Could you please stop full-quoting? Please see

Yes, except that the "echo" line should not be needed either, as
mkconfig would to that automatically for you.

That would be CONFIG_MPC8536DS_NAND etc., but except of that that's
whaty I mean. [Eventually it might make sense to ise a common prefix
for Maefile generated symbols, like CONFIG_MK_ or so.]

Thanks.
