* "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...
