The boot-wrapper has had periodic updates over the last few years, and with
each addition becomes increasingly in need of some larger scale cleanup to keep
it clear and maintainable.
While looking over Jaxson Han's ARMv8-R AArch64 series [1] I realised there are
a number of existing issues and design warts that we need to clean up before it
becomes harder to do so.
These patches address some existing issues with the boot-wrapper, and
restructure the codebase to make it easier to navigate. I intend to merge these
in the next few days if there are no objections, and will follow up with some
further rework which should make it easier to add ARMv8-R AArch64 support atop.
Thanks,
Mark.
