From e4dff872fe97f6e48a26aebddec3ff57ddd43398 Mon Sep 17 00:00:00 2001 From: Dick Kennedy Date: Fri, 29 Sep 2017 17:34:42 -0700 Subject: [PATCH] scsi: lpfc: Fix secure firmware updates [ Upstream commit 184fc2b9a8bcbda9c14d0a1e7fbecfc028c7702e ] Firmware update fails with: status x17 add_status x56 on the final write If multiple DMA buffers are used for the download, some firmware revs have difficulty with signatures and crcs split across the dma buffer boundaries. Resolve by making all writes be a single 4k page in length. Signed-off-by: Dick Kennedy Signed-off-by: James Smart Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K.
