I'm not following you.  The lines are:

# ifdef machine_arch_type
#  undef machine_arch_type
#  define machine_arch_type     __machine_arch_type
# else
#  define machine_arch_type     MACH_TYPE_CSB337
# endif
# define machine_is_csb337()    (machine_arch_type == MACH_TYPE_CSB337)
# define machine_is_csb337()    (0)

... and similar for EK.  The csb337 config file sets CONFIG_MACH_CSB337,
and nothing else does.  Result:  on rm9200ek, that test becomes if(0),
while on csb337 it becomes if (X == X), where X == MACH_TYPE_CSB337.

See above.  There already *IS* such an #ifdef, but it's just not
cluttering up the guts of that driver.
