after running CI yesterday, it failed in many cases: https://travis-ci.org/github/rickchen36/u-boot-riscv/builds/678023975 and I trace at least two cases belong to your patch 49.59 https://travis-ci.org/github/rickchen36/u-boot-riscv/jobs/678024035 arning, treated as error: /home/travis/build/rickchen36/u-boot-riscv/doc/board/sipeed/maix.rst:173:Error in "code-block" directive: 1 argument(s) required, 0 supplied. .. code-block:: &sysclk { assigned-clocks = <&sysclk K210_CLK_PLL0>; assigned-clock-rates = <800000000>; }; doc/Makefile:69: recipe for target 'htmldocs' failed make[1]: *** [htmldocs] Error 1 49.66 https://travis-ci.org/github/rickchen36/u-boot-riscv/jobs/678024042 ./tools/patman/patman --test && ./tools/buildman/buildman -t && ./tools/dtoc/dtoc -t && make testconfig; fi; fi cp: cannot create regular file '/home/travis/build/rickchen36/sandbox/': Not a directory cp: cannot create regular file '/home/travis/build/rickchen36/sandbox/': Not a directory WARNING: no status info for 'sipeed_maix_bitm' WARNING: no maintainers for 'sipeed_maix_bitm' So I will drop your patchs and run CI again today. And hope you can fix them in next version and pass CI verification. Thanks, Rick
