# --------------------------------------------------------------------
|

# Extract from openembedded-core 'uboot-extlinux-config.bbclass' class
|
||||
# --------------------------------------------------------------------
|
||||
# External variables:
|
||||
#
|
||||
# UBOOT_EXTLINUX_CONSOLE - Set to "console=ttyX" to change kernel boot
|
||||
# default console.
|
||||
# UBOOT_EXTLINUX_LABELS - A list of targets for the automatic config.
|
||||
# UBOOT_EXTLINUX_KERNEL_ARGS - Add additional kernel arguments.
|
||||
# UBOOT_EXTLINUX_KERNEL_IMAGE - Kernel image name.
|
||||
# UBOOT_EXTLINUX_FDTDIR - Device tree directory.
|
||||
# UBOOT_EXTLINUX_FDT - Device tree file.
|
||||
# UBOOT_EXTLINUX_INITRD - Indicates a list of filesystem images to
|
||||
# concatenate and use as an initrd (optional).
|
||||
# UBOOT_EXTLINUX_MENU_DESCRIPTION - Name to use as description.
|
||||
# UBOOT_EXTLINUX_ROOT - Root kernel cmdline.
|
||||
# UBOOT_EXTLINUX_TIMEOUT - Timeout before DEFAULT selection is made.
|
||||
# Measured in 1/10 of a second.
|
||||
# UBOOT_EXTLINUX_DEFAULT_LABEL - Target to be selected by default after
|
||||
# the timeout period
|
||||
#
|
||||
# If there's only one label system will boot automatically and menu won't be
|
||||
# created. If you want to use more than one labels, e.g linux and alternate,
|
||||
# use overrides to set menu description, console and others variables.
|
||||
#
|
||||
# --------------------------------------------------------------------
|
||||
# STM32MP specific implementation
|
||||
# --------------------------------------------------------------------
|
||||
# Append new mechanism to allow multi 'extlinux.conf' file generation.
|
||||
# - multiple targets case:
|
||||
# each 'extlinux.conf' file generated is created under specific path:
|
||||
# '${B}/<UBOOT_EXTLINUX_BOOTPREFIXES>extlinux/extlinux.conf'
|
||||
# - simple target case:
|
||||
# the 'extlinux.conf' file generated is created under default path:
|
||||
# '${B}/extlinux/extlinux.conf'
|
||||
#
|
||||
# New external variables added:
|
||||
# UBOOT_EXTLINUX_TARGETS - A list of targets for multi config file
|
||||
# generation
|
||||
# UBOOT_EXTLINUX_BOOTPREFIXES - Bootprefix used in uboot script to select
|
||||
# extlinux.conf file to use
|
||||
#
|
||||
# --------------------------------------------------------------------
|
||||
# Output example:
|
||||
# --------------------------------------------------------------------
|
||||
# Following 'extlinux.conf' files are generated under ${UBOOT_EXTLINUX_INSTALL_DIR}:
|

# ${UBOOT_EXTLINUX_BOOTPREFIXES_${UBOOT_EXTLINUX_TARGETS}[0]}extlinux/extlinux.conf
