/* $NetBSD: pcmcia_cis.c,v 1.17 2000/02/10 09:01:52 chopps Exp $ */
Moderately hacked pccard code from newconfig. It is somewhat in incomplete and likely has problem. The code was originally pcmcia, but I renamed it to pccard and made it compile on FreeBSD -current. I converted SIMPLEQ to STAILQ as well as a few sc->dev.xname -> device_printf changes. This is a green port of fairly mature code. I derived this work from the FreeBSD newconfig project (http://www.jp.freebsd.org/newconfig). Any problems with it are likely introduced by me. Obtained from: newconfig project

checkpoint latest pccard/pcic hacking: o Eliminate cross calls between the devices. Instead move to using the newbus messaging system. Added three new card calls: attach_card, detach_card, get_type. o Eliminate interrupt routine in pccard we never use. o Move from deactivate to detach for removing cards. o Start mapping CIS memory, but it is broken and causes panics. At least it is closer to working than before. o Eliminate struct device everywhere. It was bogus. o Initialize softc for pccard device so we have valid pointers to ourselves. o Implement routine to find the pcic ivar for a child device of the pccard so we can use it to talk to the pcic hardware. o Lots of minor tiding up. This version now panics when we try to read the CIS. The next batch of work to make this work is what was outlined in my posting to mobile about resource allocation and such.

When debugging CIS, only print 10 CISTPL_NULLs. Chances are good they are all bogus, and the cards that don't decode things quite right often have hundreds of them. This will fix starvation of small dmesg buffers and allow better debugging to happen. I thought about adding an override, but there is such a thing as too many knobs. :-)

Improve reading of CIS cards: (1) Align to 64k for the CIS. Some cards don't like it when we aren't aligned to a 64k boundary. I can't find anything in the standard that requires this, but I have 1/2 dozen cards that won't work at all unless I enable this. (2) Sleep 1s before scanning the CIS. This may be a nop, but has little harm. (3) The CIS can be up to 4k in some weird, odd-ball edge cases. Since we have limiters for when that's not the case, it does no harm to increase it to 4k. #1 was submitted, in a different form, by Carlos Velasco.

Thomas Wintergerst reports that when this tsleep went away, certain cards stopped working. Specifically the AVM B1 PCMCIA Card no longer detected. Its CIS chain read back as all FF's. Putting the delay back solves those problems. I've opted to put in a much shorter delay because as far as I can tell, no delay is really needed here. We'll see how well this works in practice.

OK. Next step: we read in CIS. I've done this by having requests to allocate memory propigate up the tree. We'll see how well this works and reevaluate if it isn't working well. Also initialize ptr in the tuple. As well as minor reorg of memory allocation. Likely need to do similar things for I/O when the time comes.

Put a band-aide(tm) on the CIS panic problem. This is a similar fix to what is in NetBSD. I have a few cards that tickles this bug, and this just keeps us from panicing. It doesn't actually fix the problem (that will happen once I figure out why some cards hate the address their CIS is mapped to high memory).

Improve support of MFC cards (Multi-function cards). This commit allows us to properly parse cards with attribute memory based CIS that before wouldn't parse correctly, sometimes with a panic. This allows me to get my 3C562 modem/ethernet card to fail to attach due to problems in the ep and sio drivers rather than due to problems in the CIS parsing code :-). We weren't setting the address to jump to for the function entries. This caused us to only work when the addional entries were after the first ones. On the 3C562/3C563 card this was not the case. We were also mapping Attribute memory when common memory was asked for in the target of the LONGLINK_{A,C} or LONGLINK_MFC. My IBM Home And Away Modem/LAN card still fails for reasons unknown.

Add a much-requested feature: The ability for pccard attachments to scan the CIS for interesting tuples. 95% of what can be obtained from the CIS is harvested by the pccard layer and presented to the user in standard function calls. However, there are special needs at times where the standard stuff doesn't suffice. This is for those special cases. CARD_SCAN_CIS(device_get_parent(dev), function, argp) scans the CIS of the card, passing each tuple to function with the tuple and argp as its arguments. Returning 0 continues the scan, while returning 1 terminates the scan. The value of the last invocation of function is returned from this function. int (*pccard_scan_t)(struct pccard_tuple *tuple, void *argp) function called for each tuple. Elements of the CIS tuple can be read with pccard_tuple_read_{1,2,3,4,n}(). You are reading the actual tuple memory each time, in case your card has registers in the CIS. # I suppose these things should be documented in pccard(4) or something like # that. # I plan on unifying cardbus CIS support in a similar way.

Upon relection, we shouldn't allow the tuple structs to be modified by the functor, so make it a const pointer, and chase down the resulting const-poisoning. Approved by: re (scottl)

memspace is set to some value by masking off bits. When these bits are equal to PCCARD_TPCE_FS_MEMSPACE_NONE, memspace will be zero, so testing for this case inside of the if statement results in dead code. We'd fail to set a value to zero that's already zero (since it is initialized to 0 indirectly) with this code being there. Well, except in the very rare case that we have a card that has a defualt entry that includes a memory space followed by one that has no memory space (these are extremely rare, I don't recall ever having seen one :-). Fix this by setting num_memspace to 0 in a more appropriate place. Submitted by: Coverity Prevent analysis tool

Flesh out the pccard bus_ methods with either the generic one (where it would work), or a specialized one. Most of these have been creatively stolen from pccard_nkb, which in turn stole from isa showing that generic bus_ versions of bus_{set,get,delete}_resource might be profitable. Fix a couple of minor bugs introduced in the last round of updates from NetBSD. Start on the pccard_ivar structure which will hold the resources and slot number. Add tcic as a possible attachment for pccard and rename the attachment for pcicx to pcic since the name has changed since I originally wrote this stuff. Next up: stringing together the various memory and I/O allocation/mapping primitives in i82365.c, final touches on the isa attach routine and other fun stuff in that line of attach.

memspace is set to some value by masking off bits. When these bits are equal to PCCARD_TPCE_FS_MEMSPACE_NONE, memspace will be zero, so testing for this case inside of the if statement results in dead code. We'd fail to set a value to zero that's already zero (since it is initialized to 0 indirectly) with this code being there. Well, except in the very rare case that we have a card that has a defualt entry that includes a memory space followed by one that has no memory space (these are extremely rare, I don't recall ever having seen one :-). Fix this by setting num_memspace to 0 in a more appropriate place. Submitted by: Coverity Prevent analysis tool

Some older PC Cards have a weird format for FUNCE tuples. They appear as type 0, rather than the usualy type 4. Assume that this format is from an old standard and go with it.
