Re: [U-Boot] [PATCH] spl: add debug print for early malloc usage

To find out how big the early malloc heap must be in SPL, add a debug print statement that dumps its usage before switching to relocated heap in spl_relocate_stack_gd() via CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN.

Shouldn't this use %p ?

ptr -= CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN;
gd->malloc_base = ptr;
gd->malloc_limit = CONFIG_SPL_STACK_R_MALLOC_SIMPLE_LEN;
