Given the checks for __NDS32_EB__, NDS32 can be either big or little endian,
so you should have (excatly one of) CPU_BIG_ENDIAN or CPU_LITTLE_ENDIAN set.

Thanks.
I will check if we need this config or not and update in the next version patch.

I think we have one architecture in the kernel that determines endianess from
the way that the toolchain is built. What all the others do it to have a Kconfig
option, at least CONFIG_CPU_BIG_ENDIAN that is used to pass -mbig-endian
or -mlittle-endian to the compiler. You should do it that way so you can use
any toolchain with any kernel configuration.
