[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. Signed-off-by: Greg Ungerer <gerg@uclinux.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

+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.
