From 38c04d8e065c42254dbaca760a9e6d200321c15b Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Tue, 8 Feb 2022 11:49:48 -0700 Subject: spl: Allow disabling binman symbols in SPL When CONFIG_SPL_FIT is enabled we do not access U-Boot directly in the image, since it is embedded in a FIT which is parsed at runtime. Provide a CONFIG option to drop the symbols in this case.
