[PATCH v4 5/7] oeqa: support passing custom boot patterns to runqemu

Enrico Jörns
2024-09-10T07:21:10Z

From: Enrico Jorns <ejo@pengutronix.de>

This allows defining non-standard patterns from QEMU tests just as they
are already supported by the testimage.bbclass.

Will allow testing non-Linux shells in QEMU, too (e.g. a U-Boot shell or
another bootloader shell).
