Then having both is not valid. The strings should be in order of best
match to worst match where worst match is typically either older
implementations of IP blocks or generic'ish strings such as "ns16550"
for a UART.

Thanks.
I would like to explain it more clearly.
They are independent ones in implementations.
They are implemented based on the same nds32 ISA and architecture spec
with different configurations
like cache size, page size, cache type(VIPT/PIPT), pipeline stages...
Most of them are compatible.
They use the same toolchain to build vmlinux which can run on
different nds32 cores.

Du you have a name for the ISA spec that distinguishes it from other nds32
versions that are incompatible? If you do, this could be written like

compatible = "andestech,n13", "andestech,nds32v3.0";

to signify that a an 'n13' core implements the 'v3.0' ISA (will it
whatever you call the ISA in reality).

Thanks. I got you.
I will use a proper name(maybe 'nds32v3') of ISA in this compatible
string in the next version patch.
