These are used by both the armsr (EFI boot) and
layerscape targets for phylink-controlled SFP
support on NXP DPAA2 platforms (LS1088,LS2088,LX2160).
This is in place of commit a7bd96c98f8f
("layerscape: add patches for SFP support on DPAA2 platforms")
in the main branch. armsr in main started at kernel 6.1
so there is not an equivalent 5.15 commit to cherry pick.

This target generates images that can be used on ARM machines with EFI
support (e.g EDKII/TianoCore or U-Boot with bootefi).
There are two subtargets:
- armv7 for 32-bit machines
- armv8 for 64-bit machines
The kernel and filesystem images can also be used directly by QEMU:
Run with qemu-system-arm
# boot with initramfs embedded in
qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armsr-armv7-generic-initramfs-kernel.bin
# boot with accel=kvm
qemu-system-arm -nographic -M virt,accel=kvm -cpu host -m 64 -kernel
openwrt-armsr-armv7-generic-initramfs-kernel.bin
# boot with a separate rootfs
qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armsr-armv7-generic-kernel.bin \
-drive file=openwrt-armsr-armv7-generic-ext4-rootfs.img,format=raw,if=virtio -append 'root=/dev/vda rootwait'
# boot with local dir as rootfs
qemu-system-arm -nographic -M virt -m 64 -kernel openwrt-armsr-armv7-generic-kernel.bin \
-fsdev local,id=rootdev,path=root-armsr/,security_model=none \
-device virtio-9p-pci,fsdev=rootdev,mount_tag=/dev/root \
-append 'rootflags=trans=virtio,version=9p2000.L,cache=loose rootfstype=9p'
Run with kvmtool
# start a named machine
lkvm run -k openwrt-armsr-armv7-zImage -i openwrt-armsr-armv7-rootfs.cpio --name armsr0
# start with virtio-9p rootfs
lkvm run -k openwrt-armsr-armv7-zImage -d root-armsr/
# stop "armsr0"
lkvm stop --name armsr0
# stop all
lkvm stop --all
The multi-platform ARMv8 target can be used with QEMU:
qemu-system-aarch64 -machine virt -cpu cortex-a57 -nographic \
-kernel openwrt-armsr-armv8-generic-initramfs-kernel.bin \
With a EDKII or U-Boot binary for the QEMU ARM virtual machines, you can use these
images in EFI mode:
32-bit:
gunzip -c bin/targets/armsr/armv7/openwrt-armsr-armv7-generic-ext4-combined.img.gz > openwrt-arm-32.img
qemu-system-arm -nographic \
-cpu cortex-a15 -machine virt \
-bios bin/targets/armsr/armv7/u-boot-qemu_armv7/u-boot.bin \
-smp 1 -m 1024 \
-device virtio-rng-pci \
-drive file=openwrt-arm-32.img,format=raw,index=0,media=disk \
-netdev user,id=testlan -net nic,netdev=testlan \
-netdev user,id=testwan -net nic,netdev=testwan
64-bit:
gunzip -c bin/targets/armsr/armv8/openwrt-armsr-armv8-generic-ext4-combined.img.gz > openwrt-arm-64.img
qemu-system-aarch64 -nographic \
-cpu cortex-a53 -machine virt \
-bios bin/targets/armsr/armv8/u-boot-qemu_armv8/u-boot.bin \
-smp 1 -m 1024 \
-device virtio-rng-pci \
-drive file=openwrt-arm-64.img,format=raw,index=0,media=disk \
-netdev user,id=testlan -net nic,netdev=testlan \
-netdev user,id=testwan -net nic,netdev=testwan
One can obtain other EFI/BIOS binaries from:
- Distribution packages (such as qemu-efi-arm and qemu-efi-aarch64 in Debian)
- Community builds, like retrage/edk2-nightly: https://retrage.github.io/edk2-nightly/
