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.
