[U-Boot-Users] SCSI support for MIB405 board

[U-Boot-Users] SCSI support for MIB405 board

[Wolfgang Denk]

Dear Denis,

can you tell me something about  the  SCSI  support  in  the  current
versions of U-Boot? It seems the MIB405 board (maintained by you) has
SCSI  support  enabled, but the whole code in common/cmd_scsi.c seemd
to be unused - for example,  there  is  no  caller  of  do_scsi()  or
do_scsiboot() anywhere in the whole source tree?

Best regards,

Wolfgang Denk

In general, they do what you want, unless you want consistency.

[U-Boot-Users] Re: SCSI support for MIB405 board

[Denis Peter]

Dear Wolfgang,

the MIP405 has no SCSI chip on board, and the SCSI Support isn't enabled 
for this board. SCSI support has been added to the PIP405 board, which is 
more or less a dead project. The state of this project is the reason, why 
the U-Boot has not been tested on the PIP405 some time ago.
The code for the SCSI has been added before the introduction of the macros 
"U_BOOT_CMD", and it seems that these macros are missing for do_scsi() and 
do_scsiboot().
I can add these macros, test it on the PIP405 and send you a patch, but it 
may took some time.

With best regards,

Denis

But there is a lot of SCSI-specific stuff in the config file:

MIP405.h: * SCSI support (experimental) only SYM53C8xx supported
MIP405.h:#undef CONFIG_SCSI_SYM53C8XX
MIP405.h:#ifdef CONFIG_SCSI_SYM53C8XX
MIP405.h:#define CFG_SCSI_MAX_LUN       8 /* number of supported LUNs */
MIP405.h:#define CFG_SCSI_MAX_SCSI_ID   7 /* maximum SCSI ID (0..6) */
MIP405.h:#define CFG_SCSI_MAX_DEVICE    CFG_SCSI_MAX_SCSI_ID * CFG_SCSI_MAX_LUN /* maximum Target devices */
MIP405.h:#define CFG_SCSI_SPIN_UP_TIME  2
MIP405.h:#endif /* CONFIG_SCSI_SYM53C8XX */

That would be excellent.  Thanks in advance.

Here the Changelog entry (if needed):

CHANGELOG:
* Patch by Denis Peter, 6 Dec 2004

As usual, this being a 1.3.x release, I haven't  even  compiled  this
kernel yet. So if it works, you should be doubly impressed.
