From b17424b0b29f94561e73ab9be34037746b378089 Mon Sep 17 00:00:00 2001 From: Steve Hodgson Date: Wed, 28 Apr 2010 09:25:22 +0000 Subject: [PATCH] sfc: Ignore parity errors in the other port's SRAM Siena has a separate SRAM bank for each port. On single-port boards these can be merged together, so each port has an interrupt flag for parity errors in the other port's SRAM. Currently we do not enable such merging and should mask this interrupt source. Signed-off-by: Ben Hutchings Signed-off-by: David S.
