I'll resend it later.

GUCTL1 reg has some useful functions which can be written by user. For rockchip platform, we set GUCTL1.DEV_FORCE_20_CLK_FOR_30_CLK (bit26, applicable for the core is programmed to operate in 2.0 device only) to 1 in bootrom, and after start the kernel, we want to check whether this bit can be reset to default 0 after the core reset. Dump GUCTL1 reg from debugfs is more convenient for us.
