From d607b9684b188d020a00e9cfaa502b782f29d538 Mon Sep 17 00:00:00 2001 From: Timur Tabi Date: Thu, 1 Nov 2012 08:20:23 +0000 Subject: powerpc/85xx: implement check for erratum A-004580 work-around The work-around for erratum A-004580 ("Internal tracking loop can falsely lock causing unrecoverable bit errors") is implemented via the PBI (pre-boot initialization code, typically attached to the RCW binary). This is because the work-around is easier to implement in PBI than in U-Boot itself. It is still useful, however, for the 'errata' command to tell us whether the work-around has been applied. For A-004580, we can do this by verifying that the values in the specific registers that the work-around says to update. This change requires access to the SerDes lane sub-structure in serdes_corenet_t, so we make it a named struct.
