fsl,qman-fqd property missing on p5020 based board

[yoctoplanet]

I have a board based on the P5020 SoC. I get following boot log when I try to boot linux (Freescale SDK 1.9):

No /soc@ffe000000/qman@318000 property 'fsl,qman-fqd', using memblock_alloc(0000000000400000)

No /soc@ffe000000/qman@318000 property 'fsl,qman-pfdr', using memblock_alloc(0000000002000000)

Qman ver:0a01,01,02,00

No /soc@ffe000000/bman@31a000 property 'fsl,bman-fbpr', using memblock_alloc(0000000001000000)

Bman ver:0a02,01,00

pme: No /soc@ffe000000/pme@316000 property 'fsl,pme-pdsr', using memblock_alloc(0x0000000001000000)

pme: No /soc@ffe000000/pme@316000 property 'fsl,pme-sre', using memblock_alloc(0x0000000000a00000)

I have those nodes in my device tree, but the bootlog stays the same:

under / :

	reserved-memory {
	#address-cells = <2>;
	#size-cells = <2>;
	ranges;
	pme_pdsr: pme-pdsr {
		compatible = "fsl,pme-pdsr";
		alloc-ranges = <0 0 0x10 0>;
		size = <0 0x1000000>;
		alignment = <0 0x1000000>;
	};
	pme_sre: pme-sre {
		compatible = "fsl,pme-sre";
		alloc-ranges = <0 0 0x10 0>;
		size = <0 0xa00000>;
		alignment = <0 0xa00000>;
	};
	qman_fqd: qman-fqd {
		compatible = "fsl,qman-fqd";
		alloc-ranges = <0 0 0x10 0>;
		size = <0 0x400000>;
		alignment = <0 0x400000>;
	};
	qman_pfdr: qman-pfdr {
		compatible = "fsl,qman-pfdr";
		alloc-ranges = <0 0 0x10 0>;
		size = <0 0x2000000>;
		alignment = <0 0x2000000>;
	};
	bman_fbpr: bman-fbpr {
		compatible = "fsl,bman-fbpr";
		alloc-ranges = <0 0 0x10 0>;
		size = <0 0x1000000>;
		alignment = <0 0x1000000>;
	};
};

under /soc: soc@ffe000000/fman@400000:

	pme@316000 {
		memory-region = <&pme_pdsr &pme_sre>;
	};
	qman@318000 {
		memory-region = <&qman_fqd &qman_pfdr>;
	};
	bman@31a000 {
		memory-region = <&bman_fbpr>;
	};

I verified SDK 1.9 pre-built images on P5020DS, also produced the above message during Linux Kernel booting.

This is because Linux Kernel parses the <name> property to extract the memory location and size and memblock_reserve() it. If it isn't supplied, memblock_alloc() the default size, so it doesn't affect the normal function.

If you want to use these property, please refer to the following device tree definition.

qman: qman@318000 {

compatible = "fsl,qman";

reg = <0x318000 0x1000>;

fsl,qman-fqd = <0x0 0x22000000 0x0 0x00200000>;

fsl,qman-pfdr = <0x0 0x21000000 0x0 0x01000000>;

fsl,liodn = <0x1f>;

};

bman: bman@31a000 {

compatible = "fsl,bman";

reg = <0x31a000 0x1000>;

interrupts = <16 2 1 3>;

/* Same as fsl,qman-*, use default allocation */

/* fsl,bman-fbpr = <0x0 0x22000000 0x0 0x01000000>; */

};

pme: pme@316000 {

compatible = "fsl,p4080-pme", "fsl,pme";

reg = <0x316000 0x10000>;

fsl,pme-pdsr = <0x0 0x20000000 0x0 0x01000000>

fsl,pme-sre = <0x0 0x30000000 0x0 0x01000000>

};

Thank you for your answer!

This helped me and now it works.

Hint: You might edit your post as you forgot some semicolons.

Please add the following in your dts file.

/include/ "qoriq-pme-0.dtsi"

/include/ "qoriq-qman1.dtsi"

/include/ "qoriq-bman1.dtsi"

For details, please refer to arch/powerpc/boot/dts/fsl/p5020si-post.dtsi in Kernel source.

Have a great day,
