[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.

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.
