2config PREP_RESIDUAL
3 bool "Support for PReP Residual Data"
4 depends on PPC_PREP
5 help
6 Some PReP systems have residual data passed to the kernel by the
7 firmware. This allows detection of memory size, devices present and
8 other useful pieces of information. Sometimes this information is
9 not present or incorrect, in which case it could lead to the machine
10 behaving incorrectly. If this happens, either disable PREP_RESIDUAL
11 or pass the 'noresidual' option to the kernel.

13 If you are running a PReP system, say Y here, otherwise say N.

15config PROC_PREPRESIDUAL
16 bool "Support for reading of PReP Residual Data in /proc"
17 depends on PREP_RESIDUAL && PROC_FS
18 help
19 Enabling this option will create a /proc/residual file which allows
20 you to get at the residual data on PReP systems. You will need a tool
21 (lsresidual) to parse it. If you aren't on a PReP system, you don't
22 want this.
