[U-Boot] Can anyone help me to solve the stack problem of U-boot? Urgent~

[吳志峰]

Dear all:

I'd solved this problem.
I define a global symbol at link script and used this global symbol to set
up stack pointer.
This global symbol indicated the end address of U-boot.
I also changed the globla gd pointer address and memory allocation address.

Thanks....

Hope this introduction "U-boot Porting Guide for NDS32 based SoC"  may help
you.
The stack setup of NDS32 is similar as ARM.
Please also read the document at first. :)
