baremetal-helloworld: Enable x86 and x86-64 ports

2023-01-12T23:08:58+00:00

- 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. $ runqemu nographic Booting from ROM..

Convert to new override syntax
