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.

On Samsung's PXA1908 phones, the bootloader does not start the ARM system timer, and my temporary solution (which isn't present in this series) was to put the code for starting the timer in the clock driver. Would this hack be accepted upstream in the form of a platform or clocksource driver such as drivers/clocksource/timer-mediatek-cpux.c? A 3.14 based Marvell tree is available on GitHub acorn-marvell/brillo_pxa_kernel, and a Samsung one on GitHub CoderCharmander/g361f-kernel.
