Dear Arnd and Krzysztof,

Thank you for your suggestion, it really helped me. We are also considering
whether to use ARCH_MA35. As NPCM and MA35 are designed for different
application areas, it is unlikely that they would be used simultaneously.
Therefore, it would be more reasonable to separate them into ARCH_NPCM and
ARCH_MA35. In the next version, v10, we will change all instances of
ARCH_NUVOTON in this patchset to ARCH_MA35 and keep shared directory 
changed.
