The way the current CPM binding describes available multi-user (a.k.a. dual-ported) RAM doesn't work well when there are multiple free regions, and it doesn't work at all if the region doesn't begin at the start of the muram area (as the hardware needs to be programmed with offsets into this area). The latter situation can happen with SMC UARTs on CPM2, as its parameter RAM is relocatable, u-boot puts it at zero, and the kernel doesn't support moving it. It is now described with a muram node, similar to QE. The current CPM binding is sufficiently recent (i.e. never appeared in an official release) that compatibility with existing device trees is not an issue. The code supporting the new binding is shared between cpm1 and cpm2, rather than remain separated. QE should be able to use this code as well, once minor fixes are made to its device trees.
