+config PREP_RESIDUAL
+ bool "Support for PReP Residual Data"
+ depends on PPC_PREP
+ help
+ Some PReP systems have residual data passed to the kernel by the
+ firmware. This allows detection of memory size, devices present and
+ other useful pieces of information. Sometimes this information is
+ not present or incorrect, in which case it could lead to the machine
+ behaving incorrectly. If this happens, either disable PREP_RESIDUAL
+ or pass the 'noresidual' option to the kernel.
+
+ If you are running a PReP system, say Y here, otherwise say N.
+
+config PROC_PREPRESIDUAL
+ bool "Support for reading of PReP Residual Data in /proc"
+ depends on PREP_RESIDUAL && PROC_FS
+ help
+ Enabling this option will create a /proc/residual file which allows
+ you to get at the residual data on PReP systems. You will need a tool
+ (lsresidual) to parse it. If you aren't on a PReP system, you don't
+ want this.
