- * Within SMC chip select address space, lines A[23:21] distinguish Compact
- * Flash modes (I/O, common memory, attribute memory, True IDE). IDE modes are:
- * 0x00c0000 - True IDE
- * 0x00e0000 - Alternate True IDE (Alt Status Register)
- *
- * On True IDE mode Task File and Data Register are mapped at the same address.
- * To distinguish access between these two different bus data width is used:
- * 8Bit for Task File, 16Bit for Data I/O.
- *
- * After initialization we do 8/16 bit flipping (changes in SMC MODE register)
- * only inside IDE callback routines which are serialized by IDE layer,
- * so no additional locking needed.
