+comment "UBI debugging options"
+        depends on MTD_UBI
+
+config MTD_UBI_DEBUG
+        bool "UBI debugging"
+        depends on SYSFS
+        depends on MTD_UBI
+        select DEBUG_FS
+        select KALLSYMS_ALL
+        help
+          This option enables UBI debugging.
+
+config MTD_UBI_DEBUG_MSG
+        bool "UBI debugging messages"
+        depends on MTD_UBI_DEBUG
+        default n
+        help
+          This option enables UBI debugging messages.
+
+config MTD_UBI_DEBUG_PARANOID
+        bool "Extra self-checks"
+        default n
+        depends on MTD_UBI_DEBUG
+        help
+          This option enables extra checks in UBI code. Note this slows UBI down
+          significantly.
+
+config MTD_UBI_DEBUG_DISABLE_BGT
+        bool "Do not enable the UBI background thread"
+        depends on MTD_UBI_DEBUG
+        default n
+        help
+          This option switches the background thread off by default. The thread
+          may be also be enabled/disabled via UBI sysfs.
+
+config MTD_UBI_DEBUG_USERSPACE_IO
+        bool "Direct user-space write/erase support"
+        default n
+        depends on MTD_UBI_DEBUG
+        help
+          By default, users cannot directly write and erase individual
+          eraseblocks of dynamic volumes, and have to use update operation
+          instead. This option enables this capability - it is very useful for
+          debugging and testing.
+
+config MTD_UBI_DEBUG_EMULATE_BITFLIPS
+        bool "Emulate flash bit-flips"
+        depends on MTD_UBI_DEBUG
+        default n
+        help
+          This option emulates bit-flips with probability 1/50, which in turn
+          causes scrubbing. Useful for debugging and stressing UBI.
+
+config MTD_UBI_DEBUG_EMULATE_WRITE_FAILURES
+        bool "Emulate flash write failures"
+        depends on MTD_UBI_DEBUG
+        default n
+        help
+          This option emulates write failures with probability 1/100. Useful for
+          debugging and testing how UBI handlines errors.
+
+config MTD_UBI_DEBUG_EMULATE_ERASE_FAILURES
+        bool "Emulate flash erase failures"
+        depends on MTD_UBI_DEBUG
+        default n
+        help
+          This option emulates erase failures with probability 1/100. Useful for
+          debugging and testing how UBI handlines errors.
+
+menu "Additional UBI debugging messages"
+        depends on MTD_UBI_DEBUG
+
+config MTD_UBI_DEBUG_MSG_BLD
+        bool "Additional UBI initialization and build messages"
+        default n
+        depends on MTD_UBI_DEBUG
+        help
+          This option enables detailed UBI initialization and device build
+          debugging messages.
+
+config MTD_UBI_DEBUG_MSG_EBA
+        bool "Eraseblock association unit messages"
+        default n
+        depends on MTD_UBI_DEBUG
+        help
+          This option enables debugging messages from the UBI eraseblock
+          association unit.
+
+config MTD_UBI_DEBUG_MSG_WL
+        bool "Wear-leveling unit messages"
+        default n
+        depends on MTD_UBI_DEBUG
+        help
+          This option enables debugging messages from the UBI wear-leveling
+          unit.
+
+config MTD_UBI_DEBUG_MSG_IO
+        bool "Input/output unit messages"
+        default n
+        depends on MTD_UBI_DEBUG
+        help
+          This option enables debugging messages from the UBI input/output unit.
