Valentine Barshak	340ffd267c	[POWERPC] 4xx: 440EPx/GRx incorrect write to DDR SDRAM errata workaround ... Add a workaround for PowerPC 440EPx/GRx incorrect write to DDR SDRAM errata. Data can be written to wrong address in SDRAM when write pipelining enabled on plb0. We disable it in the cpu_setup for these processors at early init.

Valentine Barshak	8112753bb2	[POWERPC] 4xx: Move 440EP(x) FPU setup from head_44x to cpu_setup_4xx ... The PowerPC 440EP(x) FPU init is currently done in head_44x under ifdefs. Since we should support more then one board in the same kernel, we move FPU initialization code from head_44x to cpu_setup_44x and add cpu_setup callbacks for 440EP(x).

Valentine Barshak	84e3ad5b91	[POWERPC] 4xx: Introduce cpu_setup functionality to 44x platform ... This adds cpu_setup functionality for ppc44x platform. Low level cpu-spefic initialization routines should be placed in cpu_setup_44x.S and a callback should be added to cputable. The cpu_setup is invoked by identify_cpu() function at early init.
