Fix casting warning to pointer from integer of different size when enabling ARM64 support
What sort of error did you observe ?
The warning is triggered as ARM64 has build flag -Wpointer-to-int-cast and similar. Here is the build error log
arch/arm/mach-socfpga/system_manager.c: In function sysmgr_pinmux_init:
arch/arm/mach-socfpga/system_manager.c:59:18: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] uint32_t regs = (uint32_t)&sysmgr_regs ->emacio[0]; ^
