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

These should be set via Kconfig - e.g. default values for your arch, or perhaps individual values in the defconfig files. At present this breaks when driver model is enabled by default.
Can you please take a look?
