This enables the NAND flash driver on the PPChameleon EVB Board.
config MTD_NAND_DISKONCHIP
tristate "DiskOnChip 2000 and Millennium (NAND reimplementation) (EXPERIMENTAL)"
tristate "DiskOnChip 2000, Millennium and Millennium Plus (NAND reimplementation) (EXPERIMENTAL)"
depends on MTD_NAND && EXPERIMENTAL
help
This is a reimplementation of M-Systems DiskOnChip 2000 and
Millennium as a standard NAND device driver, as opposed to the
earlier self-contained MTD device drivers.
This is a reimplementation of M-Systems DiskOnChip 2000,
Millennium and Millennium Plus as a standard NAND device driver,
as opposed to the earlier self-contained MTD device drivers.
This should enable, among other things, proper JFFS2 operation on
these devices.
config MTD_NAND_DISKONCHIP_PROBE_ADVANCED
bool "Advanced detection options for DiskOnChip"
depends on MTD_NAND_DISKONCHIP
help
This option allows you to specify nonstandard address at which to
probe for a DiskOnChip, or to change the detection options. You
are unlikely to need any of this unless you are using LinuxBIOS.
Say 'N'.
config MTD_NAND_DISKONCHIP_PROBE_ADDRESS
hex "Physical address of DiskOnChip" if MTD_NAND_DISKONCHIP_PROBE_ADVANCED
depends on MTD_NAND_DISKONCHIP
default "0"
---help---
By default, the probe for DiskOnChip devices will look for a
DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.
This option allows you to specify a single address at which to probe
for the device, which is useful if you have other devices in that
range which get upset when they are probed.
(Note that on PowerPC, the normal probe will only check at
0xE4000000.)
Normally, you should leave this set to zero, to allow the probe at
the normal addresses.
config MTD_NAND_DISKONCHIP_PROBE_HIGH
bool "Probe high addresses"
depends on MTD_NAND_DISKONCHIP_PROBE_ADVANCED
help
By default, the probe for DiskOnChip devices will look for a
DiskOnChip at every multiple of 0x2000 between 0xC8000 and 0xEE000.
This option changes to make it probe between 0xFFFC8000 and
0xFFFEE000. Unless you are using LinuxBIOS, this is unlikely to be
useful to you. Say 'N'.
