Supported external SDRAM (MT48LC4M32B2B5-6AIT:L) on STM32H745I-DISCO dev board. Though MT48LC4M32B2B5-6AIT:L SDRAM itself provides 32-bit data bus, STM32H745I-DISCO board routes only DQ[15:0] bits. Thus only half of the memory can be accessed: the accessible memory configuration is only 1 Meg x 16 x 4 banks instead of 1 Meg x 32 x 4 banks. Thus the accessible memory size is 8 MBytes.
