Our hardware has one flash memory in 16bit mode. CPU is SH4 of Hitachi.
That is 32bit type CPU and can connect the device in 16bit mode.
In this case, interleave is 1 and bus width is 2.

Before using  cfi->device_type instead of CFI_DEVICETYPE_X8
MTD driver cannot calculate the address of the CFI command correctly.
