27 * Lots of code copied from:
28 *
29 * m8xx_pcmcia.c - Linux PCMCIA socket driver for the mpc8xx series.
30 * (C) 1999-2000 Magnus Damm <damm@bitsmart.com>
31 *
32 * "The ExCA standard specifies that socket controllers should provide
33 * two IO and five memory windows per socket, which can be independently
34 * configured and positioned in the host address space and mapped to
35 * arbitrary segments of card address space. " - David A Hinds. 1999
36 *
37 * This controller does _not_ meet the ExCA standard.
38 *
39 * m8xx pcmcia controller brief info:
40 * + 8 windows (attrib, mem, i/o)
41 * + up to two slots (SLOT_A and SLOT_B)
42 * + inputpins, outputpins, event and mask registers.
43 * - no offset register. sigh.
44 *
45 * Because of the lacking offset register we must map the whole card.
46 * We assign each memory window PCMCIA_MEM_WIN_SIZE address space.
47 * Make sure there is (PCMCIA_MEM_WIN_SIZE * PCMCIA_MEM_WIN_NO
48 * * PCMCIA_SOCKETS_NO) bytes at PCMCIA_MEM_WIN_BASE.
49 * The i/o windows are dynamically allocated at PCMCIA_IO_WIN_BASE.
50 * They are maximum 64KByte each...
