help for kernel initcall section (init.h)

[Pintu Agarwal]

Hi,
 
I need some help in modifying initcall section in init.h.
 
That is :
 
#define __define_initcall(level,fn,id) \
 static initcall_t __initcall_##fn##id __used \
 __attribute__((__section__(".initcall" level ".init"))) = fn
 
I have to create two different kinds (and later more) of init section and use one of them based on some condition.
For example, I have one init section for normal mode and one init section for charger mode.
During charger mode, I do not have to execute all the initcall so a charger.initcall is create with lesser init function.
The charger initcall section is as follows:
#define __define_charger_initcall(level,fn,id) \
 static initcall_t __charger_initcall_##fn##id __used \
 __attribute__((__section__(".charger.initcall" level ".init"))) = fn
 
 
Now the problem is that during compile time both of them needs to be polulated based on CHARGER_MODE is enabled or disabled.
How can this decision be taken during compile time under the macro "__define_initcall" ??
 
Something like :
 
#define __define_initcall(level,fn,id)     \
                                                       static initcall_t __initcall_##fn##id __used \
                                                       __attribute__((__section__(".initcall" level ".init"))) = fn  \
                                                       #if defined(CHARGER_MODE)  \
                                                       static initcall_t __charger_initcall_##fn##id __used  \
                                                       __attribute__((__section__(".charger.initcall" level ".init"))) = fn   \
                                                       #endif
 
Right now this cannot be done, as macro cannot exists inside a macro statement.
 
If any body have any alternative or better idea of doing this please help.
 
In gernal, how can I take decision during compile time itself and decide which initcall to be used instead of calling all of them.
 
 
 
Thanks, Regards.
