On some architectures there is currently no way for the boot loader
to pass arguments to the kernel. For these architectures, you should
supply some command-line options at build time by entering them
here.

Set this to have arguments from the default kernel command string
override those passed by the boot loader.

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.

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.

config HIGHMEM_START_BOOL

This option allows you to set the base address of the kernel virtual
area used to map high memory pages. This can be useful in
optimizing the layout of kernel virtual memory.
Say N here unless you know what you are doing.

depends on ADVANCED_OPTIONS
help
This option allows you to set the maximum amount of memory which
will be used as "low memory", that is, memory which the kernel can
access directly, without having to set up a kernel virtual mapping.
This can be useful in optimizing the layout of kernel virtual
memory.
Say N here unless you know what you are doing.

config KERNEL_START_BOOL
bool "Set custom kernel base address"
depends on ADVANCED_OPTIONS
help
This option allows you to set the kernel virtual address at which
the kernel will map low memory (the kernel image will be linked at
this address). This can be useful in optimizing the virtual memory
layout of the system.
Say N here unless you know what you are doing.

This option allows you to set the amount of virtual address space
allocated to user tasks. This can be useful in optimizing the
virtual memory layout of the system.
