Except for CONFIG_DEFAULT_DEVICE_TREE and CONFIG_DEFAULT_FDT_FILE, 1.2a and 1.3b versions use the same config.
Version 1.3b uses the following configuration: CONFIG_DEFAULT_DEVICE_TREE="jh7110-starfive-visionfive-2-v1.3b" CONFIG_DEFAULT_FDT_FILE="starfive/jh7110-starfive-visionfive-2-v1.3b.dtb"
Version 1.2a uses the following configuration: CONFIG_DEFAULT_DEVICE_TREE="jh7110-starfive-visionfive-2-v1.2a" CONFIG_DEFAULT_FDT_FILE="starfive/jh7110-starfive-visionfive-2-v1.2a.dtb"
Is it necessary to separate the configs for 1.2a and 1.3b as separate defconfig files?
It makes a difference for when ethernet support is added.
The difference between 1.2a and 1.3b versions is mainly in ethernet, so the definition of dts is separated. Defconfig file in addition to the differences mentioned above, the others are the same. Your suggestion is to define defconfig file separately, is that right?
Yes, a 1.2a board will need to use the 1.2a device tree to get a working ethernet, IIUC.
