- tristate "Flash chip mapping on ITE QED-4N-S01B, Globespan IVR or custom board"
- depends on MIPS && MTD_CFI && MTD_JEDECPROBE && MTD_PARTITIONS
- help
- This provides a mapping driver for the Integrated Technology
- Express, Inc (ITE) QED-4N-S01B eval board and the Globespan IVR
- Reference Board. It provides the necessary addressing, length,
- buswidth, vpp code and addition setup of the flash device for
- these boards. In addition, this mapping driver can be used for
- other boards via setting of the CONFIG_MTD_CSTM_MIPS_IXX_START/
- LEN/BUSWIDTH parameters. This mapping will provide one mtd device
- using one partition. The start address can be offset from the
- beginning of flash and the len can be less than the total flash
- device size to allow a window into the flash. Both CFI and JEDEC
- probes are called.

-config MTD_CSTM_MIPS_IXX_START

- depends on MTD_CSTM_MIPS_IXX
- default "0x8000000"
- help
- This is the physical memory location that the MTD driver will
- use for the flash chips on your particular target board.
- Refer to the memory map which should hopefully be in the
- documentation for your board.
-
-config MTD_CSTM_MIPS_IXX_LEN
- hex "Physical length of flash mapping"
- depends on MTD_CSTM_MIPS_IXX
- default "0x4000000"
- help
- This is the total length that the MTD driver will use for the
- flash chips on your particular board. Refer to the memory
- map which should hopefully be in the documentation for your
- board.
-
-config MTD_CSTM_MIPS_IXX_BUSWIDTH
- int "Bus width in octets"
- depends on MTD_CSTM_MIPS_IXX
- default "2"
- help
- This is the total bus width of the mapping of the flash chips
- on your particular board.

- * Mapping of a custom board with both AMD CFI and JEDEC flash in partitions.
- * Config with both CFI and JEDEC device support.
- *
- * Basically physmap.c with the addition of partitions and
- * an array of mapping info to accomodate more than one flash type per board.
