Advisory 3 SRIO Port0 Reset Issue

Revision(s) Affected: 1.3, 1.2, 1.1, 1.0

Details: The SERDES macro for SRIO should allow reset of individual 1× ports without

affecting the state of the other operational ports. There are dedicated MMR bits to reset

1× ports, which are the BLKn_EN (n=5..8) at offsets 0x60, 0x68, 0x70 and 0x78 for

C6457. However, the BLK5_EN, which controls reset for port0, also resets all other

ports. Therefore, it is impossible to reset port0 without affecting all other ports.

Workaround 1: There is no workaround for this advisory.
