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.

Usually, yes.

Yes.  Either method works.
