Hi Stefan

In current CVS you will find platform independent _universal_ drivers for
Freescale peripherals. They are decoupled from particular architecture with
intention to (re)use them with all (Freescale) architectures. I find following
drivers eligible for use with MPC 5xxx:

    CYGPKG_DEVS_ETH_FREESCALE_ENET

    CYGPKG_DEVS_SPI_FREESCALE_DSPI
    CYGPKG_DEVS_DISK_MMC_FREESCALE_DSPI

    CYGPKG_IO_SERIAL_FREESCALE_ESCI_HDR
    CYGPKG_IO_SERIAL_FREESCALE_ESCI

    CYGPKG_HAL_FREESCALE_EDMA - currently for 32 channels but can be extended
tp 64.

Also from Bugzilla following I2C driver:

Likewise your MPC5xxx CAN driver could be prepared in similar fashion.
I would be happy to help you with both adapting MPC5xxx contribution for use
with universal drivers and for rendering MPC drivers such as CAN into
universal.

Regards
Ilija
