However, as explained in commit a9819b9e33bd ("ARM: tegra: p2771-000: increase max DRAM bank count"), the platform can have a large number of unusable chunks of memory (up to 1024), so a total of 1026 DRAM banks are needed to describe the worst-case situation. In practice the number of DRAM banks needed will typically be much lower, but we should be prepared to properly deal with the worst case.
