Intel i3-10110u and i7-10710u

Hello,
 
I’m trying to make sense of the information on the Intel website, and the Coreboot source code, regarding the i3-10110u and i7-10710u processors.
 
If I have interpreted things correctly, these are Comet Lake U devices and that the Comet Lake U DDR4 RVP reference board is supported as a variant within the Coffee Lake RVP.  It appears that the low-power Comet Lake U LPDDR3 board isn’t supported.
 
I can’t see anything in the sources that would confirm / deny whether those two specific processors are supported.
 
Can anyone point me in the right direction?
 
Thanks,
 
Andy.
