23 | * + inputpins, outputpins, event and mask registers. | ||
24 | * - no offset register. sigh. | ||
25 | * | ||
26 | * Because of the lacking offset register we must map the whole card. | ||
27 | * We assign each memory window PCMCIA_MEM_WIN_SIZE address space. | ||

29 | * * PCMCIA_SOCKETS_NO) bytes at PCMCIA_MEM_WIN_BASE. | ||
30 | * The i/o windows are dynamically allocated at PCMCIA_IO_WIN_BASE. | ||
