Mike Frysinger dcb3e137ce [MTD] physmap: make physmap compat explicit 
The current method for always showing physmap compat address, size, and
width is a bit confusing.  If length is set to 0, then the address and
width are still shown but silently unused.  The physmap code itself
already has logic which sets compat based on length, so just pull that out
and into the Kconfig to make everything clear.

# drivers/mtd/maps/Kconfig
menu "Mapping drivers for chip access"
depends on MTD!=n
config MTD_COMPLEX_MAPPINGS
bool "Support non-linear mappings of flash chips"
help
This causes the chip drivers to allow for complicated
paged mappings of flash chips.
config MTD_PHYSMAP
tristate "CFI Flash device in physical memory map"
depends on MTD_CFI || MTD_JEDECPROBE || MTD_ROM
help
This provides a 'mapping' driver which allows the NOR Flash and
ROM driver code to communicate with chips which are mapped
physically into the CPU's memory. You will need to configure
the physical address and size of the flash chips on your
particular board as well as the bus width, either statically
with config options or at run-time.
To compile this driver as a module, choose M here: the
module will be called physmap.
config MTD_PHYSMAP_COMPAT
bool "Physmap compat support"
depends on MTD_PHYSMAP
default n
help
Setup a simple mapping via the Kconfig options. Normally the
physmap configuration options are done via your board's
resource file.
If unsure, say N here.
config MTD_PHYSMAP_START
hex "Physical start address of flash mapping"
depends on MTD_PHYSMAP_COMPAT
default "0x8000000"
help
This is the physical memory location at which the flash chips
are mapped on your particular target board. Refer to the
memory map which should hopefully be in the documentation for
your board.
Ignore this option if you use run-time physmap configuration
(i.e., run-time calling physmap_configure()).
config MTD_PHYSMAP_LEN
hex "Physical length of flash mapping"
depends on MTD_PHYSMAP_COMPAT
default "0"
help
This is the total length of the mapping of the flash chips on
your particular board. If there is space, or aliases, in the
physical memory map between the chips, this could be larger
than the total amount of flash present. Refer to the memory
map which should hopefully be in the documentation for your
board.
Ignore this option if you use run-time physmap configuration
(i.e., run-time calling physmap_configure()).
config MTD_PHYSMAP_BANKWIDTH
int "Bank width in octets"
depends on MTD_PHYSMAP_COMPAT
default "2"
help
This is the total width of the data bus of the flash devices
in octets. For example, if you have a data bus width of 32
bits, you would set the bus width octet value to 4. This is
used internally by the CFI drivers.
Ignore this option if you use run-time physmap configuration
(i.e., run-time calling physmap_configure()).
config MTD_PHYSMAP_OF
tristate "Flash device in physical memory map based on OF description"
depends on PPC_OF && (MTD_CFI || MTD_JEDECPROBE || MTD_ROM)
help
This provides a 'mapping' driver which allows the NOR Flash and
ROM driver code to communicate with chips which are mapped
physically into the CPU's memory. The mapping description here is
taken from OF device tree.

on PMC MSP devices. This memory is mapped as a MTD block device.
config MTD_SUN_UFLASH
tristate "Sun Microsystems userflash support"
depends on SPARC && MTD_CFI && PCI
help
This provides a 'mapping' driver which supports the way in
which user-programmable flash chips are connected on various
Sun Microsystems boardsets. This driver will require CFI support
in the kernel, so if you did not enable CFI previously, do that now.
config MTD_SC520CDP

select MTD_PARTITIONS
select MTD_JEDECPROBE
select MTD_CFI_AMDSTD
help
This provides a driver for the on-board flash of the Technologic
System's TS-5500 board. The 2MB flash is split into 3 partitions
which are accessed as separate MTD devices.
mtd0 and mtd2 are the two BIOS drives, which use the resident
flash disk (RFD) flash translation layer.
mtd1 allows you to reprogram your BIOS. BE VERY CAREFUL.
Note that jumper 3 ("Write Enable Drive A") must be set
otherwise detection won't succeed.
config MTD_SBC_GXX
tristate "CFI Flash device mapped on Arcom SBC-GXx boards"
depends on X86 && MTD_CFI_INTELEXT && MTD_PARTITIONS && MTD_COMPLEX_MAPPINGS
