[PATCH] drivers/isdn/hisax/Kconfig: Let HISAX_NETJET skip microblaze architecture

[PATCH] drivers/isdn/hisax/Kconfig: Let HISAX_NETJET skip microblaze architecture

[Chen Gang]

For HISAX_NETJET, HISAX_NETJET_U or related config needs !__BIG_ENDIAN,
so skip microblaze, just like skip all other architectures which have
no CONFIG_*_ENDIAN.

The related error (with allmodconfig under microblaze):

    CC [M]  drivers/isdn/hisax/nj_s.o
  drivers/isdn/hisax/nj_s.c: In function 'setup_netjet_s':
  drivers/isdn/hisax/nj_s.c:265:2: error: #error "not running on big endian machines now"
   #error "not running on big endian machines now"
    ^

Fine with me, however the list is getting long. 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?

Yes, that idea pops up once in a while.

BTW, these days little endian PPC is also supported by Linux...

OK, thanks, what all of you said sounds reasonable to me.

Hello Geert:

Could you help send the related patch for it?


Thanks.

If no additional response within 3 days, I shall continue to try to send
patch for it.

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.

Thanks.
