From 222dc0ad912370a620172a781a1c429dae01ab08 Mon Sep 17 00:00:00 2001 From: Josef Schlehofer Date: Sun, 13 Dec 2020 15:02:36 +0100 Subject: [PATCH] armvirt/64: change it to cortex-a53 instead of generic Package architecture aarch64_generic [1] can be used just with three devices. One is NanoPI R2S and then there are two development boards from NXP. Let's change armvirt/64 to Cortex A53 (aarch64_cortex-a53) [2]. It has wider support by multiple devices like NanoPI Neo Plus2/Core2, ESPRESSObin, Pine64, and Raspberry Pi 2&3. While looking at ARMvirt/32 it has set CPU_TYPE and CPU_SUBTYPE to be arm_cortex-a15_neon-vfpv4 [3]. It has support to devices like Linksys EA8500 v1, Linksys EA7500 v1, Netgear D7800, Netgear R7500 and so on. Tested with: qemu-system-aarch64 -m 1024 -smp 2 -cpu cortex-a57 -M virt -nographic \ -kernel openwrt-armvirt-64-Image-initramfs Successfully compiled and booted.
