|
|
* NOTE: This file has been automatically generated based on the
|
|
* XML files extracted from the TI RDT v1.0.0.4p Tool.
|
|
* Download from here: http://www.ti.com/product/omap4460
|
|
* This means that the file might not be optimal in terms of naming
|
|
* conventions for constants and registers (duplicated
|
|
* namespaces in register and device name etc.).
|
|
* Also, because of the underlying structure from the original XML
|
|
* it's possible that some constants appear multiple times (if they
|
|
* have slightly different descriptions for example).
|
|
*
|
|
* You want to clean that up before using the files for the first time!
