PCI1620 with an integrated memory card reader

[Onet Cristian]

Hi,

First of all I don't know if this is the right place to post this so
if it's not I apologize in advance. This will be a long story :). I
have a laptop with Texas Instruments PCI1620 PC Card controller. It
has 2 sockets: one to be used with PCMCIA cards and the other has a
built in memory card (SD, MS, MMC) reader (I think it is like any
PCMCIA memory card reader just that it's built in).

Here is the relevant output of lspci:

02:04.0 CardBus bridge: Texas Instruments PCI1620 PC Card Controller (rev 01)
02:04.1 CardBus bridge: Texas Instruments PCI1620 PC Card Controller (rev 01)
02:04.2 System peripheral: Texas Instruments PCI1620 Firmware Loading
Function (rev 01)

As you can see the problem is that the memory card reader has no
firmware loaded. I have managed to resolve this by loading the
firmware that came with the windows driver. I did this using by using
the kernel module which can be found at
http://penguin-breeder.org/kernel/download/tiumfwl.c (updated to work
with the current kernel - 2.6.20). If the firmware is not loaded I can
insert a memory card (SD) and nothing happens but after I load the
firmware and insert the SD memory card the status led shows activity
and an ide device is detected as shown in the following listings.

# pccardctl ls
Socket 0 Bridge:        [yenta_cardbus]         (bus ID: 0000:02:04.0)
Socket 1 Bridge:        [yenta_cardbus]         (bus ID: 0000:02:04.1)
Socket 1 Device 0:      [ide-cs]                (bus ID: 1.0)

 # pccardctl status
Socket 0:
  no card
Socket 1:

  Subdevice 0 (function 0) bound to driver "ide-cs"

# pccardctl ident
Socket 0:
  no product info available
Socket 1:
  product info: "TI", "Ultramedia SD", "", ""
  manfid: 0x0097, 0x1620
  function: 4 (fixed disk)

As you can see the card is detected but the problem is that it can't
be used. It is bound to the ide-cs driver because of the function id
(4 - fixed disk). I don't know if this is OK. The problem can be seen
in the kernel's output:

The SD memory card is seen as an ATA disk of 16 MB but in fact is has
a capacity of 1GB. Has anyone some suggestions about this? How should
I proceed in solving this problem? Maybe ide-cs is not appropriate for
this kind of device and a driver must be written, how are other PCMCIA
memory card readers handled? This is my last piece of hardware that is
not working under Linux and I would really like to make it work. While
searching for a solution I have seen that many users have the same
problem and it's a shame that they can't use their hardware just
because TI only provided a driver for Windows.

Thanks,
