Fusion-MPT with 53C1030 and no flash?

[Matthew Dharm]

[-- Attachment #1: Type: text/plain, Size: 680 bytes --]

Has anyone ever used an LSI 53C1030 chip WITHOUT attached flash?

As I read the technical docs, it's possible... but it requires a driver
which can download the firmware to the ARM processor.  It looks like the
current 2.6.x driver can't do that.

In fact, I can't seem to locate a suitable firmware image anywhere...

Does anyone have any experience in this area they could share?

Matt,

I've not done it with the 53C1030, but I have done it (outside of Linux)
with the 929 & 929X FC chips.  For that, the same firmware file was used
as for writing to flash.  I think the details of how were given under
NDA, so I can't get specific (as I recall, it involved knowing some of
the address map, which is probably different on the 53C1030 anyways).
So you probably need to talk to LSI about it.

Yes this works. In embedded environment w/o flash, the firmware is
packaged with the system bios, and downloaded to the part via the 1030
option rom.

Look at mpt_downloadboot in mptbase.c

That's assuming we have an x86-like BIOS..... as least, given the files
I've seen on the LSI web page which are all x86-oriented.  I'm working on a
PPC64 embedded target where by loader/boot code won't (for various reasons
which are not all technical) touch this chip.

Did that already.  The references to mpt_downloadboot are:
	1) in the disable routine
	2) the hard reset routine

If this is called by some code path I don't immediately see (and I'll admit
that's a very real possibility), mpt_downloadboot wants the firmware in the
ioc->cached_fw pointer.

I don't see a way to get it there except by downloading it from a running
adaptor (before doing a reset, I presume).

I've also been to this page before.  The driver download doesn't seem to
contain the firmware, either.

The BIOS/Firmware download contains a couple of binaries, but no
information on how to use them except with the DOS tool to program them
into an option ROM.

Without information on the firmware file map, at the least, I don't see how
that binary is useful.  Heck, that firmware image might not even be useable
if loaded directly into the part's internal RAM.
