Make clear that when the user selects CONFIG_SYS_SPL_MALLOC_START the full malloc will be used in SPL and also that this malloc pool can be used prior to configuring SPL.

This is the 'full' malloc(). So I think you need to mention that this is set up by spl_init(), and before that, the simple malloc() can be used if CONFIG_SYS_MALLOC_F is defined.

There is great potential for confusion so I'd like the docs to be very clear.

            CONFIG_SYS_SPL_MALLOC_SIZE
            The size of the malloc pool used in SPL.
