README.md: Improve project copyright information

2023-06-14T05:56:06Z

Over-time a lot of organizations and individuals have contributed to the OpenSBI project so let us add copyright RISC-V International to respect the contributions from all RISC-V members. Signed-off-by: Anup Patel Reviewed-by: Andrew Jones

docs: Add OpenSBI logo and use it in the top-level README.md

2023-06-14T05:56:04Z

We do have an official OpenSBI logo which was designed few months ago and was also approved by RISC-V International. Lets add this logo under docs and also use it in the top-level README.md Signed-off-by: Anup Patel Reviewed-by: Andrew Jones

make: Add a command line option for debugging OpenSBI

2023-03-01T03:53:17Z

Add a new make command line option "make DEBUG=1" to prevent compiler optimizations using -O2. Signed-off-by: Bin Meng Reviewed-by: Xiang W Reviewed-by: Anup Patel

docs: Update documentation for kconfig support

2022-08-08T04:04:31Z

We update all documentation files to: 1) Remove references to platform specific config.mk file since it is has been removed. 2) Add details about platform specific configs/defconfig and Kconfig files mandatory for each platform. 3) Add required packages in top-level README.md 4) Fix typo releated to object.mk in docs/platform/platform.md Signed-off-by: Anup Patel Reviewed-by: Andrew Jones Tested-by: Andrew Jones Acked-by: Atish Patra Tested-by: Atish Patra

Makefile: Add build time and compiler info string

2021-10-20T09:40:52Z

When we are doing opensbi development, we want to know the build time and compiler info for debug purpose. To enable this message, please add "BUILD_INFO=y", like: ``` make BUILD_INFO=y ``` NOTE: Using `BUILD_INFO=y` without specifying SOURCE_DATE_EPOCH will violate "reproducible builds". So it's ONLY for development and debug purpose, and should NOT be used in a product which follows "reproducible builds". Signed-off-by: Wei Fu Reviewed-by: Anup Patel Reviewed-by: Alistair Francis

README: Update toolchain information

2021-07-17T13:02:20Z

Recent FW_PIC=y changes actually require toolchains with PIE support and it is on by default. Existing doc uses a GNU bare-metal toolchain as examples but it does not support PIE. Replace references of bare-metal toolchain prefix with Linux toolchain prefix everywhere in documentation. Also indicate that "riscv64-unknown-freebsd-" as an alternative to "riscv64-linux-" GNU toolchain. Signed-off-by: Bin Meng Reviewed-by: Anup Patel

Makefile: Support building with Clang and LLVM binutils

2021-07-11T14:52:55Z

This is intended to mirror the Linux kernel. Building with CC=clang will use Clang as the compiler but default to using the existing binutils. Building with LLVM=1 will default to using Clang and LLVM binutils. Whilst GCC will accept the -N linker option and forward it on to the linker, Clang will not, and so in order to support both compilers we must use -Wl, to forward it to the linker as is required for most other linker options. Note that there is currently a bug when using Clang as the compiler and riscv64-linux-gnu-ld as the linker for FW_PIC=y. At first glance this appears to be a bug in GNU binutils, but this could also be Clang or OpenSBI at fault in some subtle way. Thus, for now, advise that this combination be avoided.

docs: Add initial documentation for domain support

2020-10-21T06:59:36Z

We add initial documentation for OpenSBI domain support to help RISC-V platform vendors achieve system-level partitioning. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

README.md: fix markdown link formatting

2020-07-04T04:28:03Z

Consistently use reference-style markdown links in the README. This won't show the URL next to the linked text for the [Github] and [U-Boot] links and link the text "Bootlin toolchain repository" instead of showing it verbatim with the URL next to it.

docs: Use doxygen config to mark the main page

2020-06-08T11:32:41Z

The doxygen config option "USE_MDFILE_AS_MAINPAGE" can be used to set the main page in doxygen generated pdf. This allows us to remove the "#mainpage" from the README file which markdown doesn't parse. Signed-off-by: Atish Patra Reviewed-by: Anup Patel
