[PATCH 0/7] ARM: hisi: enable HiP01 SoC

[Wang Long]

Hi, Xu Wei

This series patch enable Hisilicon HiP01 SoC. The HiP01 SoC series
chip is designed for networking product, it integrates a rich peripheral
interfaces to support network applications and supports both one 
core or dual cores and quad cores. The core is Cortex A9. 

This series patch rebased on Linux 3.19-rc1.

Best Regards

[PATCH 5/7] ARM: hisi: add a common smp_prepares_cpus function

[Wang Long]

As hix5hd2 and hip01 has the same .smp_prepare_cpus
in struct smp_operations, so rename hix5hd2_smp_prepare_cpus
to hisi_common_smp_prepare_cpus.

the hip01 will use hisi_common_smp_prepare_cpus in its
struct smp_operations.

As hix5hd2 and hip01 has the same secondary_startup

the hip01 will use hisi_secondary_startup for the
secondary core boot.
