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];
^
In file
included from arch/arm/mach-socfpga/system_manager.c:8:0:
./arch/arm/include/asm/io.h:78:29: warning: cast to pointer from
integer of different size [-Wint-to-pointer-cast]
#define __arch_putl(v,a) (*(volatile unsigned int
*)(a) = (v))
^
