From: Emanuele Ghidoli <[email protected]> Use alias-based RAM probing to detect different memory configurations on Toradex iMX95 modules using LPDDR5. The address wrap-around is not linear on LPDDR5 modules: address bits above the module capacity alias back with some low address bits XORed (bit 32 -> XOR 0xc000), as measured on 4GB and 8GB modules.
