From 0203df36ac5ab7d2e7a7fad94edaa51594360f34 Mon Sep 17 00:00:00 2001 From: Gerome Burlats Date: Thu, 24 Jan 2019 17:53:09 +0100 Subject: [PATCH] qemu/aarch64-virt: Emulate cortex-a53 in qemu to match Buildroot config qemu_aarch64_virt_defconfig (implicitly) specifies cortex-a53, so adjust the QEMU command line to also emulate a a53 instead of a57. Also adjust the defconfig to explicitly specify a53 for consistency/clarity.
