From: Simon Glass <sjg@chromium.org> This series completes the implementation of a basic U-Boot library: - ensure that no output is written during init - provide a static library to match the existing shared library - add test programs for both, to ensure they continue to build correctly - provide documentation to describe how to use the libraries This is still very early in the implementation, but this series provides enough for some initial experimentation. Simon Glass (15): sandbox: Add a function to read a line from a file ulib: Disable environment setup ulib: Disable console messages ulib: Disable network setup ulib: Disable the main loop ulib: Move struct bd_info into its own header ulib: sandbox: Move the linker-script name into config.mk ulib: Add static-library build support ulib: Provide an init function for sandbox ulib: Provide a generic init function ulib: Provide a test program for the static library ulib: Drop unnecessary pieces in test/ulib/Makefile ulib: Provide a bit more info in the library-test program ulib: Allow building of the libraries to be disabled doc: Add ulib documentation for shared and static libraries Makefile | 38 +++- arch/sandbox/config.mk | 4 + arch/sandbox/cpu/os.c | 32 +++ arch/sandbox/cpu/start.c | 30 ++- arch/sandbox/cpu/ulib-test-static.lds | 19 ++ arch/sandbox/include/asm/u-boot-sandbox.h | 9 + common/board_r.c | 14 ++ common/console.c | 2 +- doc/develop/index.rst | 1 + doc/develop/ulib.rst | 253 ++++++++++++++++++++++ include/asm-generic/u-boot.h | 52 +---- include/bd.h | 70 ++++++ include/init.h | 4 + include/os.h | 14 ++ include/u-boot-lib.h | 34 +++ lib/Makefile | 2 + lib/ulib.c | 36 +++ test/ulib/Makefile | 7 - test/ulib/ulib_test.c | 53 +++-- 19 files changed, 593 insertions(+), 81 deletions(-) create mode 100644 arch/sandbox/cpu/ulib-test-static.lds create mode 100644 doc/develop/ulib.rst create mode 100644 include/bd.h create mode 100644 include/u-boot-lib.h create mode 100644 lib/ulib.c -- 2.43.0 base-commit: d1e8f71cb5e8648328b8043b8f1a3ea780b4e50d branch: ulid
