It's a arm7tdmi SoC (GeneralPlus gpl32700 SoC).
The code is: current Linus' tree + patches for this SoC.
The patches for this SoC includes:
irqchip, clocksource, pinctrl, gpio, uart, spi, sd/mmc host drivers.
I also apply a out-of-tree sdio wifi driver for mt5931 wifi module.

I can successfully boot and running busybox if using ext2 as root.
Thus I don't hit "spin_unlock_irq decrement preempt_count failure" if using ext2 as root.
The storage is a spi nor flash, so I prefer to use jffs2 but then I got
the hangup.

BTW, I got below panic today:
