Detailed Description

Interface to RAD750 SUROM services.

-----------------------------------------------------------------------------

Description:

This header file defines a common interface to underlying facilities (i.e., services, data) that may be provided by a Rad750 SUROM. The implementation is provided as part of the BSP (in target/config/bsp_name), since SUROM is board dependent.

Restrictions:

• These services are not re-entrant.

Function Documentation

STATUS sysSuromSetupClkChange (  UINT32  clkCtrlReg, UINT32  pllReg, UINT32  mpSigMask )

Setup EMC clock change parameters. This routine writes the the EMC SUROM command block to request changes to the CPU clock settings. No parameter validation is performed by this routine and sysSuromSignalServiceRequest() must be called to signal EMC SUROM to service the Change Clock request. Parameters: clkCtrlReg  - Value to be written to the PPCI CAT core Clock Control reg. pllReg  - Value to be written to the PPCI CAT core PLL Setup/Config regs (e.g., 0x17 for a PLL of 3.5). mpSigMask  - If 0, reset 750 after clock change. Otherwise, value written to Multiprocessor Signaling reg after clock change. Returns: OK or ERROR.

STATUS sysSuromSignalServiceRequest (  void   )

Do EMC clock change operation. This routine signals EMC SUROM to service the request in it's command block. Returns: OK or ERROR.
