+config TRACE_IRQFLAGS_SUPPORT

+	default y
+
+source "lib/Kconfig.debug"
+
+config EARLY_PRINTK
+	bool "Early printk" if EXPERT
+	depends on SYS_HAS_EARLY_PRINTK
+	default y
+	help
+	  This option enables special console drivers which allow the kernel
+	  to print messages very early in the bootup process.
+
+	  This is useful for kernel debugging when your machine crashes very
+	  early before the console code is initialized. For normal operation,
+	  it is not recommended because it looks ugly on some machines and
+	  doesn't cooperate with an X server. You should normally say N here,
+	  unless you want to debug such a crash.
+
+config CMDLINE_BOOL
+	bool "Built-in kernel command line"
+	default n
+	help
+	  For most systems, it is firmware or second stage bootloader that
+	  by default specifies the kernel command line options.  However,
+	  it might be necessary or advantageous to either override the
+	  default kernel command line or add a few extra options to it.
+	  For such cases, this option allows you to hardcode your own
+	  command line options directly into the kernel.  For that, you
+	  should choose 'Y' here, and fill in the extra boot arguments
+	  in CONFIG_CMDLINE.
+
+	  The built-in options will be concatenated to the default command
+	  line if CMDLINE_OVERRIDE is set to 'N'. Otherwise, the default
+	  command line will be ignored and replaced by the built-in string.
+
+	  Most MIPS systems will normally expect 'N' here and rely upon
+	  the command line from the firmware or the second-stage bootloader.
+
+config CMDLINE
+	string "Default kernel command string"
+	depends on CMDLINE_BOOL
+	default ""
+	help
+	  On some platforms, there is currently no way for the boot loader to
+	  pass arguments to the kernel.  For these platforms, and for the cases
+	  when you want to add some extra options to the command line or ignore
+	  the default command line, you can supply some command-line options at
+	  build time by entering them here.  In other cases you can specify
+	  kernel args so that you don't have to set them up in board prom
+	  initialization routines.
+
+	  For more information, see the CMDLINE_BOOL and CMDLINE_OVERRIDE
+	  options.
+
+config CMDLINE_OVERRIDE
+	bool "Built-in command line overrides firware arguments"
+	default n
+	depends on CMDLINE_BOOL
+	help
+	  By setting this option to 'Y' you will have your kernel ignore
+	  command line arguments from firmware or second stage bootloader.
+	  Instead, the built-in command line will be used exclusively.
+
+	  Normally, you will choose 'N' here.
+
+config DEBUG_STACKOVERFLOW
+	bool "Check for stack overflows"
+	depends on DEBUG_KERNEL
+	help
+	  This option will cause messages to be printed if free stack space
+	  drops below a certain limit(2GB on MIPS). The debugging option
+	  provides another way to check stack overflow happened on kernel mode
+	  stack usually caused by nested interruption.
+
+config SMTC_IDLE_HOOK_DEBUG
+	bool "Enable additional debug checks before going into CPU idle loop"
+	depends on DEBUG_KERNEL && MIPS_MT_SMTC
+	help
+	  This option enables Enable additional debug checks before going into
+	  CPU idle loop.  For details on these checks, see
+	  arch/mips/kernel/smtc.c.  This debugging option result in significant
+	  overhead so should be disabled in production kernels.
+
+config SB1XXX_CORELIS
+	bool "Corelis Debugger"
+	depends on SIBYTE_SB1xxx_SOC
+	select DEBUG_INFO
+	help
+	  Select compile flags that produce code that can be processed by the
+	  Corelis mksym utility and UDB Emulator.
+
+config RUNTIME_DEBUG
+	bool "Enable run-time debugging"
+	depends on DEBUG_KERNEL
+	help
+	  If you say Y here, some debugging macros will do run-time checking.
+	  If you say N here, those macros will mostly turn to no-ops.  See
+	  arch/mips/include/asm/debug.h for debugging macros.
+	  If unsure, say N.
+
+config DEBUG_ZBOOT
+	bool "Enable compressed kernel support debugging"
+	depends on DEBUG_KERNEL && SYS_SUPPORTS_ZBOOT
+	default n
+	help
+	  If you want to add compressed kernel support to a new board, and the
+	  board supports uart16550 compatible serial port, please select
+	  SYS_SUPPORTS_ZBOOT_UART16550 for your board and enable this option to
+	  debug it.
+
+	  If your board doesn't support uart16550 compatible serial port, you
+	  can try to select SYS_SUPPORTS_ZBOOT and use the other methods to
+	  debug it. for example, add a new serial port support just as
+	  arch/mips/boot/compressed/uart-16550.c does.
+
+	  After the compressed kernel support works, please disable this option
+	  to reduce the kernel image size and speed up the booting procedure a
+	  little.
+
+config SPINLOCK_TEST
+	bool "Enable spinlock timing tests in debugfs"
+	depends on DEBUG_FS
+	default n
+	help
+	  Add several files to the debugfs to test spinlock speed.
