You could download LSDK 21.08 pre-built firmware image with the following command.

wget https://www.nxp.com/lgfiles/sdk/lsdk2108/firmware_ls1046ardb_qspiboot.img

Then deploy it on the alternate bank of QSPI flash on the target board.

=>tftp 0xa0000000 firmware_ls1046ardb_qspiboot.img

=>sf probe 0:1

=> sf erase 0 +$filesize

=>sf write 0xa0000000 0 $filesize

Which version LSDK are you using? How did you generate the boot firmware image?

DDR initialization should be in ATF booting up stage not in u-boot.
