Linus Walleij 8f2c00629e ARM: realview: imply device tree boot 
This reduces the Kconfig for the RealView by assuming we are
always booting from the device tree, and removing all the uses
of CONFIG_REALVIEW_DT and replacing with CONFIG_ARCH_REALVIEW.

Further:

- Drop REALVIEW_HIGH_PHYS_OFFSET: we don't use this with device
  tree.

- Drop the REALVIEW_EB_ARM11MP_REVB option: we now handle this
  by simply using another device tree.

- Drop the PB1176 secure flash option: this is defined in the
  PB1176 device tree but marked as "disabled", so users who
  want to use it can simply enable it in the device tree and
  go hacking around.

menu "Mapping drivers for chip access"
depends on MTD!=n
depends on HAS_IOMEM
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 "Flash device in physical memory map"
depends on MTD_CFI || MTD_JEDECPROBE || MTD_ROM || MTD_LPDDR
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.
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.
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.
config MTD_PHYSMAP_OF
tristate "Memory device in physical memory map based on OF description"
depends on OF && (MTD_CFI || MTD_JEDECPROBE || MTD_ROM || MTD_RAM)
help
This provides a 'mapping' driver which allows the NOR Flash, ROM
and RAM 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.
config MTD_PHYSMAP_OF_VERSATILE
bool "Support ARM Versatile physmap OF"
depends on MTD_PHYSMAP_OF
depends on MFD_SYSCON
default y if (ARCH_INTEGRATOR || ARCH_VERSATILE || ARCH_REALVIEW)
help
This provides some extra DT physmap parsing for the ARM Versatile
platforms, basically to add a VPP (write protection) callback so
the flash can be taken out of write protection.
config MTD_PMC_MSP_EVM
tristate "CFI Flash device mapped on PMC-Sierra MSP"
depends on PMC_MSP && MTD_CFI
help
This provides a 'mapping' driver which supports the way
in which user-programmable flash chips are connected on the
PMC-Sierra MSP eval/demo boards.

depends on MSP_FLASH_MAP_LIMIT_32M
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
tristate "CFI Flash device mapped on AMD SC520 CDP"
depends on (MELAN || COMPILE_TEST) && MTD_CFI
help
The SC520 CDP board has two banks of CFI-compliant chips and one
Dual-in-line JEDEC chip. This 'mapping' driver supports that
arrangement, implementing three MTD devices.
config MTD_NETSC520
tristate "CFI Flash device mapped on AMD NetSc520"
depends on (MELAN || COMPILE_TEST) && MTD_CFI
help
This enables access routines for the flash chips on the AMD NetSc520
demonstration board. If you have one of these boards and would like
to use the flash chips on it, say 'Y'.
config MTD_TS5500
tristate "JEDEC Flash device mapped on Technologic Systems TS-5500"
depends on TS5500 || COMPILE_TEST
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_COMPLEX_MAPPINGS
help
This provides a driver for the on-board flash of Arcom Control
Systems' SBC-GXn family of boards, formerly known as SBC-MediaGX.
By default the flash is split into 3 partitions which are accessed
as separate MTD devices. This board utilizes Intel StrataFlash.
