	  This choice selects peer-to-peer ("P2P"), or "peer delay"
	  PTP protocol. If activated, but P2P and E2E (end to end)
	  are built, and they can be chosen at run time, with P2P preset.
	  If you deny this option, P2P code is not built, to save some
	  binary size.

config IP
	depends on WR_NODE
	boolean "Compile minimal IP support in wrpc-sw"
	help
	  This allows to run LM32 code that is aware of IP. The feature is
	  needed to run Etherbone in your gateware, because Etherbone
	  is UDP-based and thus the CPU needs to run DHCP.

config CMD_CONFIG
	depends on WR_NODE
	boolean "Include configuration in the output binary"
	help
	  This options adds the "config" command to the shell, which

config PUTS_SYSLOG
	depends on SYSLOG
	boolean "Sent puts (i.e. printf) to syslog too"
	help
	  This allows logging the various warning and error messages
	  that normally go to the console alone, where nobody is looking
	  in a deployed system.  Output from interactive commands is
	  not sent to syslog, but self-timed diagnostic (stat, gui, verbose)
	  will reach syslog anyways, if an interactive user enables them.
	  Unfortunately, "stat" will reach syslog as several short strings,
	  and "gui" is full of escape sequences.

	boolean "Use SDB to manage storage (instead of legacy eeprom code)"
	help
	  Use SDB to manage flash and eeproms (both W1 and I2C). If not, legacy code
	  (eeprom only) will be selected.

config GENSDBFS

	depends on WR_NODE
	boolean "Write of WRPC diagnostics to dedicated WB registers"
	default n
	help
	  This is a software part of new (additional) diagnostics for WR PTP
	  Core. It allows to access diagnostics values through WB registers
	  (e.g. PCI bus). It allows the host machine (of SPEC/SVEC/etc.) to
	  easily access information about the health of WR PTP Core.

	  Please note that other option to access the status of WRPC, which
	  is direct access to the WRPC's memory does not provide any mechanism
	  to ensure the data consistency.

config WR_NODE_SIM
	depends on WR_NODE && !HOST_PROCESS
	boolean "Build simple software for test of WR PTP Core in simulation"
	default n
	help
	  This option builds binary that is meant to be used in testbench
	  simulations. It initializes only simulation-needed essentials.
	  All the initialization that is time-consuming and unnecessary
	  is avoided. The main function sends min-size frames to PTP
	  MAC address destination and expects the simulation to return
	  these frames.

config ABSCAL
  depends on WR_NODE
	default y
	boolean "Support absolute calibration"
	help
	  If you select this, you'll be able to do absolute calibration

config DEVELOPER
	depends on WR_NODE
	bool "Advanced configurations, only for developers"
	help
	  The following options are new features under testing, or
	  special customizations not normally useful for people not
	  directly working on this package.  Please don't use unless
	  you are a developer of wrpc-sw.

config PPSI_FORCE_CONFIG
	depends on DEVELOPER
	bool "Reconfigure ppsi from wrpc-sw at every build"
	default y
	help
	  If you are playing with custom ppsi configurations, please
	  disable this. Otherwise the option allows wrpc-sw to always
	  reconfigura ppsi, so if you change from end-to-end to
	  peer-to-peer here, the change is propagated to the ppsi build.

config HOST_PROCESS
	depends on DEVELOPER
	boolean "Build as a host process, to develop/debug network"

config RAMSIZE
	depends on DEVELOPER && LM32
	int "Size of the RAM in the FPGA for this program"
	default 90112
	help
	  The usual configuration for wrpc-sw is 0x16000 bytes
	  (i.e. 88kB = 90112 bytes) but if your project has less or
	  more features you may want to adjust the FPGA size and
	  choose your preferred value here.

config STACKSIZE
	depends on DEVELOPER && LM32
	int "Size of the stack area needed by this program"
	default 2048
	help
	  The linker complains if the code doesn't fit into RAM, but
	  we must also consider the stack, or the program will crash
	  at run time. (However, we have a detector for overflows).

config PRINT_BUFSIZE
	depends on DEVELOPER
	int "Size for the temporary output string of pp_printf"
	default 128
	help
	  This buffer is constant storage (i.e. wasted space), but it
	  also constraints the maximum lenght of text that can be written
	  in a single call to printf.

config TEMP_POLL_INTERVAL
	depends on DEVELOPER
	int "Poll interval, in seconds, for temperature sensors"

config TEMP_HIGH_THRESHOLD
	depends on DEVELOPER && SYSLOG

	int "Remember over-temperature every that many seconds"

config CMD_LL
	depends on DEVELOPER && LM32
	bool "Build low-level commands for development/testing"
	help
	  This enables low-level commands: "devmem" to read/write memory
	  and "delays" to read/write the constant delays in this device.
	  Please note that the delays have no immediate effect when set
	  on the master, because they are just sent to the slave
	  during the initial handshake

config DAC_LOG
	depends on DEVELOPER && EMBEDDED_NODE
	bool "Be able send DAC values through UDP"
	help
	  If you want to see the dac output, input to the VCXO main
	  oscillator, enable this. You'll have a "daclog" shell command
	  to set ipaddress and mac of the target host. UDP port is 1050.

config FLASH_INIT
	depends on DEVELOPER && LM32
	default y
	boolean "Read init commands from flash storage"

# CHECK_RESET for switch and node
config CHECK_RESET
	depends on DEVELOPER && LM32 || WR_SWITCH
	bool "Print a stack trace if reset happens"
	help
	  If the CPU is following a NULL pointer, the program will
	  be restarted. If this option is activated, the main function
	  detects that it is re-executed and dumps a stack trace; it
	  then clears the stack (for next time) and restarts again.

config SPLL_FIFO_LOG
	depends on DEVELOPER && LM32
	bool "Add a circular buffer for spll logging, used by tools/wrpc-dump"
	help
	  This option addrs 256 bytes to the wrpc bynary, to log
	  the DDMTD tags read from the fifos, the interrupts and the
	  related timing.  The information is shown by tools/wrpc-dump
	  if present, no change/rebuild of the tool is needed.

choice
	prompt "Implementation of pp_printf"
	depends on DEVELOPER

config PRINTF_IS_XINT
	bool "hex-and-int"
	help
	  This selects a printf that can only print decimal and hex
	  numbers, without obeying the format modifiers. %c and %s are
	  supported too, and %p is equivalent to %x.
	  See pp_printf/README for details.

config PRINTF_IS_FULL
	bool "full"
	help
	  This selects an implementation that supports all standard
	  formats with modifiers, like "%08X" and "%.5s". It costs
	  around 2k of compiled code more than XINT.
	  See pp_printf/README for details.

config PRINTF_IS_MINI
	bool "minimal"
	help
	  This selects a printf that prints all integers as hex,
	  without obeying the format modifiers. %c and %s are
	  supported too. See pp_printf/README for details.
	  This is not probably what you want for wrpc-sw.

config PRINTF_IS_NONE
	bool "empty"
	help
	  This selects a printf that prints the format string
	  alone and ignores all further arguments. Minimal size,
	  but not suited for wrpc-sw. See pp_printf/README for details.

config ASSERT
	bool "Build assertion checks in the code"
	depends on DEVELOPER
	default y
	help
	  Build assertions in the code, to catch unexpected situations.
	  When an assertion fails the code loops over repeating the
	  error message every second. OTOH, panic() is always built,
	  with no Kconfig -- and it does the same, unconditionally.

config DETERMINISTIC_BINARY
	depends on DEVELOPER || WR_SWITCH
	boolean "Build a binary that is the same every time"
	help
	  This option is used to #ifdef __DATE__ and __TIME__ strings
	  out of the compiled WRC binary. If you set it you'll get the
	  same binary bit-by-bit at each rebuild.  I am using this
	  option to hack the build procedure and use a simple "diff"
	  between the old and new output to verify I didn't introduce
	  changes.

	  If in doubt, say No.

config NET_VERBOSE
	depends on DEVELOPER

	  This is mainly a debug tool, to be left off unless you hack
	  in the network subsystem.

config PLL_VERBOSE
	depends on DEVELOPER
	boolean "Verbose messages in softpll"
	help
	  The softpll is usually silent in WR node and verbose in WR
	  switch. You can enable pll messages in WR node for debugging.

config PFILTER_VERBOSE
	depends on DEVELOPER
	boolean "Verbose messages in packet filter setup"
	help
	  A debug tool for people changing the packet filter rules

config WRC_VERBOSE

	help
	  This enables some more diagnostic messages. Normally off.

config FAKE_TEMPERATURES
	depends on DEVELOPER
	boolean "Offer an array of 3 fake temperatures, for testing"
	help
	  The option adds also a "faketemp" command, used to set
	  the fake temperatures: e.g. "faketemp 120 -10 50"

config LATENCY_PROBE
	depends on DEVELOPER
	bool "Build the latency probe mechanism (send/recv)"
	help
	  The latency prober sends two frames to broadcast and
	  then the timestamp of their departure time. The receiver
	  measures the network latency and reports it.

	  If this option is set, the receiver is always running. The
	  sender is built but must be activated by the latency shell cmd.

config LATENCY_ETHTYPE
	depends on LATENCY_PROBE
	int "Ethtype to use for latency probing"
	default 291
	help
	  Ethertypes 0x0101-0x01ff are marked as "experimental", apparently.

          an execution time will be printed to the console. Additionally,
          setting this value triggers printing messages if particular task
          runs longer than ever before. Setting to 0 disabled this
