When using ARMv8 with ARMV8_SPIN_TABLE=y, we want the slave cores to wait on spin_table_cpu_release_addr, until the Linux kernel will "wake" them by writing to that location. The address of spin_table_cpu_release_addr is transferred to the kernel using the device tree that is updated by spin_table_update_dt(). However, if we also use SPL, then the slave cores are stuck at CPU_RELEASE_ADDR instead and as a result, never wake up. This patch releases the slave cores by writing spl_image->entry_point to CPU_RELEASE_ADDR location before the end of the SPL code (at jump_to_image_no_args()). That way, the slave cores will start to execute the u-boot and will get to the spin-table code and wait on the correct address (spin_table_cpu_release_addr).
