From: "hongbo.wang" <[email protected]>
Add device tree demo for running Linux as an inmate on
NXP ls1043a RDB board.
GIC base address of Rev1.1 are different with Rev1.0, default dts is for
ls1043a RDB Rev1.1, if want to run linux-demo on Rev1.0, should change
to the following:
gic: interrupt-controller@1400000 {
compatible = "arm,gic-400";
#interrupt-cells = <3>;
interrupt-controller;
reg = <0x0 0x1401000 0 0x1000>, /* GICD */
<0x0 0x1402000 0 0x2000>, /* GICC */
<0x0 0x1404000 0 0x2000>, /* GICH */
<0x0 0x1406000 0 0x2000>; /* GICV */
interrupts = <1 9 0xf08>;
};
