Dear forum
I'm checking the TRM of GIC-700 Generic Interrupt Controller and refer to corresponding codes in TF-A.
In there, chip registers 'GICD_CHIPR<n>' seems that it specifies the range of SPI(SPI_BLOCK_MIN ~ SPI_BLOCKS) that the chip owns and specifies the address of chip?
Is the role of these register to just distinguish the SPI IDs which chip owns?
and then does these register be referred for distinguish which chip own occurred SPI?
Eventually, should it route SPI by using GICD_IROUTER to target chip?
Best Regards
