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

These patches have been tested on Sparc SS-5 and on Mips Magnum emulations.
