Reset Command Sticky #2

Management Processor CPLD: MPC8548 PLD Register

Note: The board powers down and powers back up when the Cavium processors power is back up (bits 0 or 1 are cleared).

Bits:	Function:	Description:
7	CAV1C	Cavium 1 Complex reset

6	CAV2C	Cavium 2 Complex reset

5	SWIC	Switch Complex reset

4	CAV1CF	Cavium 1 Complex 4MB Flash reset

3	CAV2CF	Cavium 2 Complex 4MB Flash reset

2	NANDF	NAND Flash reset

1	CAV2RPD	Reset and power down the Cavium 2 core

0	CAV1RPD	Reset and power down the Cavium 1 core

The read/write Reset Command Sticky #2 register forces one of several types of the PHY reset command, as shown below. A reset sequence is first initiated by writing a one to one or more bits, then the PLD performs that particular reset. The bit will persist until cleared.

Bits:	Function:	Description:
7	TSEC1R	TSEC1 Ethernet to front panel PHY Reset

6	TSEC2R	TSEC2 Ethernet to switch PHY Reset

5	FPIR	FPI Ethernet from switch to front panel PHY Reset

4	BCR	Ethernet dual PHY to backplane Base Channel Reset

3	MIP1	SPI to XAUI bridge #1 on Cavium 1

2	MIP2	SPI to XAUI bridge #2 on Cavium 1

1	MIP3	SPI to XAUI bridge #3 on Cavium 2

0	MIP4	SPI to XAUI bridge #4 on Cavium 2

Boot Device Redirection

The read/write Boot Device Redirection register (BDRR) allows the user to determine which of three boot devices the MPC8548 CPU is using as the boot device. Several bits also indi- cate which device was set as the initial boot device. The Boot Redirected bit is set to a 1 when the current boot device does not match the initial default boot device. This indicates to the user that the image in the default device was bad, the MPC8548 watch dog timer expired, and the next device was tried. The boot device redirection order is determined by IPMC. Reference the “Boot Device Diagram”.
