Review comment:
Renesas RX65N supports Group Interrupts. Each Group Interrupt groups
“unrelated” events from multiple peripherals. So segregating these events into
respective peripheral drivers at the do_irq level complicates the
implementation. And also in order to maintain trampoline style of
implementation, ‘multi_switching’ assembly macro was implemented. With this
implementation, single interrupt is expanded into multiple vector numbers and
rest of the interrupt handling mechanism are maintained as is. Please let us
know your comments.
