+
+With the current range specified for the CPU interface there is an
+error message at boot:
+
+GIC: GICv2 detected, but range too small and irqchip.gicv2_force_probe not set
+
+Setting irqchip.gicv2_force_probe=1 in bootargs results in:
+
+GIC: Aliased GICv2 at 0x0000000010320000, trying to find the canonical range over 128kB
+GIC: Adjusting CPU interface base to 0x000000001032f000
+GIC: Using split EOI/Deactivate mode
+
+Using the adjusted CPU interface base and 8K size results in only the
+final line remaining and fully working system as well as /proc/interrupts
+showing additional IPI3,4,5,6:
+
+IPI3: 0 0 CPU stop (for crash dump) interrupts
+IPI4: 0 0 Timer broadcast interrupts
+IPI5: 0 0 IRQ work interrupts
+IPI6: 0 0 CPU wake-up interrupts

+On an MT7622 system, the kernel complains of not being able to detect the cache
+hierarchy of CPU 0. Specify the shared L2 cache node in the device tree, in
+order to fix this.

+The MT7622 device tree never bothered to specify the number of virtual DMA
+channels for the HSDMA controller, always falling back to the default value of
+3. Make this value explicit, in order to avoid the following dmesg notification:

+mtk_hsdma 1b007000.dma-controller: Using 3 as missing dma-requests property
