choice
prompt "Tianocore payload"
default TIANOCORE_UEFIPAYLOAD
help
Select which type of payload Tianocore will build (default is UefiPayload)
UefiPayload: MrChromebox's customized fork of Tianocore which works on most
x86_64 devices
Upstream: Use upstream Tianocore payload from https://github.com/tianocore/edk2
CorebootPayload: MrChromebox's customized fork of the deprecated CorebootPayloadPkg
Tianocore build target. It may work better on some older hardware (eg, x230)
which does not work properly with the UefiPayloadPkg options.
config TIANOCORE_UEFIPAYLOAD
bool "UEFIPayload"
help
Select this option to build using MrChromebox's custom Tianocore fork,
which incorporates fixes/improvements from System 76's and 9elements' trees.
config TIANOCORE_UPSTREAM
bool "Upstream"
help
Select this option if you want to use upstream EDK2 to build Tianocore.

help
Select this option to build using MrChromebox's older (now deprecated)
CorebootPayloadPkg-based Tianocore branch

coreboot supports an array of build options which can be found below. These options
will only have an effect if the relevant options exist in the target repository.

help
Select this option to enable Above 4G Decode. This will allow the
payload to use all of the memory, rather than an maximum of 4G.
Disabling memory above 4G is useful for bootloaders that are not
fully 64-bit aware such as Qubes R4.0.4 bootloader.
config TIANOCORE_BOOTSPLASH_FILE
string "Tianocore Bootsplash path and filename"
default "bootsplash.bmp"
help
Select this option if you have a bootsplash image that you would
like to be used. If this option is not selected, the default
coreboot logo (European Brown Hare) will used.
The path and filename of the file to use as graphical bootsplash
image. The file must be an uncompressed BMP, in BMP 3 format.
Linux can create these with the below command:
`convert splosh.bmp BMP3:splash.bmp`
This image will also be used as the BGRT boot image, which may
persist through your OS boot process.
See ACPI spec 6.3, 5.2.22 Boot Graphics Resource Table (BGRT), and
Microsoft's documentation on BGRT positioning:
Docs/Windows/Windows Drivers/Bring up guide/Boot screen components
Accordingly, the image used should be no taller/wider than 40% of
the display panel's native pixel height/width (or resolution set).
If an absolute path is not given, the path will assumed to be
relative to the coreboot root directory.
config TIANOCORE_BOOT_MANAGER_ESCAPE
bool "Use Escape key for Boot Manager"

help
Use Escape as the hot-key to access the Boot Manager. This replaces
the default key of F2.
config TIANOCORE_BOOT_TIMEOUT
int
default 2
help
The length of time in seconds for which the boot splash/menu prompt will be displayed.
For boards with an internal display, the default value of 2s is generally sufficient.
For boards with an external display, a value of 5s is generally sufficient.

bool "Enable Tianocore logging to CBMEM"
help
Select this option if you want to enable Tianocore logging to CBMEM.
You may want to increase the default cbmem buffer size when selecting
this option, especially if using a debug (vs release) build.
Selecting this option will increase the payload size in CBFS by 0x10000.
config TIANOCORE_FOLLOW_BGRT_SPEC
bool "Center logo 38.2% from the top of screen"

help
Follow the BGRT Specification implemented by Microsoft and
the Boot Logo will be vertically centered 38.2% from the
top of the display.
