From 90808c2a055b1e6332db307ca34ab682be60cfbf Mon Sep 17 00:00:00 2001
From: Alexander Graf <agraf@suse.de>

Subject: [PATCH] hw/arm/boot: Increase fdt alignment
The Linux kernel on aarch64 creates a page table entry at early bootup
that spans the 2MB range on memory spanning the fdt start address:
[ ALIGN_DOWN(fdt, 2MB) ... ALIGN_DOWN(fdt, 2MB) + 2MB ]
This means that when our current 4k alignment happens to fall at the end
of the aligned region, Linux tries to access memory that is not mapped.
The easy fix is to instead increase the alignment to 2MB, making Linux's
logic always succeed.
