+ * Lots of code copied from:

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