The existing TCE machine calls (tce_build and tce_free) only support
virtual mode as they call __raw_writeq for TCE invalidation what
fails in real mode.
This introduces tce_build_rm and tce_free_rm real mode versions
which do mostly the same but use "Store Doubleword Caching Inhibited
Indexed" in
Add this file to help detect cpu type in runtime.
These macros and inline routines will be more favorable for driver
to apply errata and workaround to specified cpu type.

Command complete interrupt not always generate within 10 * HZ. Sometimes
500 * HZ or more. So enlarge this detecting value to ensure the host had

On T4240 board controllers has an unusable ADMA engine, so use SDMA instead.
Also 3.0v is support on T4240 board even if the capacity detailed only 1.8v
