AM64 Phycore SoM has a S28 64 MiB OSPI flash with sector size of 256 KiB thus the size of the smallest partition is chosen as 256 KiB, the partition names and offsets are chosen according to the corresponding name and offsets in bootloader Signed-off-by: Vaishnav Achath --- .../boot/dts/ti/k3-am64-phycore-som.dtsi | 41 +++++++++++++++++++ 1 file changed, 41 insertions(+) diff --git a/arch/arm64/boot/dts/ti/k3-am64-phycore-som.dtsi b/arch/arm64/b= oot/dts/ti/k3-am64-phycore-som.dtsi index 8dfb6301b17d..0d3d785530cf 100644 --- a/arch/arm64/boot/dts/ti/k3-am64-phycore-som.dtsi +++ b/arch/arm64/boot/dts/ti/k3-am64-phycore-som.dtsi @@ -219,6 +219,47 @@ cdns,tchsh-ns =3D <60>; cdns,tslch-ns =3D <60>; cdns,read-delay =3D <0>; + + partitions { + compatible =3D "fixed-partitions"; + #address-cells =3D <1>; + #size-cells =3D <1>; + + partition@0 { + label =3D "ospi.tiboot3"; + reg =3D <0x0 0x100000>; + }; + + partition@100000 { + label =3D "ospi.tispl"; + reg =3D <0x100000 0x200000>; + }; + + partition@300000 { + label =3D "ospi.u-boot"; + reg =3D <0x300000 0x400000>; + }; + + partition@700000 { + label =3D "ospi.env"; + reg =3D <0x700000 0x40000>; + }; + + partition@740000 { + label =3D "ospi.env.backup"; + reg =3D <0x740000 0x40000>; + }; + + partition@800000 { + label =3D "ospi.rootfs"; + reg =3D <0x800000 0x37c0000>; + }; + + partition@3fc0000 { + label =3D "ospi.phypattern"; + reg =3D <0x3fc0000 0x40000>; + }; + }; }; }; =20 --=20 2.17.1
