DDR Memory Controller
Chip select interleaving is supported for the memory controller, and is programmed in
DDR_SDRAM_CFG[BA_INTLV_CTL]. Interleaving is supported between chip selects 0 and 1. When
interleaving is enabled, the chip selects being interleaved must use the same size of memory. One extra bit
in the address decode is used for the interleaving to determine which chip select to access.
