Subject: powerpc/fsl-booke: Add p5020 DS board support
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=95400415c7b3f3dd43034c6c860897ac397ebe1b;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

powerpc/fsl-booke: Add p5020 DS board support

The P5020DS is in the same family of boards as the P4080 DS and thus
shares the corenet_ds code.
