This is somewhat confusing and makes it more likely ton configure a driver that works nowhere. Split up the Kconfig option into separate ISA and PLATFORM drivers, with the ISA symbol explicitly connecting to the static probing in drivers/net/Space.c The two drivers are still mutually incompatible at compile time, which could be lifted by splitting them into multiple files, but in practice this will make no difference. The platform driver can now be enabled for compile-testing on non-ARM machines.

However, all of these only support a single device, and they completely ignore the command line settings from netdev_boot_setup_check, so there is really no point at all. Aside from sun3_82586, these already have a module_init function that can be used for built-in mode as well, simply by removing the #ifdef. Note that the 82596 driver was previously used on ISA as well, but that got dropped long ago.
