From dec5777fffcc6f9e97a20bc23fc7353b30b70ed5 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Sat, 7 Oct 2023 15:13:07 -0400 Subject: [PATCH] command.h: Add a U_BOOT_LONGHELP macro In order to be able to discard unused long help texts without further linker lists, add a macro for defining the long help messages which uses __maybe_unused. This allows us to discard them as unreferenced as part of the link.
