[PATCH v3] Nokia RX-51: Add automated test for running RX-51 build in qemu

Pali Rohár pali at kernel.org
Sun May 17 14:38:22 CEST 2020

This patch contains test/nokia_rx51_test.sh script which automatically
download and compile all needed tools in local temporary directory to
generate a simple MTD images for booting Maemo kernel image by U-Boot from
RAM, eMMC and OneNAND. MTD images are then run in virtual n900 machine
provided by qemu-linaro project.

This script does not need any special privileges, so it can be run as
non-root nobody user.

It can be used to check that U-Boot for Nokia N900 is not broken and can be
successfully booted in emulator.

Script is registered to .azure-pipelines.yml, .gitlab-ci.yml and
.travis.yml so it would be automatically run on those CI services.

Signed-off-by: Pali Rohár <pali at kernel.org>
Changes in v3:
* Fix job for Azure
Changes in v2:
* Fix apt dependences for Travis CI
* Move definition of Travis job into own section
* Add definition for Azure and Gitlab CI services
* Add script to MAINTAINERS file
* Build U-Boot binary in test script too
* Show error message when some dependency for script is missing
* Fix addresses for booting kernel from OneNAND
* Do all stuff in nokia_rx51_tmp temporary directory
* Use upstream mformat (from mtools) for generating FAT32 MBR filesystems
  (instead of mkfs.fat from dosfstools with custom patches)
* Show more verbose log messages
* Do not use sudo, instead run parts of script under fakeroot
  (fakeroot just run binary with own LD_PRELOAD library which emulates
   mknod() function for later usage by stat() function)
* So script can be now run as non-root nobody user and it put all stuff
  in nokia_rx51_tmp temporary directory, so can be run locally without
  any issue.
