This is minimal infrastructure needed for devicetree work. It uses an a sample "skeleton" devicetree - embedded in kernel image - to print the board, manufacturer by parsing the top-level "compatible" string. As of now we don't need any additional "board" specific "machine_desc".

Includes following fixes courtesy review by Al-Viro * Tracer poke to Callee-regs were lost Before going off into do_signal( ) we save the user-mode callee regs (as they are not saved by default as part of pt_regs). This is to make sure that that a Tracer (if tracing related signal) is able to do likes of PEEKUSR(callee-reg). However in return path we were simply discarding the user-mode callee regs, which would break a POKEUSR(callee-reg) from a tracer. * Issue related to multiple syscall restarts are addressed in next patch Signed-off-by: NVineet Gupta <vgupta@synopsys.com> Cc: Al Viro <viro@ZenIV.linux.org.uk> Acked-by: NJonas Bonn <jonas@southpole.se>

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.
