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:

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.
Andreas Färber attempted to upstream support for this SoC in 2017:

The struct mmp_clk_factor_tbl repeats the generic struct u32_fract.
Kill the custom one and use the generic one instead.

+description: |
+ The PXA1908 clock subsystem generates and supplies clock to various
+ controllers within the PXA1908 SoC. The PXA1908 contains numerous clock
+ controller blocks, with the ones currently supported being APBC, APBCP, MPMU
+ and APMU roughly corresponding to internal buses.
+
+ All these clock identifiers could be found in <include/dt-bindings/marvell,pxa1908.h>.
