[PATCH] m68knommu: configuration options for ROM region 



Use Kconfig options to setup the optional ROM region used on some
platforms. We used to define this in the linker script on a per
board basis. The configure options are more flexible and clean up
the linker script a lot.

comment "ROM configuration"



config ROM

	bool "Specify ROM linker regions"

	default n

	help

	  Define a ROM region for the linker script. This creates a kernel

	  that can be stored in flash, with possibly the text, and data

	  regions being copied out to RAM at startup.



config ROMBASE

	hex "Address of the base of ROM device"

	default "0"

	depends on ROM

	help

	  Define the address that the ROM region starts at. Some platforms

	  use this to set their chip select region accordingly for the boot

	  device.



config ROMVEC

	hex "Address of the base of the ROM vectors"

	default "0"

	depends on ROM

	help

	  This is almost always the same as the base of the ROM. Since on all

	  68000 type varients the vectors are at the base of the boot device

	  on system startup.



config ROMVECSIZE

	hex "Size of ROM vector region (in bytes)"

	default "0x400"

	depends on ROM

	help

	  Define the size of the vector region in ROM. For most 68000

	  varients this would be 0x400 bytes in size. Set to 0 if you do

	  not want a vector region at the start of the ROM.



config ROMSTART

	hex "Address of the base of system image in ROM"

	default "0x400"

	depends on ROM

	help

	  Define the start address of the system image in ROM. Commonly this

	  is strait after the ROM vectors.



config ROMSIZE

	hex "Size of the ROM device"

	default "0x100000"

	depends on ROM

	help

	  Size of the ROM device. On some platforms this is used to setup

	  the chip select that controls the boot ROM device.
