[U-Boot-Users] [PATCH 0/3]Patchset for Ati bios emulator and Ati frambuffer driver
Hi, Stefan
This patchset add Ati bios emulator and Ati video card framebuffer driver to u-boot. The bios emulator and the framebuffer driver work for Ati PCI and PCIE video card. We tested the patchset on 9200 PCI card, X300, X700 and X800 PCIE card in u-boot on MPC8641HPCN board. After the video card bios finish runnig in the bios emulator, We can use the Ati framebuffer driver in u-boot, we can also use the radeon base driver in kernel directly for those Ati video card.
Thanks, Jason

Ati bios emulator - Why do we need another emulator? Is the one we have in board/MAI/bios_emulator/ not sufficient for your purposes?

Hi, Wolfgang,
Thanks for your feedback, Please see my inline comments.

Each of the two patch is a logical part and I think they should not be split into separate part, I'll try to provide a URL for the two patches.
Ati bios emulator - Why do we need another emulator? Is the one we have in board/MAI/bios_emulator/ not sufficient for your purposes?
Yes, I found there's a bios_emulator in board/MAI/bios_emulator, but it's board specific and I can not use it directly, actually both of the emulator come from Scitech, I tried to make it clean and clear during my porting. On the other side, I tried to compile it for the MAI board but compile failed. If other board want to use the bios emulator, I suggest moving it out from the board and make it clean.

Well, ok, but actually this has nothing to do with the line length of your postings on this mailing list, right?

Can you please do that, then? It's the logic consequence. I do not want to add another 800 kB of code for a feature that is already present. If cleanup and.or generalization is needed, then this is what has to be done. If you find that your solution is better than the existing one, you have to prove that and replace the old one.

Wolfgang Denk

Ok, I'll try to fix this next time. And I'm trying to find a place to put the patch.

board/MAI/bios_emulator, but
it's board specific and I can not use it directly, actually both of the emulator come from Scitech, I tried to make it clean and clear during my porting. On the other side, I tried to compile it for the MAI board but compile failed. If other board want to use the bios emulator, I suggest

Actually, The BIOS emulator I posted and the BIOS emulator in board/MAI are both come from SciTech. But as it's under the MAI board, my understand is if I want to use it for different platforms, I need to move it out and try to cleanup it and make it pass compile and make it work (The BIOS emulator under MAI board is about 6M and I don't know if some files such as the bat files and win32 directory is useful for u-boot).
So I think it can be interpretated as I've moved out and cleanup the BIOS emulator from MAI board. But I haven't MAI board in hand and can not test if the board can work normally after remove the bios_emulator. So I did not send a patch to remove the code in the board/MAI. I can only test this 'moved out' BIOS emulator on the board in hand such as 85xx,86xx and 7448 board. If I can contact with the maintainer of the MAI board. Maybe she or he can help to test this.
Thanks Jason

That was my impression that it's based on the same code. Which is why I think that needs to be cleaned up.

I think you are right - there is some crap in this directory.

Understood. Well, but at least we can try and (1) remove the (board specific) BIOS emulator from the MAI board directory and (2) switch to use your commin implementation yet.
If you can proivide a patch that the MAI still compiles and links, that wouldbe a good base that other users could test it - I hope there are still MAI users around? [Otherwise we can simply remove the whole board support? ;-) ]

That's what I hope, too. Alternatively, at least some MAI users would be able to run some tests.

I'll try to found out a way to minimize the impaction to MAI board when the bios_emulator was moved out.
Is there someone using this board and can afford some information about the board and help to test? Seems like it's a rather old board.
