Currently the kernel provides the contents of p-series NVRAM only as a
simple stream of bytes via /dev/nvram, which must be interpreted in user
space by the nvram command in the powerpc-utils package. This patch set
exploits the pstore subsystem to expose each partition in NVRAM as a
separate file in /dev/pstore. For instance Oops messages will stored in a
file named [dmesg-nvram-2].
