Subject: Re: [PATCH 05/17] pseries: Enabled the PFO-based RNG accelerator


Hi,

+#if defined(CONFIG_HW_RANDOM_PSERIES) || \
+	defined(CONFIG_HW_RANDOM_PSERIES_MODULE)
+#define OV5_PFO_HW_RNG		0x80	/* PFO Random Number
Generator */ +#else
+#define OV5_PFO_HW_RNG		0x00
+#endif

Milton tipped me off about this. We really don't want to be doing
ibm,client-architecture reboots every time a config option is changed.

Let's just hardwire it on.

Anton
