It is tested on the Katmai (440SPe) eval board and works fine with the following DIMM modules: - Corsair CM2X512-5400C4 (512MByte per DIMM) - Kingston ValueRAM KVR667D2N5/512 (512MByte per DIMM) - Kingston ValueRAM KVR667D2N5K2/2G (1GByte per DIMM) This patch also adds the nice functionality to dynamically create the TLB entries for the SDRAM (tlb.c). So we should never run into such problems with wrong (too short) TLB initialization again on these platforms.
