[POWERPC] ps3: repository storage support
Handle storage-related repository data: - Add missing implementations of ps3_repository_read_stor_*() repository accessors. - Dump storage properties in debug mode - Add PS3_DEV_TYPE_STOR_{DISK,ROM,FLASH} device types (which are identical to the corresponding SCSI device types) to enum ps3_dev_type Signed-off-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com> Signed-off-by: Geoff Levand <geoffrey.levand@am.sony.com> Acked-by: Arnd Bergmann <arnd.bergmann@de.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
