This doesn't give us any insight as to what the errors were. Can you provide more detail?

What build errors did you see?

Can you unpack what were you trying to achieve by copying socsec-sign.bbclass?

Have you tried building without applying patches to u-boot and linux-aspeed? It's not clear whether its your own patches that are breaking the build or if something else is afoot.
