SoSoComm Dudes:
I was able to contact Davide Santo, AN2604 "Introduction to BestComm".
He admitted
the short commings of his document in the area of Firmware instruction
info and gave
me a name of a guy, Ed in the ASIC design area in Austin. Ed has agreed
to answer
questions, push for resources to provide a support tool and provided me
with a document
from their head programmer "SmartDMA Hand-Assembly Guides" (see attached
pdf).
With this secret decoded ring I was able to put together a disassembler,
see attached
disasm.c. Cut and paste your favorite Task into fw[] array at the
beginning,
"cc -o d disasm.c ; d" It's not perfect, but useful- Enjoy. Sorry I'm not
sure where or if you guys want to check this stuff into a git
repository, somewhere
and hope ozlabs is not fussy about attachments!
If we can formulate a list of questions Ed might be able to help, I'll
start:
o what does init=31 mean?
AN2604 say init=0 means always requestor and 31 is reserved but
referenced
alot in the F/W comments
o Need more info on how MORE works
o Tell us about LCD levels. Only 2? (let's call a LCD indent a level)
LCD seems to reset DRD to 1A. DRD2B1or2 follow a DRD2A (ext=1)?
o LCD[28:23]orLCD[20:15] or LCD[11:6] what is extraN?
drop 101nnn - extraN
add 1nnnnn - indexN
o how many DRD2B1[2] can be stacked up?
o when is/can a LDC Literal used? and how?

I can put it on line on a webserver. I guess Freescale gave you
permission to publish
this document ?

I'll read the document more deeply this week end with the task code
beside me,
try to see if some things are still unclear.

VERY, VERY BIG thanks to you :-))), finally we can do something more
sensible with it (like scatter-gather).

But it could be start point for a kernel compiler :).

I'll reread my drafts at next week too, so may be this list will be
extended.
