    asm-generic: add legacy I/O header files · ae49e807
    Arnd Bergmann authored
    The dma.h, hw_irq.h, serial.h and timex.h files originally
    described PC-style i8237, i8259A, i8250, i8253 and i8255 chips
    as well as the VGA style text mode graphics.
    
    Modern architectures live happily without these specific
    interfaces, but a few definitions from these headers keep
    getting used in common code.
    
    The new generic headers are what most architectures use
    anyway nowadays, just implementing the minimal definitions.
