[v9,0/7] Add barebox bootloader support (and testing)

This adds support for the barebox bootloader (and tools) to oe-core.

In order to have proper testing, this extends oe-selftest to allow
basic testing of bootloaders. While at it, cover both barebox and u-boot.

v9:
  * move BAREBOX_CONFIG hunk back to corresponding patch

Enrico Jorns (5):
  barebox: set default BAREBOX_CONFIG for qemu machines
  oeqa/utils/qemurunner: support ignoring vt100 escape sequences
  oeqa: support passing custom boot patterns to runqemu
  oeqa/selftest/cases: add basic u-boot test
  oeqa/selftest/cases: add basic barebox tests

Marco Felsch (2):
  barebox: add initial support
  barebox-tools: add initial barebox tools support

Hello Enrico,

Since this patch series introduces a new class for compiling barebox-based
bootloaders, it would be nice to have some documentation for it.

Openembedded-core classes are documented in yocto-docs[1], and documentation
patches are sent to docs@lists.yoctoproject.org.

Could anyone, preferably the author of the class, take some time to document the
usage of the class in yocto-docs/documentation/ref-manual/classes.rst, and the
variables the class defines (especially the ones that can be overridden for user
customization) in yocto-docs/documentation/ref-manual/variables.rst?

That would be greatly appreciated. I can help if needed.

Regards,
Antonin

thank you for reaching out regarding the documentation of the barebox.bbclass.

I was on vacation last week and still have some year-end tasks to take care of
this week, so I'm not sure how soon I'll get to it.
However, I’m happy to contribute the corresponding class documentation.

Thanks a lot! I'll get back to you in case something is unclear (e.g. where to put which
information). Luckily all the documentation is rst which I am quite familiar with

Ideally, some time before the next Walnascar release would be great.

I've created a bug to track this:
