[RFC,PATCH] pcmcia/yenta: make bridge specific init code configurable
make the bridge specific initialization code config options depending on
CONFIG_EMBEDDED. config options for TI/EnE, Toshiba, Ricoh and O2Micro are
available. disabling all of the specific options cuts off more than halve
of yenta_socket.ko:
full (default):
text data bss dec hex filename
19674 2340 12 22026 560a drivers/pcmcia/yenta_socket.ko
minimal:
text data bss dec hex filename
8427 836 12 9275 243b drivers/pcmcia/yenta_socket.ko
[ i never said it's pretty...to much preprocessor crap in a .c...but still ]
