Hi,
I'm a bit confused about the stack location after calling
spl_relocate_stack_gd(). Looking at the code of this function I see that
the stack pointer is in the simple_malloc heap before the global data.
That means that the stack is growing downwards into the heap. Also the
malloc_limit includes the global data memory. This looks quite odd.
Wouldn't it be better to set the stack base the same address as malloc_base?
In the documentation[1] there is also a picture (DRAM SPL after
relocation) that illustrates this. The Stack region is just placed wrong
there and never used as the stack grows downwards. It must be above
malloc_base.
If you think my thoughts are correct I can prepare a patch.
thanks,
ron
