Define Documentation

#define MEM_MSG (  _status   )     _msg_report ((_status), 0, __VA_ARGS__)

MSG signaller. Configuration-dependent message signaller. For boot configuration, returns _status. For application configuration, calls _msg_report(). Parameters: _status  The variable holding the status code. ...  The message specific parameter values.

Function Documentation

unsigned int Mem_ValidateMemoryRange (  const MEM_Descriptor *  md, const MEM_mapAccessType  accessType, const mem_mapEntry **  mapEntry )

Validate memory descriptor against memory map table. This function verifies that a memory descriptor is valid for a given set of access types. Potential access types are specified in accessType as a bitfield. If at least one of the access types specified is legal for the memory descriptor, a handle to the appropriate memory map entry is passed back for future use. If, instead, the caller wants to know if *all* specified access types are valid, then this function must be called once for each type. Parameters: md  Pointer to memory descriptor to be validated. accessType  Bitfield of types of accesses to validate. mapEntry  Pointer to location to return map table entry handle. Return values: MEM_SUCCESS  md is OK for accessType. MEM_OUTOFRNG  md does not fit in any memory map. MEM_BADMAP  md does not contain a legal memory map type. MEM_BADACC  accessType is not legal for md.

void * Mem_WriteRegisterSet (  void *  data_p, void *  mask_p )

Write CPU registers. Writes a subset of the CPU registers. Parameters: data_p  Pointer to array of data values to write. mask_p  Pointer to array of mask values to apply to the data. Returns: Sum of data_p and the number of bytes written.
