Hi;

         I am trying to bring up u-boot-2009-08-rc1 on IXP425 board. May

I know what's the reason that the TEXT_BASE is 0x00f80000 instead of 0 or 0x50000000?

         Thanks.

Hi Teh,

usually TEXT_BASE is offset, which size depends on your requirements for stack size and memory size for malloc. If your DRAM base is 0x0 and TEXT_BASE is 0xf80000, you will have almost 16Mb for stack and malloc and your u-boot code will be linked and loaded to 0xf80000 address. 16Mb is probably too much, or your DRAM base is not 0x0.

It's only my experience with porting u-boot to Gemini arch, and I may be wrong.
