Now that your changes are in Linus' tree, I started looking at
restructuring my code. I sense a small problem though:

Unless I'm mistaken, it seems that pxa2xx_drv_pcmcia_add_one() doesn't
call pxa2xx_configure_sockets(), leaving the sockets disabled.

There is several ways to solve this one:
- Add the call to pxa2xx_configure_sockets() to _add_one()
- Do the MECR access in the pxa2xx_viper driver,
- export pxa2xx_configure_sockets() and do the call locally.

What would be your preferred solution?
