You also need to update KBUILD_DEFCONFIG to use the haps defconfig now. Also perhaps as an addon change switch nsim_700_defconfig to dwuart too for consistent uart settings for all processor builds in kernel/nsim (otherwise you need to document this disparity in various github wiki pages) -Vineet _______________________________________________ linux-snps-arc mailing list linux-snps-arc@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-snps-arc
