From 3109e5ae0311e937d49a5325134e50b742ac5f4a Mon Sep 17 00:00:00 2001 From: Michael Schmitz Date: Thu, 12 Apr 2018 13:53:26 +1200 Subject: scsi: zorro_esp: New driver for Amiga Zorro NCR53C9x boards New combined SCSI driver for all ESP based Zorro SCSI boards for m68k Amiga. Code largely based on board specific parts of the old drivers (blz1230.c, blz2060.c, cyberstorm.c, cyberstormII.c, fastlane.c which were removed after the 2.6 kernel series for lack of maintenance) with contributions by Tuomas Vainikka (TCQ bug tests and workaround) and Finn Thain (TCQ bugfix by use of PIO in extended message in transfer). New Kconfig option and Makefile entries for new Amiga Zorro ESP SCSI driver included in this patch. Use DMA transfers wherever possible, with board-specific DMA set-up functions copied from the old driver code. Three byte reselection messages do appear to cause DMA timeouts. So wire up a PIO transfer routine for these instead. esp_reselect_with_tag explicitly sets esp->cmd_block_dma as target address for the message bytes but PIO requires a virtual address. Substiute kernel virtual address esp->cmd_block in PIO transfer call if DMA address is esp->cmd_block_dma and phase is message in. PIO code taken from mac_esp.c where the reselection timeout issue was debugged and fixed first, with minor macro and function rename.
