zynqmp: spl: support DRAM ECC initialization
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.
