Hello,

I hope this email finds you well.

I just saw that the previous patch (same fix, but in u-boot) made its 
way into oe-core/master, but this linux-yocto patch here didn't.

Would you have any feedbacks about it? Something to be 
reworked/rephrased, otherwise I'd say this patch is needed just as much 
as the u-boot one.

Also, my original intent was to provide a fix a problem I faced in 
Whinlatter, so backporting those patches should be needed as well. I 
will work on it, of course, but I'd like first to make sure the 
linux-yocto patch is not left outside.

Thanks!
