    base: isa: Remove X86_32 dependency · b3c1be1b
    William Breathitt Gray authored
    Many motherboards utilize a LPC to ISA bridge in order to decode
    ISA-style port-mapped I/O addresses. This is particularly true for
    embedded motherboards supporting the PC/104 bus (a bus specification
    derived from ISA).
    These motherboards are now commonly running 64-bit x86 processors. The
    X86_32 dependency should be removed from the ISA bus configuration
    option in order to support these newer motherboards.
    A new config option, CONFIG_ISA_BUS, is introduced to allow for the
    compilation of the ISA bus driver independent of the CONFIG_ISA option.
    Devices which communicate via ISA-compatible buses can now be supported
    independent of the dependencies of the CONFIG_ISA option.
