PCMCIA cards for MPC8xx?

PCMCIA cards for MPC8xx?

[Fanny Wakizaka]

Hi,
We are developing a custom hw based on the MPC855 with support to PCMCIA. We
are using MontaVista linux kernel 2.4.17.
Could you give me some suggestions of PC Cards that worked with MPC8xx? I'm
looking for ethernet cards, modem cards and wireless cards.
Thanks in advance,
Fanny

I have used: cisco 340/350 and lucent wlan cards, 3com 3c589 lan cards,
and modems cards do not work.  The problem with modem cards had
something to do with a dependancy on serial.c (8xx uses
arch/ppc/8xx_io/uart.c).  I don't remember the exact problem now.

I've used 16550 serial ports with the m8xx_pcmcia driver.
It did not work right out of the box then (2.2), I think
some structure was shared between 8xx_io/uart.c and
the generic 16550 serial.c. And I think serial.c poked
around in some unmapped io-space.

If you get a list of working cards, maybe they could
be put in the embedded powerpc howto?

There is a patch, which allows concurent use of arch/ppc/8xx_io/uart.c
and drivers/char/serial.c
