[MTD] Nuke IVR leftovers
Support for the ITE8172 based boards was deleted a while ago so this is dead code. The Kconfig dependency on MIPS was wrong anyway, MIPS is a processor architecture and nothing else; guesses on systems architecture are likely to be wrong ...

This provides a mapping driver for the Integrated Technology

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
