Re: [U-Boot] [PATCH 4/4] ARM: LS1021A: to allow non-secure R/W access for all devices' mapped region

• reg = in_be32(csu_csl2);
• out_be32(csu_csl2, reg | CSU_CSL2x_NS_SUP_READ_ACCESS |

• CSU_CSL2x_NS_USER_READ_ACCESS);
  

+void enable_devices_ns_access(void)

This function is identical for twr and qds? Can't be just one in a common file?

Sure, I will follow your advice.

Thanks,
