate targets for 32bit and 64bit qemu * Using the riscv64 toolchain for 32bit builds requires setting -m elf32lriscv * rv32/rv64 is currently configured with ARCH_RISCV_RV32/RV64 and not per stage. This should probably be changed later. TEST=Boots to "Payload not loaded." on 32bit qemu using the following commands: util/riscv/make-spike-elf.sh build/coreboot.rom build/coreboot.elf qemu-system-riscv32 -M virt -m 1024M -nographic -kernel build/coreboot.elf Change-Id: I35e59b459d1770df10b51fe9e77dcc474d7c75a0 Signed-off-by: Philipp Hug <philipp@hug.cx> Reviewed-on: https://review.coreboot.org/c/31253 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: ron minnich <rminnich@gmail.com>
2018-12-07riscv: fix non-SMP supportPhilipp Hug
Use CONFIG_CPU_MAX which defaults to 1 instead of CONFIG_RISCV_HART_NUM. The default value of CONFIG_RISCV_HART_NUM was 0 and cause a jump to address 0. Add a die() call to fail gracefully.
