Hello, This series adds initial support for the Marvell PXA1908 SoC and "samsung,coreprimevelte", a smartphone using the SoC. USB works and the phone can boot a rootfs from an SD card, but there are some warnings in the dmesg: During SMP initialization: [ 0.006519] CPU features: SANITY CHECK: Unexpected variation in SYS_CNTFRQ_EL0. Boot CPU: 0x000000018cba80, CPU1: 0x00000000000000 [ 0.006542] CPU features: Unsupported CPU feature variation detected.

A 3.14 based Marvell tree is available on GitHub acorn-marvell/brillo_pxa_kernel, and a Samsung one on GitHub CoderCharmander/g361f-kernel. Andreas Färber attempted to upstream support for this SoC in 2017: https://lore.kernel.org/lkml/20170222022929.10540-1-afaerber@xxxxxxx/ Signed-off-by: Duje Mihanović <duje.mihanovic@xxxxxxxx> Changes in v13: -
