| ******************************************************************** |

| * 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... |
