Juan Castillo 53fdcebd6d Call platform_is_primary_cpu() only from reset handler The purpose of platform_is_primary_cpu() is to determine after reset (BL1 or BL3-1 with reset handler) if the current CPU must follow the cold boot path (primary CPU), or wait in a safe state (secondary CPU) until the primary CPU has finished the system initialization. This patch removes redundant calls to platform_is_primary_cpu() in subsequent bootloader entrypoints since the reset handler already guarantees that code is executed exclusively on the primary CPU. Additionally, this patch removes the weak definition of platform_is_primary_cpu(), so the implementation of this function becomes mandatory. Removing the weak symbol avoids other bootloaders accidentally picking up an invalid definition in case the porting layer makes the real function available only to BL1. The define PRIMARY_CPU is no longer mandatory in the platform porting because platform_is_primary_cpu() hides the implementation details (for instance, there may be platforms that report the primary CPU in a system register). The primary CPU definition in FVP has been moved to fvp_def.h. The porting guide has been updated accordingly.
