(previous reply wasn't caught by patchwork, adding more info) Yes, pram is used to reserve small memory from the top of u-boot memory, not necessarily the top of total memory. For example, a 32-bit u-boot with large memory. This patch deals with carving memory from the end of memory, which could be far away from u-boot top. Even in system with small memory, it is still correct, because pram reserves memory from the _top_ of u-boot and this mechanism reserved memory is hidden from u-boot.
