Dear Pali Rohar,

I suggest you to read through this whole mail properly, do not get angry by the 
first few lines.

Firstly, we are very grateful for properly reported bugs!

Yet you probably misunderstood how whole this free software/open source thing 

If you found a bug noone else noticed, you are not ever supposed to expect 
people on the mailing list to fall on their backs, drop everything they are 
doing and start fixing your problem. This is because they didn't observe any 
trouble and so this has no priority for them.

And this is especially true for out-of-tree ports. N900 is good example of such 

Now if you actually report a bug to the mailing list and this bug goes unnoticed 
for an extended period of time, you're supposed to send subsequent email in 
order to alarm the people on the mailing list the bug report is still relevant.

In case of U-Boot and Linux kernel, there is a list of maintainers in the 
MAINTAINERS file in the source tree, you are supposed to put these people in the 
Cc of such reports, this will greatly improve your chance of getting response 
and help. In case of U-Boot, there is also a list of custodians available here:


But considering you are yourself a software engineer, the best approach to the 
problem you're observing is to actually debug the issue you're seeing and submit 
a patch for it. Next, fix your patches for N900 and submit them. It'd be a good 
idea to put a note in the patchset cover message that this depends on your 
previous fix.

Now, to the problems you're observing:

1) Video; check if you have the following defined in your board config:


I understand that you probably want to second and the last define from the list 
above, which solves your "invert" problem and swcursor problem.

2) MMC; I believe Tom can comment on this one.

On a final note, I believe you should adjust your behaviour towards the mailing 
list. The U-Boot project, as well as many other FOSS projects, is a collective 
effort to achieve the best possible result for everyone. But for such model to 
work, everyone must first give and take only afterwards and never too much.

Best regards
Marek Vasut
