IRQ routing path of Loongson-3:
Devices(most) --> I8259 --> HT Controller --> IRQ Routing Table --> CPU
^
|
Device(legacy devices such as UART) --> Bonito ---|
IRQ Routing Table route 32 INTs to CPU's INT0~INT3(IP2~IP5 of CP0), 32
INTs include 16 HT INTs(mostly), 4 PCI INTs, 1 LPC INT, etc. IP6 is used
for IPI and IP7 is used for internal MIPS timer. LOONGSON_INT_ROUTER_*
are IRQ Routing Table registers.
I8259 IRQs are 1:1 mapped to HT1 INTs. LOONGSON_HT1_* are configuration
registers of HT1 controller.
