PCMCIA support for S3C2410

[Ed Daelli]

Hello all,

I am working in porting pcmcia support for the s3c2410 processor under
2.6.15. I am working on a SMDK2410 dev kit.
I have pasted a log with some sys info about my system.
I am using a PD6710 controller and modified the i82365.c driver to work with
my specific hardware.
I can recognize card insertions and removal, am able to map memory and io
and get CIS information from the cards.
My problem is when I insmod the drivers for the specific cards, I get some
messages that the socket was attached to the driver with the correct IRQ and
port, but I cannot use the device.
I am using 2 different types of cards:
1. Serial. The serial_cs driver attaches to the socket and uses /dev/ttyS0,
but I cannot communicate with the modem,
2. Ethernet. The 3c589_cs driver attaches to the socket and uses eth1, but I
cant talk to the device.
Hare is some info:
