From mboxrd@z Thu Jan 1 00:00:00 1970 From: Rasmus Villemoes Date: Thu, 27 Feb 2020 08:18:37 +0000 Subject: [PATCH] common/board_f.c: use #ifdefs a little more consistently Message-ID: <20200227081825.11039-1-rasmus.villemoes@prevas.dk> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Some init functions, e.g. print_resetinfo(), are conditionally defined depending on some config options, and are correspondingly conditionally included in the init_sequence_f[] array. Others are unconditionally defined and included in init_sequence_f[], but have their entire body, sans a mandatory "return 0", conditionally compiled. For the simple cases, switch to the former model, making it a bit more consistent. This also makes the U-Boot image very slightly smaller and avoids a few useless calls to no-op functions during board_init_f.
