So if  I understand you correctly both the PBI and barebox PBL got mapped to the SRAM (which I guess may be the OCRAM1 if i refer to the address above 0x10000000) and get executed sequentially.

Based on U-boot, RCW+PBI (at 0x40000000) which specifies 09570604 40100000 (address of U-boot), I would have thought that the address needed to be the exact start address of the barebox PBL in QSPI. Apparently not. 

So If I burn the image barebox-ls1046ardb-qspi.image at address 0x40000000 (start of QSPI flash) by using U-boot, it shall boot on power on.

Thanks.
