25 | * Lots of code copied from: | |
26 | * | |
27 | * m8xx_pcmcia.c - Linux PCMCIA socket driver for the mpc8xx series. | |
28 | * (C) 1999-2000 Magnus Damm <damm@bitsmart.com> | |
29 | * | |
30 | * "The ExCA standard specifies that socket controllers should provide | |
31 | * two IO and five memory windows per socket, which can be independently | |
32 | * configured and positioned in the host address space and mapped to | |
33 | * arbitrary segments of card address space. " - David A Hinds. 1999 | |
34 | * | |
35 | * This controller does _not_ meet the ExCA standard. | |
36 | * | |
37 | * m8xx pcmcia controller brief info: | |
38 | * + 8 windows (attrib, mem, i/o) | |
39 | * + up to two slots (SLOT_A and SLOT_B) | |
40 | * + inputpins, outputpins, event and mask registers. | |
41 | * - no offset register. sigh. | |
42 | * | |
43 | * Because of the lacking offset register we must map the whole card. | |
44 | * We assign each memory window PCMCIA_MEM_WIN_SIZE address space. | |
45 | * Make sure there is (PCMCIA_MEM_WIN_SIZE * PCMCIA_MEM_WIN_NO | |
46 | * * PCMCIA_SOCKETS_NO) bytes at PCMCIA_MEM_WIN_BASE. | |
47 | * The i/o windows are dynamically allocated at PCMCIA_IO_WIN_BASE. | |
48 | * They are maximum 64KByte each... | |
