From: David Abdurachmanov <david.abdurachmanov@sifive.com>

The order of interrupt numbers is incorrect.

The order for FU740 is: DirError, DataError, DataFail, DirFail

From SiFive FU740-C000 Manual:
19 - L2 Cache DirError
20 - L2 Cache DirFail
21 - L2 Cache DataError
22 - L2 Cache DataFail

There are a bunch of stuff that need to be cleaned up and synced with
U-Boot copy of DT for Unmatched.

This patch is required to boot.

There are others patches that do:
- Change compat string for CPUs to report U74MC instead of bullet0.
- Change memory to 16GB from 8GB.
- Change regulator values to match what's in the Rev3 board.
- Add PWM LEDs nodes.
- Add a gpio-poweroff node (this could change depending on what
OpenSBI wants to do).

And most likely the "a00" part should go away from compat strings and
filenames. "A00" was most likely a copy & paste from FU540 / Unleashed
board. Regulator block probably could also go away from DT as Linux
doesn't need to touch it, basically it just runs whatever is
configured in OTP.

I believe the current DT that landed was written for Rev1, but a few
revisions happened afterwards. You can only buy Rev3 boards.

I wonder if we should modify the existing DT file and rename it
"hifive-unmatched.dts" + new compat strings to remove "A00".

OK, I'm going to take it on fixes.  It seems this is an SOC issue while 
the others are board issues, and given that it's needed to boot I'd 
prefer to just take it.

> There are others patches that do:

You guys should just pick one there, the naming scheme is pretty 
inconsistent between the various projects/IPs.  I don't really care 
which one you pick, though, and even though I generally consider DT to 
be ABI-stable it sounds like this one landed a bit prematurely so I'm OK 
changing it.

> - Change memory to 16GB from 8GB.

Are you sure there are no boards out in the wild with 8GB of RAM?  If 
there are then we should have a DT for them, but if they're only in the 
lab then I'm fine simplifying things and just having one of them.

OK, though again I'd like to know that there aren't any pre-rev3 boards 
in the wild.

Seems reasonable to me.

Maybe it's best to hold off on that until there's agreement?

This is one of those things I never understood: if there are revision 
numbers printed on the boards, then why is there another hidden revision 
underneath that's not indicated directly anywhere.  We had this same 
issue with the Unleashed, where there were a whole bunch of different 
boards all of which were revision A00.

If you're sure that none of these other boards made it into the wild 
then I'm fine dropping the A00, but if there are boards that won't work 
with this DT in the wild then we should have something for those.  I 
don't know (and don't really care that much about) the naming scheme, 
just that it's unique and that users can tell which flavor they have.

I have one of these, but I haven't opened the box.  Is there some way to 
tell which version I have?

numbers printed on the boards, then why is there another hidden revision 
underneath that's not indicated directly anywhere.  We had this same 
issue with the Unleashed, where there were a whole bunch of different 
boards all of which were revision A00.

If you're sure that none of these other boards made it into the wild 
then I'm fine dropping the A00, but if there are boards that won't work 
with this DT in the wild then we should have something for those.  I 
don't know (and don't really care that much about) the naming scheme, 
just that it's unique and that users can tell which flavor they have.

I have one of these, but I haven't opened the box.  Is there some way to 
tell which version I have?
