I like that we're starting down this path.  But can you explain why we
need each of these changes:

Having gone down the path of disabling output in SPL before due to size
constraints I didn't need to modify those files (but it was on an older
version)

In this case I just said we only need those functions (and their
strings!) when we have SPL_SERIAL available.  It may be worth
re-checking what parts of this file we really need available in SPL
even.

We should be able to be fine without a preloader_console_init() func I
think.
