[U-Boot] Davinci: add support for ea20 board
This patchset superseeds the patch with the same name. Common code is now shared for da8xx boards.
The patchset is based on the following patches:
Sughosh Ganu: Move and rename common headers from under board/davinci Ben Gardiner: da850evm: Add RMII support for EMAC
As more Davinci 8xx board can be added, move common code to be shared between boards.

I was unable to test this series on top of Sugosh's and my patches even after re-basing my patch on top of his by moving the da850_emac_mii_mode_sel declaration from board/davinci/da8xxevm/common.h to the location from which you have removed it above.
It looked like the removal of this file also needs to move the kick register declarations that Sugosh added here.
I'm guessing you are working from a tree that is very close but not quite equal to mainline plus the patches you referenced in the cover letter.
I don't know what is the best way to proceed... I like the current state of this patch series. I was unable to apply the three patch series (Sugosh's, Yours and mine) in any order without conflicts.

Let's see. I am working on TOT of u-boot mainline, and I have applied Sugosh's and your patch. Last u-boot commit in mainline is:
commit 8ad25bf8d9233eb7d0b614612108622a59069354 Author: Ben Warren biggerbadderben@gmail.com Date: Tue Aug 31 23:05:04 2010 -0700
Net: clarify board/cpu_eth_init calls
I have then applied in the order the two SPI flash I have already sent and you tested, Sugosh's patch and your patch. At the very top there is my patchset. This is my git log, I drop some part of the commit id to avoid wrapping:
6a1b17dd5cdaeb4c Davinci: add support for the ea20 board 5195253f20d5bedb Davinci 8xx: Move common functions to share code 8e6ed317d74b3b4d da850: Add RMII support for EMAC 9c1455c63dafc292 Move and rename common headers from under board/davinci. 4ccdfedb55b65f30 da850: Enable SPI Flash 0aacad5f81caac89 da8xx: Add cpu_is_da8xx macros 8ad25bf8d9233eb7 Net: clarify board/cpu_eth_init calls ^ |------- this is actual u-boot TOT
I think it is correct - patches are always sent on the actual u-boot TOT. However, in this case my patches need that other patches (yours and Sugosh's) are applied. I have tried to apply patches in the same order I have seen, but we can have a different order.
I don't know what is the best way to proceed... I like the current state of this patch series. I was unable to apply the three patch series (Sugosh's, Yours and mine) in any order without conflicts.
Let's see if something is missing ;-)
Best regards, Stefano Babic
Hi Stefano,
Sorry for the long delay. I thought rebasing my patch onto Sugosh's series would be a good start to getting all of our patches applied together. What I didn't realize was I that I still did not have the order of patches you listed below.

The problem was that I was applying my RMII patch on top of Sugosh's patches without your SPI flash patches underneath. Another RMII version patch is coming.
Still, there were some merge conflicts due to the fact that you were basing your ea20 patches off of only 1 of Sugosh's patches. here is the 'git log --format="%s -- %Cgreen%an <%aE> %Cred%ai" u-boot/master^..HEAD' output after all the merging.

You didn't have "Add board support for hawkboard" and "Remove board_init_f function from nand_boot.c" applied.
I hope you don't mind that I merged them and pushed the result to branch "testing-ea20-plus" of git://github.com/BenGardiner/u-boot-bg.git . I hope that saves us some time.
I will be sending a V4 of the RMII patch -- as can be seen from that series -- to the list. I hope you can use the merged patches in the branch I pushed to send your updated patches.

Right. Sugosh pointed me out to this patch and I have not seen that the patches for the hawkboard change something in common code, too.

Thank you for doing that - we have already a working tree !

I will test today on ea20, but it seems all what I have to do is only to send them to the ML - thank you again for your work !

I guess i will have to send an updated version from Ben's tree, as he has fixed some merge issues in "Add board support for hawkboard" patch. The patches would have to be committed in the same order as mentioned above.

Yes, I did the same for mine as Ben has rebased my patches and they are different as the ones I send to ML.

I have been tracking this e-mail chain for some time now and I have lost track of which patches to apply in which order.

track of which patches to apply in which order.
Can someone please give me the correct order and the correct version
of
the patches?
The correct order and correct versions of the patches can be found in branch "testing-ea20-plus" of git://github.com/BenGardiner/u-boot-bg.git. The commit messages there do not include Sugosh's Tested-by: tag on the hawkboard patches, nor has he re-sent them to the ML yet.
I tried to access that page but failed.

I'm very sorry for the trouble you've had accessing that repo -- I will happily switch to any other public git hosting service of your choosing for future merged series.

Not an issue at all.
In this case because of some major changes and multiple patch versions I lost track. Usually I pick it from the mailing list.
After Wolfgang accept my previous pull request, I'll get on with the program of merging these patches.
Thanks, Sandeep

I think you would need to rebase your patch 'da850: Add RMII support for EMAC', on top of my patches. I had made changes in the include/asm/arch-davinci/hardware.h and moved the board/davinci/da8xxevm/common.h, both of which you are making changes to. Stefano's patch series should then apply on top of your rebased patch. Missed out your patch, else would have flagged you in advance. Sorry about that.

Hi Ben,
there is at the moment no plan to add support to ea20 for USB or SD. However, Things could be changed when a new revision of hardware will become available (at the beginning of next years).
Patches to add SD support was already sent to the ML, I see the ACK by the MMC maintainer:
http://www.mail-archive.com/u-boot@lists.denx.de/msg32375.html
It seems to me the only reason the patch did not go to the mainline was to understand who should merge it and then push to Wolfgang.
Probably what we need is to check again the status of this patch. I cannot find it on patchwork, it looks like it was missed ;-(.

Nice finds. Both of those patches look applicable -- thank you, Stefano. I can't say that I will be starting an effort to apply/port these to da850evm immeadiately. But now I have a great place to start when I do.

Sadly that patch never made it to the mainline
It seems to me the only reason the patch did not go to the mainline was to understand who should merge it and then push to Wolfgang.
Usually I take small changes to the other subsystems with an ACK from the maintainer and I merge it myself. The series in question was part of a set of I believe 9 patches which made quite a few changes to the MMC subsystem.
I asked the author to resubmit patches quite a few times but have not received a response. If anybody can do the rebasing and testing that would be welcome.

Sorry for the late response. I will start working on getting the USB stuff in after the base port has gone into mainline. This might take some time though, as i am not much familiar with the USB related code.
