From e0418347f9aa0f5099dfc1dac8eafceb98e38ccf Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Wed, 25 Sep 2019 11:00:17 +0200 Subject: microblaze: Setup initrd_high and fdt_high at run time Setup initrd_high and fdt_high to be placed in lowmem space for kernel to be able to reach it. Values are setup at run time to ensure that the same setting can be used on different memory setup. Do this setting only when variables are not Similar run time detection was done for Zynqmp and Versal.
