Hello Team,

In arch/Kconfig, for Renesas architecture, the configuration ARCH_NOINTC is 
selected as mentioned below :

config ARCH_RENESAS
bool "Renesas"
select ARCH_NOINTC
select ARCH_HAVE_INTERRUPTSTACK
---help---
Renesas architectures (SH and M16C).

Renesas RX65N supports Interrupt controller unit(ICU) and hence ARCH_NOINTC 
configuration should be disabled.

Since it is enabled at the top, we are unable to change the configuration for 
ARCH_NOINTC .

Can we modify this Kconfig to remove "select ARCH_NOINTC" ?

Since this configuration is disabled at the top level, the function 
declarations up_enable_irq() and up_disable_irq() are excluded from the 
compilation.

This results in "implicit declaration" warning for RX65N


Regards,

Anjana
