Not having a defconfig doesn't mean something is not supported. There are tons of features in Buildroot that are not enabled by defconfig, and still we do support them. > Change commit log, like this: > > Subject: Change DSP to VDSP for -mcpu > > DSP extention is no longer used for C-SKY gcc and there is no > defconfig use "e" extension > in buildroot. Again, the defconfig aspect is irrelevant. Only the fact the extension is no longer used for C-SKY is relevant. > VDSP is C-SKY enhanced extension instruction set for SIMD, AI and DSP > operation. It could be supported by abiv2 (ck807, ck810, ck860). > > Is that OK? Yes, with the change above. Thanks!
