For these architectures, you should supply some command-line options at build time by entering them here. config CMDLINE_FORCE bool "Force default kernel command string" depends on CMDLINE_BOOL default n help Set this to have arguments from the default kernel command string override those passed by the boot loader. config OF def_bool y config PROC_DEVICETREE bool "Support for device tree in /proc" depends on PROC_FS help This option adds a device-tree directory under /proc which contains an image of the device tree that the kernel copies from Open Firmware or other boot firmware. If unsure, say Y here. endmenu menu "Advanced setup" config ADVANCED_OPTIONS bool "Prompt for advanced kernel configuration options" depends on MMU help This option will enable prompting for a variety of advanced kernel configuration options. These options can cause the kernel to not work if they are set incorrectly, but can be used to optimize certain aspects of kernel memory management. Unless you know what you are doing, say N here. comment "Default settings for advanced configuration options are used" depends on !ADVANCED_OPTIONS config HIGHMEM_START_BOOL bool "Set high memory pool address" depends on ADVANCED_OPTIONS && HIGHMEM help This option allows you to set the base address of the kernel virtual area used to map high memory pages.
