Cover letter [PATCH 0/5] ARM: DT: remove redundant DT related code

Hi,

As part of my changes to remove duplicate code for parsing cpu nodes in the device tree, I found few unnecessary code mostly around smp_init_cpus. Most of the ARM Cortex A9 based platforms use SCU to get the number of cpus while many others depend on the device tree.

Even on DT based platforms using SCU, they can be made to depend on DT to cpu count simplifying smp_init_cpus. In fact arm_dt_init_cpu_maps called before smp_init_cpus, already does the device tree parsing, validating nr_cpu_ids and setting the cpu_possible_mask appropriately.

However this series targets only the platforms using DT for cpu count (i.e. not using SCU)

Sudeep
