A few functions are defined without being labeled as static to that file. In an effort to keep SPL as small as possible, one function needs to be moved into an #ifdef so it's only enabled when the calling function is available, and all of these can simply be marked as static.
Before: text data bss dec hex filename 50988 1053 1888 53929 d2a9 spl/u-boot-spl
After: text data bss dec hex filename 50972 1053 1888 53913 d299 spl/u-boot-spl
While not significant, a few bytes can be very helpful when SPL is limited.
