Noob here - be gentle :)

I=92ve got a couple Pogoplug V4 boxes that have Kirkwood 88F6192 (A1 =
variant) chip which is similar to 88F6281 except it is 800Mhz with =
166Mhz TCLK.

Using 10.1 the timekeeping is slow which I believe is because it thinks =
this is a 6281/200Mhz.

I=92m running a modified u-boot with this curious comment: =
u-boot-kirkwood/cpu.c at 2014.07.c-kirkwood =B7 mibodhi/u-boot-kirkwood. =
Indeed in freebsd, soc_id() is getting 0x6281 and reports:

	SOC: Marvell 88F6281 rev A1, TClock 200MHz

The chip manual says the PCIE vendor id register is read only and should =
give 0x6192 so I=92m confused.

I created a conf based on DOCKSTAR and a .dts based on db88f6281.dts so =
that pcie is available. With pcie I have the USB 3 ports working and =
even wifi. Nice tiny box if only it could keep time!
