Mount SRAM card without CIS

[Joe Knapp]

Dear MTD team,

I have been searching for many hours now on how to enable a 256 KByte
PCMCIA SRAM card. Some details:

Linux 2.6.35-30-generic #56-Ubuntu SMP Mon Jul 11 20:01:08 UTC 2011
x86_64 GNU/Linux

lspci:
03:06.0 CardBus bridge: Texas Instruments PCI1225 (rev 01)
03:06.1 CardBus bridge: Texas Instruments PCI1225 (rev 01)

dmesg after inserting the card and running /lib/udev/pcmcia-socket-startup:
[142469.220134] pcmcia_socket pcmcia_socket0: pccard: PCMCIA card

I have successfully used this HW to mount a CompactFlash device via a
PCMCIA to CF adapter, and the SRAM card works correctly in some other
test equipment. So, I believe that the HW is OK.

I have tried some variations to /etc/pcmcia/config, including:
device "pcmciamtd" needs_mtd
  class "memory" module "pcmciamtd"

card "Anonymous Memory"
  anonymous
#  bind "memory_cs"
  bind "pcmciamtd"

card "Memory Card"
  function memory_card
#  bind "memory_cs"
  bind "pcmciamtd"

Can you please provide some clues as to the current method to enable a
SRAM card without CIS?

Thank you in advance,

Joe Knapp
