The introduction of the new CPU architecture and board support
leads to the update of existing header files. Are added:
- functions and macros to manipulate bits of registers field values.
- external declaration of cache handling functions to prevent
compilation warnings.
- new processor definitions.
- macros (in replacement of existing definitions) to set 85xx TLB
registers.
