So far it's always a u32 type of CCSR address. > > + priv->regs = (struct fsl_qspi_regs *)(unsigned long)plat->reg_base; > > How about (struct fsl_qspi_regs *)(uintptr_t)plat->reg_base? > > York > The size of ''unsigned long'' depends on compilers. It works well with GCC. Looks the same. But not sure what is defining CONFIG_USE_STDIN for. #ifdef CONFIG_USE_STDIN /* Provided by gcc. */ #include <stdint.h> #else /* Type for `void *' pointers. */ typedef unsigned long int uintptr_t; #endif Regards, Qianyu _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
