[PATCH 02/13] powerpc/5200: LocalPlus driver: use SCLPC register structure

[Wolfgang Denk]

Dear Grant,

May I ask _why_ you consider this bad practice?

Is a structure not the most natural way to encode the specifics of a
hardware interface (address offet, bus width, etc.) in C?

What do you recommend instead?  Using lists of register offsets
(without any type information) as for example ARM is doing?

Could you please explain this reason?


I'm trying to understand if this is a MPC52xx specific reasoning, or
if you apply this to all of PowerPC, or generally to all kernel code?

And: is this just your personal preferences, or generally agreed on?

Thanks in advance, and sorry for asking stupid questions, but your
reply surprised me...

Best regards,

Wolfgang Denk
