/*
 * The DMA channel used by the floppy controller cannot access data at
 * addresses >= 16MB
 *
 * Went back to the 1MB limit, as some people had problems with the floppy
 * driver otherwise. It doesn't matter much for performance anyway, as most
 * floppy accesses go through the track buffer.
 *
 * On MIPSes using vdma, this actually means that *all* transfers go thru
 * the * track buffer since 0x1000000 is always smaller than KSEG0/1.
 * Actually this needs to be a bit more complicated since the so much different
 * hardware available with MIPS CPUs ...
