romulus: Remove avbus-workaround
This was a workaround for DD1 (pre-production) hardware. Jordan Keuseman <jkeusema@us.ibm.com> wrote: > That was an issue back in DD1 time frame where the VRM needed to > change their signal voltage thresholds for AVS bus to work around a > problem where the processor was putting out a runt pulse in the final > bit of the transaction. They fixed that in the silicon so we got rid > of the work around. This was removed from Witherspoon when dropping DD1 support from OpenBMC. We can remove it from Romulus and other platforms too. (From meta-ibm rev: baedc91099960c0e582a98e465e190ff9c3aa9cc) Change-Id: I8266c154505d3b4fb268cd7c44aa84f5a4be0301 Signed-off-by: Joel Stanley <joel@jms.id.au> Signed-off-by: Brad Bishop <bradleyb@fuzziesquirrel.com>
