Hello

As a maintainer, viewing all boot including a specific hardware/driver.
Does my xxxx driver works everywhere ?

Recent example:
- I have added support for PRNG/hash on sun8i-ce, I want to check all boots with this driver.
More complex recent example:
- since commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx delay config") many board could loose network, I want to see all boots including this patch with this PHY.
