From e6952593d810636f26af541b12126848483e619a Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Thu, 14 May 2015 14:31:13 +0200 Subject: kernel: Build uImage only when really needed Build the uImage file using the kernel build system only when it is really required, which is only in case KEEPUIMAGE == yes. Otherwise, just build zImage, since the Yocto build system will handle the uImage generation for us.
