TEMAC support of Uboot on ML403

Dear all,
Does anyone know that whether U-boot can support Xilinx TEMAC core to tftp 
the Linux kernel or not. In my design I am using TEMAC instead of the 
normal enet. While I found that in the Xilinx u-boot tree, there is only a 
directory for xilinx_enet instead of xilinx_temac. I am not sure if I am 
right, but I remember a long time before, there was a patch for supporting 
Xilinx TEMAC in U-boot. 

Any suggestion will be appreciated a lot for this topic. Thank you in 
advance for your telling.

BR
Ming
