From 9553d16fa671b9621c5e2847d08bd90d3be3349c Mon Sep 17 00:00:00 2001 From: Amit Daniel Kachhap Date: Mon, 30 Mar 2020 17:11:38 +0530 Subject: [PATCH] init/kconfig: Add LD_VERSION Kconfig This option can be used in Kconfig files to compare the ld version and enable/disable incompatible config options if required. This option is used in the subsequent patch along with GCC_VERSION to filter out an incompatible feature.
