From f58e94602edda7aaa0173e1437bf5972004e133d Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Thu, 10 May 2018 07:15:52 -0400 Subject: [PATCH] at91: Minor tweaks to SPL logic for space savings on smartweb - spl_board_init is empty on smartweb so drop that function - When CONFIG_AT91SAM9_WATCHDOG is set we do not disable the watchdog in SPL and instead let full U-Boot handle it. Instead of an empty function just do not call a function.
