    Hello,

    I would like to know if a linux driver exists that uses the UPM (User
    Programmable Machine) of the PowerPC (I use the MPC8247) to control a
    Compact Flash as in the following application notes :

    If not, what would you suggest to implement a Compact Flash interface to the
    MPC8247 (this one doesn't have the PCMCIA interface) ? I have looked at PCI
    to ATA chips but the only one available in Canada I found and supported by
    Linux (Silicon Image Sii0680ACL144) dissipates 1.2W (almost as much as the
    PowerPC itself...). This is way too much for my embedded platform.

    Thanks,
