Hi, Attached patches fix a few problems with ESP scsi card emulation. Misc fixes (esp_1_misc.diff)- Fix internal fifo size (16 bytes), according to http://www.ibiblio.org/pub/historic-linux/early-ports/Sparc/NCR/NCR53C9X.txt
- Fix values of STAT_MI and STAT_MO - Give a scsi ID to adapter, and prevent this ID to be used by devices - Prevent fifo overrun in esp_mem_writeb - Add a ESP_ERROR macro, and use it where appropriate Fix configuration 2 register (esp_2_cfg2.diff):According to http://www.ibiblio.org/pub/historic-linux/early-ports/Sparc/NCR/NCR53C9X.txt , "Any bit pattern written to this register
may be read back and should be identical" Fix command len detection (esp_3_cmdlen.diff)When command is not DMA, TCMID and TCLO registers are not filled. Use command buffer len instead
Fix 'enable selection' command (esp_4_ensel.diff) Indicate success after 'enable selection' command Signed-off-by: Hervé Poussineau <address@hidden> These patches have been tested on Sparc SS-5 and on Mips Magnum emulations. Hervé
