Tuple and base-address question

[Matthias Wenzel]

Hi,

as a pcmcia-newbie I try to write a driver for a DECT-basestation.
It is based on an ISA-bus-design, and interfaced to PCMCIA through a
National Semiconductor PCM16C010 [0].

So far the driver only dumps what is in the tuples. Following tuples are
used:
         *  0x01 - CISTPL_DEVICE
         *  0x14 - CISTPL_NO_LINK
         *  0x15 - CISTPL_VERS_1
         *  0x1a - CISTPL_CONFIG
         *  0x1b - CISTPL_CFTABLE_ENTRY
         *  0x21 - CISTPL_FUNCID

Tuple contents, see [1]
I am trying to read more tuples with pcmcia_get_next_tuple() but
seemingly there's only one tuple for each entry, and I believe I dump
everything(?).

How do I derive a memory baseaddress from the values in [1]. Does
cftable_entry[0].mem.win[*] make any sense? Two areas of 0x1000 _both_
starting at 0x0000... but the datasheet [0] has two areas 0x0000-0x0800
and 0x1000-0x1060.

How would I calculate a 32-(or 64-)bit address for accessing that mem?
Or should I plainly use config.base (0x1020) as 32 bit base address
(0x00001020)?

thanks for any help,

Matthias
