The missing piece here is the SDRAM driver. This is a big piece as
U-boot require the SDRAM to run. As of now, I am enhancing the existing
SDRAM drivers to ensure its compliance with the coding standard. 

But nevertheless, it poses another challenge when come to license. The
driver is currently licensed under BSD-3 clause. Wonder can we upstream
BSD-3 clause code? Any advise would be appreciated.
