Thank you for your suggestion, then in the next version I will submit to 
rename directory npcm to nuvoton.

And rename this file nuvoton.yaml to nuvoton,ma35d1.yaml, and put in the 
nuvoton directory.

npcm focuses on the BMC field, and ma35 is the successor SoC of 
nuc970/nuc980,

which is mostly used in industrial control, consumer, network 
applications and other fields.

The two teams are located in different countries and regions, and there 
is little

communication and resource sharing with each other.
