As per PPA verification patch for eMMC/SD and NAND:

 	  If the PPA header firmware locate at XIP flash, such as NOR or
 	  QSPI flash, this address is a directly memory-mapped.
 	  If it is in a serial accessed flash, such as NAND and SD
 	  card, it is a byte offset.

CONFIG_SYS_LS_PPA_ESBC_ADDR is used to provide offset on eMMC/SD and NAND.
