linux-qoriq Oldest_Kernel incompatibility in scarthgap

I'm using the linux-qoriq recipe in the scarthgap branch of meta-freescale =
to build an image for a LS1046A processor. When I build I get this warning

> WARNING: linux-qoriq-5.10.52+git-r0 do_compile: linux-qoriq: OLDEST_KERNE=
L is "5.15" but the version of the kernel you are building is "5.10.52+ga11=
753a89ec6+p0" - therefore glibc as built may not be compatible with this ke=
rnel. Either set OLDEST_KERNEL to an older version, or build a newer kernel=
.

Is updating to walnascar (Yocto 5.2) or whinlatter (Yocto 5.3) the best way=
 to resolve this issue? I was hoping to stay on an LTS branch of Yocto, so =
I'm wondering why 5.10 was used in scarthgap.
