2026-05-09platform: Remove kendryte/k210 platformAnup Patel
The kendryte/k210 platform does not have MMU support in S-mode hence only NOMMU kernel which runs in M-mode can be used on this platform. As of now, there is no clear use-case of supporting OpenSBI for kendryte/k210 platform.

2025-11-05platform: ariane: Move ariane platform from fpga to genericManuel Hernández Méndez
The Ariane framework has a generic PMU that is not used by OpenSBI. Due to OpenSBI’s build system we cannot directly reuse the generic platform functions, so move the Ariane platform to generic. Also due to the generic platform is where new features are added.

2025-03-23scripts: Fix firmware binaries compilation in create-binary-archive.shAnup Patel
Currently, the generic libsbi.a is compiled in create-binary-archive.sh before platform specific firmwares so a libsbi.a without any SBI extension gets linked to the platform specific firmwares. To address this, remove the temporary build directory in create-binary-archive.sh before using it. Signed-off-by: Anup Patel <[email protected]>
2024-12-15scripts/carray: change to using single awk invocation to generate .cBen Dooks
The shell script makes multiple call-outs to awk to get information from the configuration file. It would be easier to just write the whole thing in one .awk script and have the makefile altered to call that instead. There should be no functional difference other than the script type and has been tested with PLATFORM=generic build. This should be both quicker and easier to understand.

2024-11-28scripts/carray.sh: Allow referencing a struct memberSamuel Holland
It can be useful to embed the objects referenced by a carray inside another struct. To avoid type punning, the generated carray code must use the correct type for the enclosing struct and member access to compute the desired object address.

2024-11-28treewide: Make carray arrays const and NULL-terminatedSamuel Holland
This allows the compiler to generate significantly better code, because it does not have to maintain either the loop counter or loop limit. Plus there are half as many symbols to relocate. This also simplifies passing carray arrays to helper functions. Signed-off-by: Samuel Holland <[email protected]> Reviewed-by: Anup Patel <[email protected]>

Not all systems have bash at a fixed location like /bin/bash. FreeBSD, for example, would typically have it at /usr/local/bin/bash. When building OpenSBI on freebsd system, the build breaks.

2022-08-08Makefile: Compile lib/utils sources separately for each platformAnup Patel
Currently, if same build directory is used to compile two different platforms then lib/utils objects are shared for these platforms. We will be having platform specific configs to enable/disable drivers in lib/utils and select compile time options for lib/utils sources. This means lib/utils sources will now be compiled in a platform specific way. To tackle above, we update top-level Makefile as follows: 1) Don't create libsbiutils.a anymore because this can't be shared between platforms. 2) Compile lib/utils sources separately for each platform. 3) Add comments showing which make rules are for lib/sbi, lib/utils, firmware, and platform sources.

2022-05-13Makefile: Add support for generating C array at compile timeAnup Patel
Generating C array at compile time based on details provided by objects.mk is a very useful feature which will help us compile only a subset of drivers or modules. We add a bash script (carray.sh) which takes array details and object/variable list from command-line to generate a C source containing array of object/variable pointers. We also extend top-level makefile to use carray.sh whenever specified through objects.mk. Signed-off-by: Anup Patel <[email protected]> Reviewed-by: Atish Patra <[email protected]>

2020-06-05Makefile: Add mechanism for platforms to have multiple builtin DTBsAnup Patel
Currently, we can only include one DTB as builtin for a platform using FDT_PAYLOAD_DTB make variable in platform config.mk. This patch adds new mechanism using which we can convert any DTS file to C source and futher compile-n-link it with libplatsbi.a. The generated C source will have the DTB contents as an array "const char <varprefix>_start[]" where <varprefix> is specified in platform objects.mk makefile. Example1 -------- If we have built-in k210.dts and desired <varprefix> is "dt_k210" then specify following in platform objects.mk: platform-objs-y += k210.o platform-varprefix-k210.o = dt_k210 Example2 -------- If we have built-in abc/k210.dts and desired <varprefix> is "dt_abc_k210" then specify following in platform objects.mk: platform-objs-y += abc/k210.o platform-varprefix-abc-k210.o = dt_abc_k210 Signed-off-by: Anup Patel <[email protected]> Reviewed-by: Atish Patra <[email protected]>
