Hi Bruce,
Please pardon my lack of good knowledge here as I don't deal with OE/Yocto very
often.
So what are the options we have here?
Given dependency on the Linux kernel v5.5 where that change
("nsim_hs_defconfig" -> "haps_hs_defconfig") was done I'd say whatever active
branches of version above 5.5 exist would be good to get it.
Looking at https://git.yoctoproject.org/cgit/cgit.cgi/yocto-kernel-cache/ I'd
think these are: 5.10, 5.13 & "master" branches.
-Alexey

Looks good to me.
What branches were you targetting for the change ?
