- * Lots of code copied from:
- *
- * m8xx_pcmcia.c - Linux PCMCIA socket driver for the mpc8xx series.
- * (C) 1999-2000 Magnus Damm <damm at 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...
