Through more testing on my end, it seems that something is not as it appeared at first glance. Switching branches to build this patch and then back to my main development branch resulted in the same strange malloc behavior that I thought I was fixing here, which only resolved after reverting this patch. I'd like to understand why SPL_CLEAR_BSS needs to be called in both SPL and u-boot, if someone better versed in what's going on here can take the time.
