[PATCH v2] Nokia RX-51: Add booting from UBI into test script

Pali Rohár
2022-09-15T19:00:19Z

Compile U-Boot with UBI/UBIFS support according to doc/board/nokia/rx51.rst
instructions and add test case for loading kernel image from UBI volume.

Signed-off-by: Pali Rohár <pali@kernel.org>
---
Changes in v2:
* Fix issue that script fails at the first run
- File zImage-2.6.28-omap1 needs to be unpacked earlier

I have tested it localy from the clean git checkout and test script
passed at the first run.
