Hi Quentin,

     For this board:

        aarch64:  w+   ringneck-px30
+  static struct px30_cru * const cru = (void *)CRU_BASE;
+                                 ^~~
+  static struct px30_grf * const grf = (void *)GRF_BASE;
w+arch/arm/mach-rockchip/px30/px30.c: In function ‘board_debug_uart_init’:
w+arch/arm/mach-rockchip/px30/px30.c:313:33: warning: unused variable 
‘cru’ [-Wunused-variable]
w+arch/arm/mach-rockchip/px30/px30.c:312:33: warning: unused variable 
‘grf’ [-Wunused-variable]
w+arch/arm/mach-rockchip/px30/px30.c:312:33: warning: ‘grf’ defined but 
not used [-Wunused-const-variable=]
w+arch/arm/mach-rockchip/px30/px30.c:313:33: warning: ‘cru’ defined but 
not used [-Wunused-const-variable=]

This will be treat as error on denx ci system.


Thanks,

- Kever
