[U-Boot-Users] use bestcomm

Hi all: In my embeded linux directory , I found the bestcomm API (ELDK\ppc_82xx\usr\src\linuxppc_2_4_devel \arch\ppc\5xxx_io\bestcomm\capi) But I don't know how to use the API to handle my task which is to transfer a block of data from the FPGA's internal RAM to the PowerPC MPC5200. Pls give me a simple example of how to use the bestcomm to transfer data from FPGA Thanks zhonglei
