13 * "The ExCA standard specifies that socket controllers should provide
14 * two IO and five memory windows per socket, which can be independently
15 * configured and positioned in the host address space and mapped to
16 * arbitrary segments of card address space. " - David A Hinds. 1999
17 *
18 * This controller does _not_ meet the ExCA standard.
19 *
20 * m8xx pcmcia controller brief info:
21 * + 8 windows (attrib, mem, i/o)
22 * + up to two slots (SLOT_A and SLOT_B)
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.
28 * Make sure there is (PCMCIA_MEM_WIN_SIZE * PCMCIA_MEM_WIN_NO
29 * * PCMCIA_SOCKETS_NO) bytes at PCMCIA_MEM_WIN_BASE.
30 * The i/o windows are dynamically allocated at PCMCIA_IO_WIN_BASE.
31 * They are maximum 64KByte each...
