Here [1] it says the name of the SoM is PCM-060 , what is PCL-060 ?

This differs only by the connector. PCM variants are pluggable and PCL variants are direct soliderable to the carrier board.
Copied from [1]: The PCL-060 System On Module is a connector-less, BGA style variant of the PCM-060/phyCORE-AM335x R2 SOM. Unlike traditional Phytec SOM products that support high density connectors, the PCL-060 SOM is directly soldered down to the phyBOARD-Wega AM335x using Phytec's Direct Solder Connect technology (DSC). This solution offers an ultra-low cost Single Board Computer for the AM335x processor, while maintaining most of the advantages of the SOM concept.

Ah damn, this looks like a consistency problem is coming up. We have multiple PCM* SoMs in U-Boot, one PCL* SoM and now another PCL/PCM SoM. But the PCL063 isn't even manufactured in variant with connectors, so I guess we can ignore that one.
I wonder whether we should stick to PCM* for all of the Phytec SoMs for consistency sake and document that PCL060 is also supported or maybe there's a better way ?
Does PCX/PCx makes sense? But we have the same problem with variscite [1] SoM's (either SODIMM or solderable).

PCX would introduce another option, in addition to PCM/PCL, one which cannot be easily found on the internet, so I'd like to avoid that. I am banking toward the sticking with PCM where possible (simply because that's what $searchengine spits out first when you look for that SoM, and because we already have plenty of PCM-nnn SoMs), but maybe someone has a better idea .
why not simply use the full name of the module instead?
- phyCORE-AM335x - phyCORE-AM335x R2
I did the same for the phyCORE-RK3288. There is no real difference between a PCM and PCL SOM. You can take look at the barebox code for this modules to get some inspiration on how to handle the different SOM variants.
