+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.
