[ 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.
