Use the ZDMA channel 0 to initialize the DRAM banks. This avoid spurious ECC errors that can occur when accessing unitialized memory. The feature is enabled by setting the option CONFIG_SPL_ZYNQMP_DRAM_ECC_INIT and providing the following data: SPL_ZYNQMP_DRAM_BANK1_BASE: start of memory to initialize SPL_ZYNQMP_DRAM_BANK1_LEN : len of memory to initialize (hex) SPL_ZYNQMP_DRAM_BANK2_BASE: start of memory to initialize SPL_ZYNQMP_DRAM_BANK2_LEN : len of memory to initialize (hex) Setting SPL_ZYNQMP_DRAM_BANK_LEN to 0 takes no action.
