So, SPL is where things get, ahem, fuzzy.  While I don't want to
encourage boundless growth in U-Boot proper, we aren't exactly size
constrained (but rather, functional/logical constrained).  But in SPL,
yes, we have many platforms with 32/64/128 kilobyte hard limits (and
some smaller) and we can't always shove in a "TPL" before SPL either.
So in SPL we do make use of platform data instead.  While not the
smallest size constraint, am335x_hs_evm is a reasonable thing to look at
in this case.
