	  On some architectures there is currently no way for the boot loader

	  supply some command-line options at build time by entering them
	  here.

	help
	  This kernel feature is useful for number crunching applications
	  that may need to compute untrusted bytecode during their
	  execution. By using pipes or other transports made available to
	  the process as file descriptors supporting the read/write
	  syscalls, it's possible to isolate those applications in
	  their own address space using seccomp. Once seccomp is
	  enabled via /proc/<pid>/seccomp, it cannot be disabled
	  and the task is only allowed to execute a few safe syscalls
	  defined by each seccomp mode.

	  If unsure, say Y. Only embedded should say N here.

	  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.

	  This is needed to be able to allocate uncachable memory regions.
	  The feature requires the design to define the RAM memory controller
	  window to be twice as large as the actual physical memory.

config HIGHMEM
	bool "High memory support"
	depends on MMU
	help
	  The address space of Microblaze processors is only 4 Gigabytes large
	  and it has to accommodate user address space, kernel address
	  space as well as some memory mapped IO. That means that, if you
	  have a large amount of physical memory and/or IO, not all of the
	  memory can be "permanently mapped" by the kernel. The physical
	  memory that is not permanently mapped is called "high memory".

	  If unsure, say n.

config LOWMEM_SIZE_BOOL
	bool "Set maximum low memory"
	depends on ADVANCED_OPTIONS && MMU
	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.

	help
	  Set this option to have the kernel override the CPU Reset vector.
	  If zero, no change will be made to the MicroBlaze reset vector at
	  address 0x0.
	  If non-zero, a jump instruction to this address, will be written
	  to the reset vector at address 0x0.
	  If you are unsure, set it to default value 0x0.

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.

	depends on ADVANCED_OPTIONS && MMU
	help
	  This option allows you to set the amount of virtual address space
	  allocated to user tasks.  This can be useful in optimizing the

choice
	prompt "Page size"
	default MICROBLAZE_4K_PAGES
	depends on ADVANCED_OPTIONS && !MMU
	help
	  Select the kernel logical page size. Increasing the page size
	  will reduce software overhead at each page boundary, allow
	  hardware prefetch mechanisms to be more effective, and allow
	  larger dma transfers increasing IO efficiency and reducing
	  overhead. However the utilization of memory will increase.
	  For example, each cached file will using a multiple of the
	  page size to hold its contents and the difference between the
	  end of file and the end of page is wasted.

	  If unsure, choose 4K_PAGES.
