This function is used before jumping to U-Boot, but in that case we don't always want to disable caches.

In which usecase exactly is this applicable please ? :)
This is sort-of related to "Enable detecting when U-Boot is started from SPL" so there are some details there.
I was able to get SPL to enable the cache and leave it on all the way through the verified boot flow (read-only and read-write U-Boot) and it saved about 600ms. So in short this refactor allows you to jump into U-Boot with the cache still enabled.
Sounds good, thanks for clarifying !
