From 0979f7ce1eea73c80e6f858a803106660507d1e3 Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Mon, 23 Apr 2018 07:59:49 +0200 Subject: [PATCH] riscv: nx25: Enable distro boot Distro boot allows for a common boot path on systems that allow distributions to easily boot from a default configuration. This patch enables distro boot for the nx25-ae250. Hopefully this can serve as a good example for new boards, so they enable it as well.
