In the header file arch/csky/abiv2/inc/abi/fpu.h, lines 30-64 refer to a series of configuration options starting with "OPEN_FPU" for conditional compilation, but these configuration options are not defined in any kconfig files, which means the "#ifdef CONFIG_OPEN_FPU_xxx" condition contains dead code.
Do these configuration options need to be retained and added later? Or can we simply drop the dead code? Best regards, Yanjie Ren Ying Sun
