| Subject: scsi: lpfc: Fix secure firmware updates |
| |
| From: Dick Kennedy <dick.kennedy@broadcom.com> |
| |
| |
| [ 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. |
