It would be better if we could depend on a functional symbol rather than a negated list of architectures. Would it make sense to have CONFIG_CPU_LITTLE_ENDIAN defined on all little-endian architectures, so that driver can depend on that if needed? Alternatively, it might make more sense to list the architectures where these drivers are actually used in practice. I guess that's X86, maybe ARM and IA64, and that's all?

Hello Geert: Could you help send the related patch for it? Thanks.

Excuse me, I need additional thinking of for it, so I plan to send patch for discussing and review within next week end (2014-08-17). And welcome any members' ideas, suggestions and completions.
