In the README file of U-boot i saw that the CFG_SDRAM_BASE (physical address ) should be 0x0. But why ?
For PowerPC, correct. Why? Because that's the way U-0Boot and Linux was designed.
For my board the SDRAM starts from 0x3000 0000.(128MB). Then how can i change. If i change how it will be effected.
The mapping is just a setting in your software. Just change your memory controller configuration and map the SDRAM to physical address 0x0000.
