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.

regards,
Darius A.
