partitions info of CF flash

hi
    My evaluation board is Xilinx ML300. RTOS is MVL pro3.0.
    I have two problems.
    One is how I pass the partition info to kernel. There are three parts in CF flash. The first saves .cfgs with FAT FS(which fs should i select? msdos/vfat). The second saves zImage. The last one is used as root device with ext2 fs(a better one?). I have looked the code in drivers/block/xilinx_sysace/adapter.c. I find it seems only to initialize the CF device without the partitions.
    The other is that where can i get the driver for uart lite(xilinx_uartlite.c).

Thanks
