Arnd in his review pointed out that arch Kconfig organisation has several deficiencies: * Build time entries for things which can be runtime extracted from DT (e.g. SDRAM size, core clk frequency..) * Not multi-platform-image-build friendly (choice .. endchoice constructs) * cpu variants support (750/770) is exclusive. The first 2 have been fixed in subsequent patches. Due to the nature of the 750 and 770, it is not possible to build for both together, w/o special runtime glue code which would hurt performance.
