This will subject the whole payload to the terms of this license (including its provision to release all sources, please see the LICENSE_GPL file for details). config EXPERIMENTAL bool "Experimental Options" default n help Prompt for experimental functionality. Attention: This is not likely to work without problems config OBSOLETE bool "Obsolete Options" default n help Prompt for obsolete options. These options are for old, unsupported features and are likely to go away in the future. config DEVELOPER bool "Developer Options" default n help Prompt for developer options. These options are only interesting for libpayload developers. config REMOTEGDB bool "Remote GDB stub" default n depends on GPL help Enable Remote GDB debugging support. config CHROMEOS bool "ChromeOS specific features" default n help Enable ChromeOS specific features. endmenu menu "Architecture Options" choice prompt "Target Architecture" default ARCH_X86 config ARCH_ARM bool "ARM" help Support the ARM architecture config ARCH_X86 bool "x86" help Support the x86 architecture config ARCH_ARM64 bool "ARM64" help Support the ARM64 architecture config ARCH_MIPS bool "MIPS" help Support the MIPS architecture endchoice config MEMMAP_RAM_ONLY bool "Only consider RAM entries in memory map for further processing" default n config MULTIBOOT bool "Multiboot header support" depends on ARCH_X86 default y endmenu menu "Standard Libraries" config LIBC bool "Enable C library support" default y config CURSES bool "Build a curses library" default y choice prompt "Curses implementation" default PDCURSES depends on CURSES config TINYCURSES bool "Tinycurses" help Tinycurses was the first curses implementation for libpayload. It features low memory consumption, static allocation of larger data structures (so few or no memory allocation calls) and a reduced feature set. config PDCURSES bool "PDCurses" help libpayload's PDCurses port provides a full features curses implementation, including libpanel, libmenu and libform (which are taken from ncurses). It requires more system resources, in particularily heap memory. endchoice config LAR bool "LAR support" default n depends on OBSOLETE help LAR is the archive format of (obsolete) coreboot v3 config CBFS bool "CBFS support" default y help CBFS is the archive format of coreboot config LZMA bool "LZMA decoder" default y help LZMA decoder implementation, usable eg. by CBFS, but also externally. endmenu menu "Console Options" config SKIP_CONSOLE_INIT bool "Skip initializing the consoles at startup" default n help Normally, libpayload will initialize console input/output on startup before the payload itself gets control. This option disables that behavior and leaves console initialization up to the payload. config CBMEM_CONSOLE bool "Send output to the in memory CBMEM console" default y config SERIAL_CONSOLE bool "See output on the serial port console" default y config 8250_SERIAL_CONSOLE bool "8250, 16450, 16550, 16550A compatible serial port driver" depends on SERIAL_CONSOLE default y if ARCH_X86 default n if !ARCH_X86 config S5P_SERIAL_CONSOLE bool "Exynos SOC, S5P compatible serial port driver" depends on SERIAL_CONSOLE default n config 8250_MMIO32_SERIAL_CONSOLE bool "Memory-mapped 8250-compatible serial port driver with 32-bit regs" depends on SERIAL_CONSOLE default n config IPQ806X_SERIAL_CONSOLE bool "IPQ806x SOC compatible serial port driver" depends on SERIAL_CONSOLE default n config BG4CD_SERIAL_CONSOLE bool "Serial port driver for Marvell's BG4CD" depends on SERIAL_CONSOLE default n config PL011_SERIAL_CONSOLE bool "PL011 compatible serial port driver" depends on 8250_SERIAL_CONSOLE default n config SERIAL_IOBASE ## This default is currently not used on non-x86 systems. hex "Default I/O base for the serial port (default 0x3f8)" depends on SERIAL_CONSOLE && ARCH_X86 default 0x3f8 config SERIAL_SET_SPEED bool "Override the serial console baud rate" default n depends on SERIAL_CONSOLE config SERIAL_BAUD_RATE int "Serial console baud rate (default 115200)" depends on SERIAL_SET_SPEED default 115200 config SERIAL_ACS_FALLBACK bool "Use plain ASCII characters for ACS" default n depends on SERIAL_CONSOLE help The alternate character set (ACS) is used for drawing lines and displaying a couple of other special graphics characters. The ACS characters generally look good on screen, but can be difficult to cut and paste from a terminal window to a text editor. Say 'y' here if you want to always use plain ASCII characters to approximate the appearance of ACS characters on the serial port console. config VIDEO_CONSOLE bool "See output on a video console" default y config VGA_VIDEO_CONSOLE bool "VGA video console driver" depends on ARCH_X86 && VIDEO_CONSOLE default y config GEODELX_VIDEO_CONSOLE bool "Geode LX video console driver" depends on ARCH_X86 && VIDEO_CONSOLE default n config COREBOOT_VIDEO_CONSOLE bool "coreboot video console driver" depends on VIDEO_CONSOLE && !GEODELX_VIDEO_CONSOLE default n help Say Y here if coreboot switched to a graphics mode and your payload wants to use it. config PC_KEYBOARD bool "Allow input from a PC keyboard" default y if ARCH_X86 # uses IO default n config PC_KEYBOARD_LAYOUT_US bool "English (US) keyboard layout" depends on PC_KEYBOARD default y config PC_KEYBOARD_LAYOUT_DE bool "German keyboard layout" depends on PC_KEYBOARD default n endmenu menu "Drivers" config PCI bool "Support for PCI devices" depends on ARCH_X86 # for now default y config NVRAM bool "Support for reading/writing NVRAM bytes" depends on ARCH_X86 # for now default y config RTC_PORT_EXTENDED_VIA bool "Extended RTC ports are 0x74/0x75" default n help For recent chipsets with 256 NVRAM bytes, you have to access the upper 128 bytes (128-255) using two different I/O ports, usually 0x72/0x73. On some chipsets this can be a different set of ports, though. The VIA VT8237R for example only recognizes the ports 0x74/0x75 for accessing the high 128 NVRAM bytes (as seems to be the case for multiple VIA chipsets). If you want to read or write CMOS bytes on computers with one of these chipsets, say 'y' here. config SPEAKER bool "Support for PC speaker" depends on ARCH_X86 default y config STORAGE bool "Support for storage devices" default y help Select this option if you want support for storage devices (like hard drives, memory sticks or optical drives). config STORAGE_64BIT_LBA bool "Use 64-bit integers to address sectors" depends on STORAGE default n help If this is selected, sectors will be addressed by an 64-bit integer.
