From e8c84b19733172bc68ff9fde90981464e9aab443 Mon Sep 17 00:00:00 2001 From: Mark Cave-Ayland Date: Fri, 12 Jan 2024 12:53:34 +0000 Subject: [PATCH] esp.c: convert do_dma_pdma_cb() do_cmd path to check for SCSI phase instead Currently do_cmd is used to determine whether MESSAGE OUT and COMMAND phase data is being accumulated in cmdfifo. Update esp_do_dma() to check directly for these two SCSI phases instead.
