Hi,
Please let me know if Uboot uses DMA for any of its operations during board
bootup.
Please let me know if Uboot has DMA support and if yes how??
Thanks in advance.
Best Regards,
Nikhil

U-Boot supports quite a few different processor families with an a large
range of variants over hundreds of boards. I have not checked, but I'm
pretty confident the answer is "yes" for at least one board in there and
for at least some interpretation of "bootup."
>> Please let me know if Uboot has DMA support and if yes how??
Very carefully. If you want to use DMA on your processor and your
board, you should do it very carefully as well.

Less flippantly, you have the source. Search it and learn. We don't
have enough information to give you any better advice.
