Probe the system parallel flash using device tree rather than platform

What's "pflash"? I'd suggest to just name the ndoe "flash@..." to be more in line with ePAPR.

+ compatible = "intel,28f128j3", "cfi-flash";
+ reg = <0x1c000000 0x2000000>;
+ #address-cells = <1>;
+ #size-cells = <1>;

+ user-fs@0 {

+ board-config@3e0000 {
+ label = "Board Config";
+ reg = <0x1fc0000 0x40000>;
+ };

Doesn't MTD code complain that the partitions are not subnodes of a "partitions" node?
It's the preferred way now...
