## SPDX-License-Identifier: GPL-2.0-only 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 ROMSTAGE_ADA bool help Selected by features that use Ada code in romstage. 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 ROMSTAGE_LIBHWBASE bool select ROMSTAGE_ADA help Selected by features that require `libhwbase` in romstage. 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 MAX_SOCKET int default 1 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. if RAMSTAGE_LIBHWBASE && !ROMSTAGE_LIBHWBASE config HWBASE_DYNAMIC_MMIO def_bool y endif if ROMSTAGE_LIBHWBASE config HWBASE_STATIC_MMIO def_bool y endif if RAMSTAGE_LIBHWBASE || ROMSTAGE_LIBHWBASE 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 DECOMPRESS_OFAST bool depends on COMPILER_GCC default y help Compile the decompressing function in -Ofast instead of standard -Os config PROBE_RAM def_bool y if VENDOR_EMULATION help When enabled it will be possible to detect usable RAM using probe_ram function. menu "Boot Logo Configuration" config BMP_LOGO bool "Enable logo" default n help Uses the FSP to display the boot logo. This method supports a BMP file only. The uncompressed size can be up to 1 MB. The logo can be compressed based on either `BMP_LOGO_COMPRESS_*` configs (default LZMA). config HAVE_CUSTOM_BMP_LOGO def_bool n depends on BMP_LOGO config HAVE_BMP_LOGO_COMPRESS_LZMA bool depends on BMP_LOGO default y choice prompt "BMP Logo compression" depends on BMP_LOGO default BMP_LOGO_COMPRESS_LZMA if HAVE_BMP_LOGO_COMPRESS_LZMA default BMP_LOGO_COMPRESS_LZ4 config BMP_LOGO_COMPRESS_LZMA bool "Use LZMA compression for BMP logo" help This option enables the use of LZMA compression for the BMP logo. LZMA is a lossless compression algorithm that can significantly reduce the size of the logo, without sacrificing quality. If this option is not enabled, the BMP logo will be uncompressed. config BMP_LOGO_COMPRESS_LZ4 bool "Compress BMP logo using LZ4" help This option enables compression of the BMP logo using the LZ4 algorithm. Although the size reduction is not as efficient as LZMA compression, however, it can also make the boot process slightly faster compared to the LZMA. endchoice config BMP_LOGO_FILE_NAME string "Logo file" depends on BMP_LOGO default "3rdparty/blobs/mainboard/\$(MAINBOARDDIR)/logo.bmp" config HAVE_ESOL_SUPPORT_FOR_LOW_BATTERY_INDICATOR bool depends on FSP_UGOP_EARLY_SIGN_OF_LIFE || MAINBOARD_HAS_EARLY_LIBGFXINIT help Enable low-battery indicator support in eSOL. This option should be selected if the eSOL feature (using either libgfxinit or FSP uGOP) supports displaying a low-battery indicator. Platforms selecting `MAINBOARD_HAS_EARLY_LIBGFXINIT` can default enable this option. For platforms using FSP uGOP, this option should only be enabled if uGOP has implemented the necessary low-battery handling. This allows platforms to control low-battery indicator support based on uGOP readiness. config PLATFORM_HAS_LOW_BATTERY_INDICATOR bool "Display low battery indicator" depends on BMP_LOGO help If enabled, this option displays a low battery indicator screen. This screen can be used to warn the user that the battery is low and that they should plug in the device. This option requires that the system have a display and that the BMP_LOGO option is enabled. if PLATFORM_HAS_LOW_BATTERY_INDICATOR config PLATFORM_LOW_BATTERY_SHUTDOWN_DELAY_SEC int default 5 help Delay, in seconds, before system shutdown due to low battery. This delay allows the user to observe the low-battery indicator. The default value of 5 seconds aligns with standard user experience (UX) practices. Platforms may override this value based on specific product requirements. config PLATFORM_HAS_EARLY_LOW_BATTERY_INDICATOR bool "Display low battery indicator in romstage" depends on HAVE_ESOL_SUPPORT_FOR_LOW_BATTERY_INDICATOR help If enabled, this option displays a low battery indicator during romstage (before memory is available) in text mode in the firmware and defer the firmware update. This screen can be used to warn the user that the battery is low and that they should plug in the device. config PLATFORM_LOW_BATTERY_INDICATOR_LOGO_PATH string "Path to low battery logo file" default "3rdparty/blobs/mainboard/\$(MAINBOARDDIR)/low_battery.bmp" endif endmenu config HAVE_EARLY_POWEROFF_SUPPORT bool help Enable platform-specific early power off support. This option should be selected if the platform requires special handling to power off the system before memory initialization. This is often necessary on Intel platforms, as directly powering off before memory initialization is typically not supported by the chipset. Selecting this option indicates that the platform implements the `platform_do_early_poweroff()` function, which performs the necessary hardware operations to initiate an early power off sequence. This might involve configuring hardware registers, sending commands to power management controllers, or other platform-specific operations.
