configurations, and some ARM boards use TPL.
It looks in x86 we are using TPL in a different boot flow and this
confused me a lot in the past.
In x86 we expect TPL to load SPL then U-Boot proper. (TPL => SPL =>
However in README.TPL, it says TPL is the 3rd program loader, to be
loaded by SPL. So if my read is correct, the expected boot flow is SPL
=> TPL => U-Boot proper.
I believe only one boot flow is the correct way. So which one is correct?
