microblaze: spl: Do not call mem_malloc_init and use early alloc
This patch has some parts connected together: - Use _gd in bss section which is automatically cleared Location at SPL_MALLOC_END wasn't cleared at all - Use MALLOC_F_LEN(early alloc) instead of FULL MALLOC (mem_malloc_init is not called at all) - Simplify malloc and stack init. At the end of SPL addr is malloc area and below is stack Signed-off-by: Michal Simek <michal.simek@xilinx.com>
