In general we should avoid calling malloc() and free() repeatedly in
U-Boot lest we turn it into tianocore. In SPL this can make SPI flash
unusable since free() is often a nop and allocation space is limited.
In any case, these seems no need for malloc() since the number of bytes
is very small, perhaps less than 8.
