From a69814c815b9a1a027f461ef26dbe7b2b8e258e4 Mon Sep 17 00:00:00 2001 From: T Karthik Reddy Date: Tue, 20 Aug 2019 09:30:57 +0530 Subject: [PATCH] arm64: zynqmp: Set initrd_high to as high as possible This patch is setting up the initrd_high to as high as possible by leaving max stack size for u-boot so that bigger rootfs can also be loaded by u-boot for booting kernel.
