[U-Boot] U-Boot on Xilinx Virtex platforms

Hi,

I'm new to Xilinx world, so please bare with my ignorance.

Looking at u-boot Xilinx files I see that u-boot does not perform SDRAM initialization. SDRAM is apparently initialized by FPGA code. Is that correct ?

Another question is whether u-boot on Virtex can start executing from NOR flash or should be copied to SDRAM by some first level bootloader ?

Thanks a lot.

Felix.
