[Qemu-devel] [PATCH v5 07/14] tests: Add bbc:microbit / nRF51 test suite
Posted by Steffen Görtz 7 years, 2 months ago 
The microbit-test includes tests for the nRF51 NVMC
peripheral and will host future nRF51 peripheral tests
and board-level bbc:microbit tests.

If you could do me a big favour, then please try to write new qtests
without the global_qtest variable. I.e. move the qtest_initf into the
test_nrf51_nvmc function and pass around the local test state variable
there to qtest_writel() and friends. I just started yet another clean up
attempt for some other files, e.g. see here:

 https://lists.gnu.org/archive/html/qemu-devel/2018-11/msg02196.html

(but if this is too much cumbersome right now for you, I also won't
object this patch in the current shape - we can still clean this up later)

I would like to leave the test like this at the moment. We will add additional devices in the future and i would like to postpone refactoring of the test until the current patch series is merged.
