config MISSING_BOARD_RESET
	bool
	help
	  Selected by boards that don't provide a do_board_reset()
	  implementation. This activates a stub that logs the missing
	  board reset and halts execution.

config RAMSTAGE_ADA
	bool
	help
	  Selected by features that use Ada code in ramstage.

config RAMSTAGE_LIBHWBASE
	bool
	select RAMSTAGE_ADA
	help
	  Selected by features that require `libhwbase` in ramstage.

config FLATTENED_DEVICE_TREE
	bool
	help
	  Selected by features that require to parse and manipulate a flattened
	  devicetree in ramstage.

config HAVE_SPD_IN_CBFS
	bool
	help
	  If enabled, add support for adding spd.hex files in cbfs as spd.bin
	  and locating it runtime to load SPD.

config DIMM_MAX
	int
	default 4
	help
	  Total number of memory DIMM slots available on motherboard.
	  It is multiplication of number of channel to number of DIMMs per
	  channel

config DIMM_SPD_SIZE
	int
	default 256
	help
	  Total SPD size that will be used for DIMM.
	  Ex: DDR3 256, DDR4 512.

config SPD_READ_BY_WORD
	bool

config SPD_CACHE_IN_FMAP
	bool
	default n
	help
	  Enables capability to cache DIMM SPDs in a dedicated FMAP region
	  to speed loading of SPD data. Currently requires board-level
	  romstage implementation to read/write/utilize cached SPD data.
	  When the default FMAP is used, will create a region named RW_SPD_CACHE
	  to store the cached SPD data.

config SPD_CACHE_FMAP_NAME
	string
	depends on SPD_CACHE_IN_FMAP
	default "RW_SPD_CACHE"
	help
	  Name of the FMAP region created in the default FMAP to cache SPD data.

config HWBASE_DYNAMIC_MMIO
	def_bool y

config HWBASE_DEFAULT_MMCONF
	hex
	default ECAM_MMCONF_BASE_ADDRESS

config HWBASE_DIRECT_PCIDEV
	def_bool y

endif

config NO_FMAP_CACHE
	bool
	help
	  If your platform really doesn't want to use an FMAP cache (e.g. due to
	  space constraints), you can select this to disable warnings and save
	  a bit more code.

config ESPI_DEBUG
	bool
	help
	  This option enables eSPI library helper functions for displaying debug
	  information.

config NO_CBFS_MCACHE
	bool
	help
	  Disables the CBFS metadata cache. This means that your platform does
	  not need to provide a CBFS_MCACHE section in memlayout and can save
	  the associated CAR/SRAM size. In that case every single CBFS file
	  lookup must re-read the same CBFS directory entries from flash to find
	  the respective file.

config CBFS_CACHE_ALIGN
	int
	default 8
	help
	  Sets the alignment of the buffers returned by the cbfs_cache.

config CBFS_PRELOAD
	bool
	depends on COOP_MULTITASKING
	help
	  When enabled it will be possible to preload CBFS files into the
	  cbfs_cache. This helps reduce boot time by loading the files
	  in the background before they are actually required. This feature
	  depends on the read-only boot_device having a DMA controller to
	  perform the background transfer.

config PAYLOAD_PRELOAD
	bool
	depends on COOP_MULTITASKING
	help
	  On some systems with SPI DMA controllers, it is possible to preload
	  the payload while ramstage is executing. This can be selected by the
	  SoC to enable payload preloading.

	  The SoC needs to define a payload_preload_cache region where the
	  raw payload can be placed.
