At the moment isa-bus.c is compiled unconditionally for all targets. However, some targets have never used legacy ISA devices. Many more targets have at least some machine types without ISA.
These patches allow ISA bus to be disabled in the configuration, thus allowing cut down configurations for targets and machine types that don't have ISA. In addition to creating the CONFIG_ISA_BUS config option itself, this involves breaking some non-obvious dependencies on the ISA code.
