The GIC-400 Interrupt controller has allocation of priority bits for secure and non-secure modes. It needs to be set in Secure monitor mode. By default, non-secure mode had zero bits. Once I allocated maximum bits for non-secure mode, interrupt started coming.
UART and Clock control registers not visible in non-secure mode
By default the clock is enabled for UART. So, clock was not an issue. But, the module needs to be enabled to read/write in secure/non-secure modes. This was default enabled in secure mode, but not for non-secure. So, once enabled the bits, it was visible to the program.
