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 or chip
selects 2 and 3. In addition, interleaving between all four chip selects can be enabled. When interleaving
is enabled, the chip selects being interleaved must use the same size of memory. If two chip selects are
interleaved, then 1 extra bit in the address decode is used for the interleaving to determine which chip
select to access. If four chip selects are interleaved, then two extra bits are required in the address decode.
