- The qemux86 port for helloworld-baremetal builds in the standard way, however,
it uses NASM syntax for the startup code, hence we include a dependency to
nasm-native, QEMU forces us to use an ELF file rather than a bin file to boot
from this architecture using the -kernel parameter.
- QEMU refuses to boot using the -kernel parameter for files containing an ELF64
header [1], instead, it requires a multiboot2 compatible image.
We could create an image that contains a multiboot2 header by piggybacking
into grub2-native, specifically grub-mkrescue, but it requires some extra
runtime dependencies (xorriso which is currently part of meta-oe), and assumes
a grub installation exists on the host.
Due to host contamination and dependency complications, we dont rely on grub2,
but rather do this process manually instead, the x86-64 port contains a stage1
bootloader, stage2 bootloader and a 64 bit baremetal app (multiboot2
compatible), booting into real (16 bit), protected (32 bit) and long (64 bit)
modes, eventually running the helloworld-baremetal app. This is the reason why
we need the code changes to use a separate Makefile, and create an image
specifically for qemux86-64.

This is the result of automated script conversion:
scripts/contrib/convert-overrides.py <oe-core directory>
converting the metadata to use ":" as the override character instead of "_".

To better align with upstream and mimic how images
are built, use do_image and do_image_complete instead
of do_deploy to populate artifacts on DEPLOY_DIR_IMAGE.

IMGDEPLOYDIR is not being expanded anymore, this causes
do_rootfs to fail because it can't create the manifest file,
we can set it to the default being set on image.bbclass since
this is only a decoy function anyway to satisfy testimage,
this makes do_rootfs happy and allows it to continue.

Create HelloWorld examples that run on several of the QEMU architectures
supported by the build system.
This recipe can be used by anyone to understand how baremetal applications
can be built using OpenEmbedded and how the wiring to set them up could be.
This should also facilitate creating/extending the OE testing infrastructure
to allow baremetal applications or RTOSs to be tested in the same way that
Linux currently is.
This can easily be extended to work on other MACHINES in the future.
To run this example:
$ source oe-init-buildenv
$ bitbake-layers add-layer ../meta-skeleton
# TCLIBC="baremetal" would work as well
$ echo "TCLIBC = \"newlib\"" >> ./conf/local.conf
$ echo "MACHINE = \"qemuarm64\"" >> ./conf/local.conf
$ bitbake baremetal-helloworld
$ runqemu
runqemu - INFO - Running bitbake -e ...
runqemu - INFO - Continuing with the following parameters:
KERNEL: [tmp/deploy/images/qemuarm64/baremetal-helloworld-qemuarm64.bin]
