TPL builds today don't need to call into firmware or set up the MMU (if this changes, it should be controlled through a config option whether to include this or not), but include the needed support code for this anyway.
Even for a feature-rich TPL (including DM support as for the RK3368), this equates to a size difference of approx. 10% in TPL binary size: - without this change: text data bss dec hex filename 23635 3112 24 26771 6893 tpl/u-boot-tpl - with this change: text data bss dec hex filename 21583 3112 24 24719 608f tpl/u-boot-tpl
