From d4bb3b376223c72b49c3a2bdcce896557d997e6b Mon Sep 17 00:00:00 2001 From: Alex Kiernan Date: Thu, 19 Apr 2018 04:32:53 +0000 Subject: [PATCH] spl: ti: Avoid serial calls when serial support is disabled If CONFIG_SPL_SERIAL_SUPPORT is not set, then the build will fail: board/ti/am335x/built-in.o: In function `spl_start_uboot': board/ti/am335x/board.c:247: undefined reference to `serial_tstc' board/ti/am335x/board.c:247: undefined reference to `serial_getc' Avoid the calls to the serial functions in that case.
