Hello,
In Samsung s3c24xx arch code, I cannot find where the SDRAM address and size information was defined. Can someone give me a lead? Thanks.
ARM boards, are now defined using Device Tree (DTS for source, DTB for binary, the compiled form). I couldn't find out for s3c24xx but, the block memory is defined as follow:
memory { reg = <0x20000000 0x20000000>; };
What about boards that is not using DTD? For the DTD based boards like above I also wondering that how to define a board with two SDRAM bands, one is at 0x30000000 - 0x34000000 and another is at 0x38000000 - 0x3C000000, should I put two reg entries in the memory section of the above dtd?
