Ok, thanks all for dumps!

Results:

* All dumps with revision 2101 are same.
* All dumps with revision 2204 are same.

I do not need more 2101 and 2204 dumps. But I have only one dump for revision 2104. Please if somebody has N900 with other hw revision (not 2101 and 2204), please attach dump.

OMAP tabe is same for all dumps (2101, 2204 and 2104) (differences in hw-build and bootreason I'm ignoring for obvious reason). So I think this OMAP table can be hardcoded into U-Boot.

But there is one big difference between 2101 and others (2104, 2204).

2101 has two MEM tags:
ATAG MEM size=08000000 start=80000000
ATAG MEM size=08000000 start=88000000

but 2104 and 2204 only one:
ATAG MEM size=10000000 start=80000000

total size of RAM is same, but I have no idea why 2101 has it devided...

And I checked RX-51 fiasco firmware and X-Loader and NOLO images are same for all 21** and 22** revisions. No idea how can NOLO detect correct revision and pass different MEM atags...

@drucula, thanks for dump!

Now we have 2 different dumps for 2104. Both are from Britain. But one has only one MEM atag and second has 2 MEM tags, which is bad. I thought that NOLO create that MEM tags from HW revision, but now I this is not true.

Has somebody idea how can NOLO detect if it could pass 2 or 1 MEM atags? Note that both devices are same 2104 and has same NOLO version. I have no idea now...

Have you tried pinging Xlab? From the post he wrote: http://talk.maemo.org/showpost.php?p...49&postcount=6 i guess he knows nolo quite well

you may also try pinging other guys active in threads http://talk.maemo.org/showthread.php?t=75504 and http://talk.maemo.org/showthread.php?t=83880 as they seem to know nolo a bit.
