From 3d6bf693d8bc63f2e5eca7373916c4871f8ffd66 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Wed, 8 Nov 2017 22:05:27 +1100 Subject: powerpc/boot: Only build uartlite if XILINX_VIRTEX=y The serial code in uartlite.c only matches if we find one of two Xilinx (xlnx) nodes in the device tree, there's no need to build or link the code on other platforms. As far as I can tell CONFIG_XILINX_VIRTEX is the appropriate symbol to use to conditionally compile the code.
