Subject: [PATCH] Assume TPL support for ATF when compiling U-Boot without TPL
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Broadcom's U-Boot behaviour depends on compilation time check whether
TPL was compiled with or without ATF support. There is no proper runtime
check.

When compiling just U-Boot (without SPL & TPL) there is no way to tell
if it's going to work with TPL with or without ATF support.

Modify code to blindly assume ATF support in TPL in such cases. It seems
to be always true for Broadcom and we need some assumption as we don't
deal with compiling SPL or TPL.
